Sorin: Since I watched this video, I've been making my own liquid flux using the rosin you say to use. And it's now 2022 and I still only use it. It works great Thank you my friend.
I must thank you! I have been soldering for more than 40 years and have NEVER seen anyone actually perform a side by side comparison of flux (paste/liquid) Vs Rosin (solid/mixed). KUDOS!
Damn i love this guy. 1. Im trying to figure out what word he substitutes "yeah" for. 2. He is trying his best to educate the little people. And that is golden. I just wish I lived by him. So i could go there everyday i could. To learn from him.
I follow F1 racing and Indycar racing. Four time world Champion Sebastian Vetall, who is German intersperses yeah all the time which is a German thing. It seems to me all manner of racers have picked this up from Vettal. British folks often end sentences with “Isn’t it” of the like. “Vettal had a great career didn’t he?”
Hey man, i wanted to thank you alot! I bought myself a laptop for 20€ Asus with i5 4th gen. Gtx 840m (won't turn on) also I bought a multimeter, heatgun and some soldering stuff. I watched alot of ur videos, because I had no idea what it could be.. with the multimeter I found that the first mosfet had 19V input, but not output.. my first soldering looks like shit...BUT I got it back to work again!!!! So I wanted to share and say thank you! 😊 Keep it up!
Michele De Stefano Mosfets usually fail short circuit. When that happens they can take down other components with them but that depends on the circuit they are in.
I tried your home flux recipe and man, it worked amazing. I challenged it on the same board against (famous) Amtech 559 and solder made with the mix you recommended worked flawlessly. Joint is more elegant than the one made with Amtech. Amtech leaves a bit less brownish resin behind, but it's fine by me as Im always cleaning my boards with isopropyl alcohol afterwards anyway. Big thank you!
@@christosmakariou4574 It is crushed rosin mixed with isopropyl alcohol. The mixing ratio is not that important. You add more rosin or more alcohol until you get the desired viscosity that works best to you. I am using this liquid flux when I want to protect traces on PCB and i don't have solder mask. You just apply this liquid flux and let it dry.
This was such a huge help for me. As a person who repairs things for friends and my own equipment when I'm home this is a great tip. The liquid flux also goes bad relatively quick but I imagine resin in pure form will last years and years until I need it. THANK YOU!!!
Tot respectul pentru Dumneavoastra . Ma bucur sa vad ca acestea detalii fac o mare diferenta in electronica pentru mine cat si pentru toti cei care va urmaresc cu drag . Va doresc multa sanatate .
You're like the friend I never knew I had. I love your videos and your accent. These videos are highly educational and useful to anyone that's getting into the field of electronics. A credit to all IT junkies and engineers. Thank you, man! Thank you.
I had an Electric fire that developed a problem. When I got to the circuit board, it had fried an IC. So! It had burnt the board. I used soft silicone wire. To rewire the new chip onto the traces. And! I used this flux as you showed.Unfortunately in present times.IPA is very difficult to obtain.So I used “methylated spirit” it worked. Dissolved the rosin. And I used that. It was a brilliant flux. And the fire works a treat. Thank you for this vid. I know what I will use from now on. 👍👍 Yes pine resin.Smells great.
Sorin does not just teach you electronics repair, he also teaches the tradition and culture of electronics, generations of craftsmanship and resurrecting machines. This is why I love Sorin.
I just wanted to say how greatful I am to have found your videos! I wanted to encourage you that what you do is helpful to alot of people! It is unfortunate that so many people have negative things to spew out of their ignorance! Its disgusting the condition of humanity these days! What you do matters and I hope you dont let ignorant people discourage you!!!!!
Hi. Thankyou so much for sharing, I'd had to wait for half an hour for you to find your different fluxes but it worth it!! Just for you and other people to know: if you want to buy rosin or colophony for REALLY cheap search the one classic dancers are using on their shoes. It's exactly the same colophony you're using for soldering but it sells in bags of 500gr for something like ten dollars!!!
I know exactly what you mean. My first experience of soldering was around 1970 when I was still a boy. I just love this smell it brings me back to that time. Recently my wife gave me some out of date mastix (mastic) which I use as flux. It smells exactly as the flux in the old days. I have never smoked in my life but I could inhale this smoke all day and enjoy it.
Hello Sir, I made a flux from rosin and nail paint remover right now. Its cost me around 25 rupees per 100 grams and thinner for just 30 rupees total cost was 55 rupees. And this one is best flux. Thanks for explanation.
Greetings from the US Gulf Coast. The reason folks use a fume extractor is not the rosin - it's the solder. To use one or not is a personal choice, but folks in the electronics craft tend to have higher blood lead assays than most, and that's not a good thing. Rosin flux has been around for years, and is still one of the best types for electronics work. The clear stuff looks like rework flux. Seems like it would be handy enough for the kind of work you do. Melting rosin goes more easily if it is finely powdered. An improvised mortar and pestle works well enough for this. Rosin attracts water, so keep rosin powder in a dark container when not in use. For those of us not using e-cigarettes, save the empty bottles from Shave Secret shaving oil or from any of several eye drops. Good stuff, man! I mean to try making my own solder flux as soon as I can collect some pine rosin.
Just to clarify this for people who are new to soldering: even good quality solder that contains rosin flux already (as all electronics soldier should) will not work very well if you put a blob of it on the tip of the iron and carry it over to the work, because the flux is already evaporating and burning off from the second that the solder is melted onto the tip. Enormous sattering you clean the tip of the iron wet it with a little bit of solder, apply the tip of the iron to the area being soldered and touch your satyr wire to the connection close to, but not actually touching, the tip.
Best electronics channel on youtube. I just love it. Thank you for education. It's inspirational tutorials like these that save the planet from electronic waste. Love the making your own flux. You can clearly see it can withstand a higher temperature coefficient - which protects the chip from over heating when both salvaging parts or replacing parts.
Sir Rosin is very fantastic flux. And you know it's very cheap price in pakistan . I am also useing this. But it's was very interesting lesson to make liquid flux. Thanks a lot my teacher.
Thank you Master Sorin, Once i started viewing your video, I'd never escape evening single second just to get learn from your demo/actual technique. You are amazing and most of the other videos i'd watched, yours is totally clear in details.
I know this is an old video but, straight from Wikipedia and just for fun: " , also called or (Latin: ), is a solid form of resin obtained from pines and some other plants, mostly conifers." And this is why it smells so good ha h ah ha a ha haha h a! Спасибо, мой друг, Merci mon ami !
I just got my 100g of Rosin Flux today after ordering it last year September, I didn't think I'd get it as our post service in South Africa is the worst in the world!!! But finally, it arrived... Looking forward to using it and thank you for the recommendation!
WOW you are right this is the best flux I have ever used! All my soldering connections are much stronger. This flux really lets or make the solder flow so easy and nice. The price is cheap too. Thanks
I'm not sure if it is known all over the world, but in Germany there is something they call "Löthonig" = "soldering honey", it is basically exactly this mix of colophonium and isopropy-alcohol, hobbyists use often benzine and less clean alcohol and it works too, but the sense is to make a thick paste so it looks and feels like honey, that stuff is great and ready made pretty expensive. I want make both, honey and liquid, but still wating for my colophonium from China, step by step I'm gonna test all the diy recipes I can find, solder paste is also on the plan :)
I know this is an old video but I just found it. I used your formula for flux and it's working great. I'm guessing my cost for a 20ml bottle is about 15 cents, maybe less. My last 15ml bottle was $10. Not bad!!
Thanks for the video. I always used pine rosin, since the late 90s, and to this day I cannot find a replacement that comes closer to properties of the pine rosin when it comes to soldering electronics. In fact, most of the time I used to search among pine trees for chunks of rosin ready to be collected :) sometimes cleaning it beforehand and "purifying" was needed. overall, a great companion to every electronics technicians.
Fitting in with what was said in this video, rosin is a mixture of abietic, isopamaric, isopamaric and other weak organic acids with a softening point of approx 76C (169F), melting point of 140-176C (284-349F), and b.p. of 425 - 440C (797-824F).
In a closed glass bottle and in the ultra sonic bath it is faster. OIn an open bottle in warm uS bath if the mix is too fluid. I would use the hot air to warm the mix It works as expected, while some paper towel a brush and isopropyl alcohol are mandatory to clean the residue. I noticed on videos that some pros use special "towels" that leave no fiber, to absorb the residue of flux. It is cleaner than brushing with alcohol (and the brush bristles are kept more clean, not polluted with rosin) However, I noticed that your rosin is more yellow than brownish, certainly a sign of quality
maybe i was lucky guy and got no fake but i just want to tell that im using the Amtech flux for several years now and made very good experiences with BGA on the IRheater. It stays liquid and clear through the whole process and needs a lot of heat before evaporating.
Thank you for sharing, I can’t believe how much I have missed hearing different accents, yours is rich and reminds me of friends from the past and appreciate you sharing knowledge and experiences with comparisons. Now I wonder how they all are doing, was great to be surrounded with different languages and understanding beliefs etc. Thank you for sharing and hope you have a great day!
@@ten10ca I enjoy because it shows there is more to this world to know and acknowledge, the beliefs to superstitions that are different to understand, cultural upbringings that is great to share, new lands to be exposed to. I am an optimistic in some ways that there are people like you and me that just want to share knowledge that today’s society and media doesn’t want the general to know since you don’t have to throw money into it as much as the next product they are pushing. I have a pancake mix my family loves and haven’t had to buy the store brands in years and only recently few others understand that it is the little things shared that we appreciate instead of having it constantly similar to what is expected. Rambling and random but it is awesome in it’s own uniqueness just as I appreciate your time sharing how effective simple ingredients compared to what is bought is better.
This is absolutely crazy! Those expensive flux is, expensive! And then on top of that, they are not easily available in my area or even closeby cities. I have suffered tremendously over the years due to lack of good flux as a hobby soldering person. But I had these $1 cheap ones available in like a 2 minute drive from where I live and I have ignored these all these years thinking they were "cheap" and "not worth it"! Little did I know, these were the best one the Earth had to offer 😅😅 And these also sell for like $0.10 per 20g. 😅😅 I am surely buying some of these Inshallah. A big thank you, Sorin. ❤❤ This made my day today, Alhamdulillah!
i start fall in love in electronics when i saw your videos on youtube...sir 😁😁😁 your are great electronics teacher .... i am one of your Big One.....hope you will never stop showing your technic to us....specially for me... i am to newbei for this... and i want learn more......thank you so much sir....
Salut Sorin,foarte faine clipurile tale de reparatii,sper sa o tii asa mult,crede-mă că cel puțin eu personal învăț mai mereu din ele câte ceva nou.Cât despre acest video,mai folosesc înca la lipituri sacâzul,cum îi spunea pe vremea mea în tinerețe,este foarte bun,ai dreptate.Oricum,mulțumesc pentru video ,ține-o tot asa.
The substance he is using here to make electronic soldering flux is called: "Colophonium" or "Colophony". This is a fancy name for the naturally occurring yellow resin (rosin) from the Yellow Pine Tree. Prepared rosin flux comes in 50gram tins for around $6 to $9. You can buy 1.5 lbs. of "Colophony" rosin for $16 and make your own dissolving it in isopropyl alcohol - That's equal to 13 tins, enough to last quite awhile.
Tree resin/rosin, frankincense and myrrh; some uncircumcised philistines on this board hate incense. Kolophonium (pine rosin) does have a pleasant smell. As to Boris here liking the smell of mineral spirits is another matter.
In Romania, in the old days until now, we use this kind of flax, Kalafonia, called "sacâz" and Sorin, of course, knows this because probably started electronics here. We also had a recipe of various substances, mixed with alcohol that dissolves them to make a good liquid flax, kolofonia was principal substance in this mix
Sorine, capacul cutiei de colofoniu are o buza ridicata in sus, dar pe o portiune nu are buza ridicata, acolo strange cutia intre degete ca si cand ai vrea sa o inchizi dar se va deschide in partea opusa... succes
old school ! my first EFT been soldered like that! I'm still using this! I was in remote location, but still having a little 5V soldered pen..but no flux! I used resin from pine tree..it works great!
Thankyou sir, ive learnt something which i never would have . May God almighty grant u long and healthy life for taking time out to share you knowledge.
Thanks for your info on this. Have had so much trouble buying a decent RMA flux or a paste & none have worked, even the most expensive. I can’t even buy liquid types now because airlines won’t carry it to my country! Just bout 10 tins of this... to make my own.
Thank you Sorin, I would love to see a video made by you explaining how to use an oscilloscope to trouble shoot chip and settings Thank you for the great work
Yes dear Sorin, You are great teacher and I thank you . I have been in electronics (in and out) for nearly all my life but you have thought me more in just a few videos than what I have missed in my past . Thank you professor 👍🙏
Even if there's not the same chemicals in pure pine rosin you should still always use a fume hood. There's studies that show it still causes allergies and other respiratory issues. It's also only temporarily vaporized, when inhaled it'll cool down and stick to the inside of your lungs, like some "natural" subtances used in bootleg vapes, ppl just assume things aren't dangerous when its "natural", but vaporizing and inhaling some substances is still dangerous to us
I remember as a little boy, I fell inlove with the smell of the solder flux. I used soldering wire with flux inside it . Watching you with the smoke brings back memories LOL
cool channel. I subbed. I am new to soldering, I want to work on some gaming consoles, xbox, xbox360, playstation, and I bought "Flux" from my electronics store, and when I opened it it was "just" Kolophonium hard, and I had no clue how to use it. Thanks to your video, now I know. I'll dissolve it in Isopropyl alcohol.
Aí é foda hein amigo, tu solda de um jeito (do jeito errado) no começo e depois que coloca o fluxo vc faz do jeito certo e não fica balançando a ponta do ferro feito alguém com mal de parkinson, aí não dá pra por fé que é algo realmente tão melhor que o fluxo que já vem com o arame de solda 😅
Fun fact: If you dissolve the rosin in warm methanol and then soak pine or spruce sticks in it in a sealed jar for a week you can make yourself some fatwood firestarter. Isn't as good as the natural thing but it does a pretty darn good job.
I just bought this rosin flux by mistake (thought it was a paste) and believed I was stuck but looking at your vid I think it'll do the job nicely ..Thanks .. Yeah :P
Wow thank you! The difference in price is vast and it can stay like that now. I'm grabbing some solid Rosin and dissolving it in Isopropanol to make a batch up because _Common Sense_ I Vape too, so the empty Juice Bottles will be useful
In the beggining, the solder does not stick to the pad because you have to heat it first. Flux makes soldering better but it is possible to solder without it
Another video channel says that adding glycerin to your home made rosin liquid flux helps to stop it going a burnt colour when applying heat - you only need a few drops - add 1% by weight to your liquid flux
I agree rosin is the best. Sometimes when rosin does not work I use Lötfett LF20. It is super cheap and you will solder everything with it. Downsite is that is is little bit acidic, so you should clean it.
Fantastic video - I've ordered some Rosin Flux as you recommend (I already have some isopropyl alcohol) so cant wait to make my own liquid flux! Thanks :)
When you wrap the rosin in a paper towle and smash it slightly with a hammer a few times it becomes like powder. This powder solute in alcohol within minutes.
WOW, I never knew you could make liquid solder using isopropyl alcohol. No need to purchase any more Amtech solder now. I recommend to SUBSCRIBE because ERS is sharing over 20+ years of secrets and experience. I just wish these videos were on TH-cam sooner because I could have done so much more. Hopefully I can share some things that will help ERS too. Thanks for sharing!
The smell brings me back to a 1979 audio shop, for some reason all the speakers and audio equipment smelled like rosin, it is how you knew you were in a audio equipment store of the era.
Again great tip! I learnt to solder when I was aged in single figures and have been for 30+ years now but was never really taught the importance of flux, wrongly assuming that flux-cored solder was enough - it's only after watching re-work videos that I recently bought a 50ml bottle of liquid rosin flux which was about 5 quid - it will probably last me a lifetime as a hobbyist, just just like my reel of full-fat leaded solder which I've had since the 80s ;) I might make up some of your home-brew flux to compare :)
Thanks a lot for this! Now i will make my own soldering flux for like no money, 1000g of calaphony in Poland cost 4 pounds, so i will make lifetime stock of it.
I have used in the past a mix with acetone and rosin. The funny part is that some countries has banned already the rosin along with other flux products. There is the reason "Soldering with lead (or other metals used in soldering) may produce fumes that are hazardous. In addition, using flux containing rosin (also called colophony) produces solder fumes that, if inhaled, can result in occupational asthma or make existing asthmatic conditions worsen. The fumes can also cause eye and upper respiratory tract irritation. "
Its the same rosin as used in the musical world. But what he is buying off of Ebay is actually in Flux form. If your buying the big brick of rosin. You can smash it until it turns into a powder. Then mix it with isopropyl and if you add about 2-3% glycerin by weight. You will have some really good stuff. You'll have to play with your alcohol % but it can be anywhere from 50-80% depends on how you like it. You know its rosin flux because its in those thin crystal pieces already. But its probably over 80% pure rosin that is why its not a liquid or paste. But also why its not a dry brick or powder. The rosin flux he shows can't be purchased in the USA. You have to use ebay uk to get it delivered. But you can buy resin all over just find a local music store.
@@yosyp5905 Yes, it is the same stuff. It dissolves happily (but slowly) in ethyl alcohol and isopropyl alcohol. Rosin is a plant gum product and contains organic acid. Some small amount of inorganic acid is added to make mildly activated. With exposure to air, it turns darker (oxidation) over a period of time and loses its activity. The light colored stuff is better.
Rosin with rubbing alcohol works fine, except it drys out pretty fast. As far as the fumes go, it gets in my sinuses and gives me a headache, so I use a fume extractor. I like the smell though :P
This guy is the best. Nothin fancy just works and works well I might add. I use the same stuff (kalafonia) much better than other more expensive fluxes.
You are right Rosin is the better one solution for soldering and unsoldering everything thanks to his high boiling capacity and properties, but just an advice, I know that the smell is great but is highly carcinogenic!! This is why many people have the fumes sucker or a well ventilated laboratory..great explanation and great video though! P.S. your microscope is awesome!!
the quality nis probably better than buying colophon powder (but colophon powder comes in different qualities, whitened, or not ; this is used to make varnish for musical instruments soundboards

Was the mosfet with no output the problem? Or you found something else shorted?
Michele De Stefano
Mosfets usually fail short circuit. When that happens they can take down other components with them but that depends on the circuit they are in.
Anyone can answer am I fine with just using white rosin ? Or do I need to make my own flix using isopropyl alcohol and rosin ?
learning how to fix your own stuff is one of the best investments one can make
If I could go back 50 years and apprenticed in in electronics repair shop, I would have wanted you to be my teacher. Thank you for your videos.

You can also use rosin flux to create a white cover on components which can be helpful when locating components that are getting hot.
So if you use this were components gets hot, you may get shorts? That's not a very good idea.
Just to clarify this for people who are new to soldering: even good quality solder that contains rosin flux already (as all electronics soldier should) will not work very well if you put a blob of it on the tip of the iron and carry it over to the work, because the flux is already evaporating and burning off from the second that the solder is melted onto the tip.

Fitting in with what was said in this video, rosin is a mixture of abietic, isopamaric, isopamaric and other weak organic acids with a softening point of approx 76C (169F), melting point of 140-176C (284-349F), and b.p. of 425 - 440C (797-824F).
In a closed glass bottle and in the ultra sonic bath it is faster. OIn an open bottle in warm uS bath if the mix is too fluid. I would use the hot air to warm the mix It works as expected, while some paper towel a brush and isopropyl alcohol are mandatory to clean the residue. I noticed on videos that some pros use special "towels" that leave no fiber, to absorb the residue of flux. It is cleaner than brushing with alcohol (and the brush bristles are kept more clean, not polluted with rosin)
However, I noticed that your rosin is more yellow than brownish, certainly a sign of quality
maybe i was lucky guy and got no fake but i just want to tell that im using the Amtech flux for several years now and made very good experiences with BGA on the IRheater. It stays liquid and clear through the whole process and needs a lot of heat before evaporating.
I also learned soldering and electronics with pine rosin as flux. Love its smell
Thank you for sharing, I can’t believe how much I have missed hearing different accents, yours is rich and reminds me of friends from the past and appreciate you sharing knowledge and experiences with comparisons.
Now I wonder how they all are doing, was great to be surrounded with different languages and understanding beliefs etc. Thank you for sharing and hope you have a great day!

@@ten10ca I enjoy because it shows there is more to this world to know and acknowledge, the beliefs to superstitions that are different to understand, cultural upbringings that is great to share, new lands to be exposed to. I am an optimistic in some ways that there are people like you and me that just want to share knowledge that today’s society and media doesn’t want the general to know since you don’t have to throw money into it as much as the next product they are pushing. I have a pancake mix my family loves and haven’t had to buy the store brands in years and only recently few others understand that it is the little things shared that we appreciate instead of having it constantly similar to what is expected. Rambling and random but it is awesome in it’s own uniqueness just as I appreciate your time sharing how effective simple ingredients compared to what is bought is better.
This is the best video on flux ever made
This is absolutely crazy! Those expensive flux is, expensive! And then on top of that, they are not easily available in my area or even closeby cities. I have suffered tremendously over the years due to lack of good flux as a hobby soldering person. But I had these $1 cheap ones available in like a 2 minute drive from where I live and I have ignored these all these years thinking they were "cheap" and "not worth it"! Little did I know, these were the best one the Earth had to offer 😅😅 And these also sell for like $0.10 per 20g. 😅😅 I am surely buying some of these Inshallah.
A big thank you, Sorin. ❤❤ This made my day today, Alhamdulillah!
i start fall in love in electronics when i saw your videos on youtube...sir 😁😁😁 your are great electronics teacher .... i am one of your Big One.....hope you will never stop showing your technic to us....specially for me... i am to newbei for this... and i want learn more......thank you so much sir....
Salut Sorin,foarte faine clipurile tale de reparatii,sper sa o tii asa mult,crede-mă că cel puțin eu personal învăț mai mereu din ele câte ceva nou.Cât despre acest video,mai folosesc înca la lipituri sacâzul,cum îi spunea pe vremea mea în tinerețe,este foarte bun,ai dreptate.Oricum,mulțumesc pentru video ,ține-o tot asa.
The substance he is using here to make electronic soldering flux is called: "Colophonium" or "Colophony". This is a fancy name for the naturally occurring yellow resin (rosin) from the Yellow Pine Tree. Prepared rosin flux comes in 50gram tins for around $6 to $9. You can buy 1.5 lbs. of "Colophony" rosin for $16 and make your own dissolving it in isopropyl alcohol - That's equal to 13 tins, enough to last quite awhile.
Which continent produces this yellow pine tree?
Who needs an extractor, start your day with a deep breath of Kolophonium, aaaaaahhhh there's nothing better
🤣👏🏻
Naughty Finger yes there is, Phenibut,
There is nothing better than an afternoon nap with a rug soaked with acetone on your face
Puts hair on ur chest Matie !!!
hes on his 15th lung transplant
Tree resin/rosin, frankincense and myrrh; some uncircumcised philistines on this board hate incense. Kolophonium (pine rosin) does have a pleasant smell. As to Boris here liking the smell of mineral spirits is another matter.
In Romania, in the old days until now, we use this kind of flax, Kalafonia, called "sacâz" and Sorin, of course, knows this because probably started electronics here. We also had a recipe of various substances, mixed with alcohol that dissolves them to make a good liquid flax, kolofonia was principal substance in this mix
Sorine, capacul cutiei de colofoniu are o buza ridicata in sus, dar pe o portiune nu are buza ridicata, acolo strange cutia intre degete ca si cand ai vrea sa o inchizi dar se va deschide in partea opusa... succes
by far the best electronics info i have seen. very well done and explained clearly.
I just used some reclaim from my dab rig, shit works great, and like you said that rosin smoke just hits different🤙😉
dababadoo
I also love the smell of flux -- One of the best things about soldering!
Chaos rules ...more like a comedy show 😂😂😂
old school ! my first EFT been soldered like that! I'm still using this! I was in remote location, but still having a little 5V soldered pen..but no flux! I used resin from pine tree..it works great!
I love you
You are like a dad to me. I like how you explain things
Live long ❤️
You are my inspiration Sorin. With love, Manasseh Mukuwa in Zambia-Africa
Kalafonia is very popular in Poland... cost about 1 Euro :-) I use that flux to protect corosion prototype PCB - painting them. IS PERFECT
I love the smell of JP4 I flashback to my times dealing with jets.
Rosin, anagram for Sorin. Maggiiic 😀
rinos too... horny or ornis if you like :))
Dušan Velemir very very clever sir!!! Love it! 🙂
Thankyou sir, ive learnt something which i never would have . May God almighty grant u long and healthy life for taking time out to share you knowledge.
Thanks for your info on this. Have had so much trouble buying a decent RMA flux or a paste & none have worked, even the most expensive. I can’t even buy liquid types now because airlines won’t carry it to my country! Just bout 10 tins of this... to make my own.
Nu m-am gandit niciodata la idea sa dizolv Fluxu-ul Rosin cu alchool isopropilic o idee geniala !!!!!
"I drop tears of flux" 23:21 Sorin you're such a god damn genius!
comment of the year
On another channel, they said to add a drop of Glycerin to the alcohol/rosin mix to prevent it from burning. I'm going to give it a try.
Thank you Sorin, I would love to see a video made by you explaining how to use an oscilloscope to trouble shoot chip and settings
Thank you for the great work
Yes dear Sorin,
You are great teacher and I thank you .
I have been in electronics (in and out) for nearly all my life but you have thought me more in just a few videos than what I have missed in my past .
Thank you professor 👍🙏
From Leicestershire UK 🇬🇧
Sacaz 😀, best solution.
I've just been using flux core solder for years, works fine.
Thank you for sharing your helpful experience.🙏🙏🙏
Even if there's not the same chemicals in pure pine rosin you should still always use a fume hood. There's studies that show it still causes allergies and other respiratory issues.
It's also only temporarily vaporized, when inhaled it'll cool down and stick to the inside of your lungs, like some "natural" subtances used in bootleg vapes, ppl just assume things aren't dangerous when its "natural", but vaporizing and inhaling some substances is still dangerous to us
I remember as a little boy, I fell inlove with the smell of the solder flux. I used soldering wire with flux inside it . Watching you with the smoke brings back memories LOL
The rosin smoke is main reason for soldering related asthma. If you work in factory and solder few hundred connections a day try to avoid it.
cool channel. I subbed. I am new to soldering, I want to work on some gaming consoles, xbox, xbox360, playstation, and I bought "Flux" from my electronics store, and when I opened it it was "just" Kolophonium hard, and I had no clue how to use it. Thanks to your video, now I know. I'll dissolve it in Isopropyl alcohol.
Aí é foda hein amigo, tu solda de um jeito (do jeito errado) no começo e depois que coloca o fluxo vc faz do jeito certo e não fica balançando a ponta do ferro feito alguém com mal de parkinson, aí não dá pra por fé que é algo realmente tão melhor que o fluxo que já vem com o arame de solda 😅
Hi Sorin, I did it & it works delightfully! Thanks for sharing!
this method is so old
This is fantastic, the smoke of this. I love to feel the smoke of .. of .. of the flux, of the ROSIN. (6:38) XD
Thank you for explaining your experience with flux. Perfect :D
Fun fact: If you dissolve the rosin in warm methanol and then soak pine or spruce sticks in it in a sealed jar for a week you can make yourself some fatwood firestarter. Isn't as good as the natural thing but it does a pretty darn good job.
I just bought this rosin flux by mistake (thought it was a paste) and believed I was stuck but looking at your vid I think it'll do the job nicely ..Thanks .. Yeah :P
Wow thank you! The difference in price is vast and it can stay like that now.
I'm grabbing some solid Rosin and dissolving it in Isopropanol to make a batch up because _Common Sense_
I Vape too, so the empty Juice Bottles will be useful
I love how dangerous everything is in this video. You gained a sub dude.
Just take a shot every time this guy says flux and you will become the flux.
In the beggining, the solder does not stick to the pad because you have to heat it first. Flux makes soldering better but it is possible to solder without it
top info , no wonder my solider was going like that and the solider had built in flux, just bought the solid rosin 40g 2 quid that brand as well
I use the same flux rosin. You get this in paste also which is nice stuff. A bit dark almost orange but really nice.
Thanks those you're nonstop to teaching us.. As a techinician l had got more knowledge from you..
Another video channel says that adding glycerin to your home made rosin liquid flux helps to stop it going a burnt colour when applying heat - you only need a few drops - add 1% by weight to your liquid flux
I didn't really know what rosin was before this.. but now I want to smoke it
Thank you very much, now I use your flux, it is cheap, and really efficient. And has a good smell, also.
I agree rosin is the best. Sometimes when rosin does not work I use Lötfett LF20. It is super cheap and you will solder everything with it. Downsite is that is is little bit acidic, so you should clean it.
Some people have fume extractors... some people ARE fume extractors.
Fantastic video - I've ordered some Rosin Flux as you recommend (I already have some isopropyl alcohol) so cant wait to make my own liquid flux! Thanks :)
When you wrap the rosin in a paper towle and smash it slightly with a hammer a few times it becomes like powder. This powder solute in alcohol within minutes.
WOW, I never knew you could make liquid solder using isopropyl alcohol. No need to purchase any more Amtech solder now. I recommend to SUBSCRIBE because ERS is sharing over 20+ years of secrets and experience. I just wish these videos were on TH-cam sooner because I could have done so much more. Hopefully I can share some things that will help ERS too. Thanks for sharing!
The smell brings me back to a 1979 audio shop, for some reason all the speakers and audio equipment smelled like rosin, it is how you knew you were in a audio equipment store of the era.
Exactly the old audio cables and boards were soldered with rosin flux because the modern flux wasn't available back then
Hence everybody got asthma. 😂
I love you man, thank you so much for giving us a part of your 30+ years of wisdom
Sorin, press the recessed part of the lid on the flux tin and it opens very easily.
Again great tip! I learnt to solder when I was aged in single figures and have been for 30+ years now but was never really taught the importance of flux, wrongly assuming that flux-cored solder was enough - it's only after watching re-work videos that I recently bought a 50ml bottle of liquid rosin flux which was about 5 quid - it will probably last me a lifetime as a hobbyist, just just like my reel of full-fat leaded solder which I've had since the 80s ;) I might make up some of your home-brew flux to compare :)
Thanks a lot for this! Now i will make my own soldering flux for like no money, 1000g of calaphony in Poland cost 4 pounds, so i will make lifetime stock of it.
Greetings from Poland Sorin! You use Polish Rosin - kalafonia . You have right - smell of Rosin is soooo good :)
Serio? To jest polska kalafonia? :)
great video for beginners in field of electronics! Thanks a lot for advices!
I learned so much watching this. thank you
I have used in the past a mix with acetone and rosin.
The funny part is that some countries has banned already the rosin along with other flux products.
There is the reason "Soldering with lead (or other metals used in soldering) may produce fumes that are hazardous. In
addition, using flux containing rosin (also called colophony) produces solder fumes that, if inhaled,
can result in occupational asthma or make existing asthmatic conditions worsen. The fumes can
also cause eye and upper respiratory tract irritation. "
I do the same but rosin with isopropyl alcohol. Works best when it needs to flow under the chip
I've read on the internet that the rosin used with violins and string instruments (with Alcohol) should be enough.
Is it true?
Its the same rosin as used in the musical world. But what he is buying off of Ebay is actually in Flux form. If your buying the big brick of rosin. You can smash it until it turns into a powder. Then mix it with isopropyl and if you add about 2-3% glycerin by weight. You will have some really good stuff. You'll have to play with your alcohol % but it can be anywhere from 50-80% depends on how you like it.
You know its rosin flux because its in those thin crystal pieces already. But its probably over 80% pure rosin that is why its not a liquid or paste. But also why its not a dry brick or powder.
The rosin flux he shows can't be purchased in the USA. You have to use ebay uk to get it delivered. But you can buy resin all over just find a local music store.
@@yosyp5905 Yes, it is the same stuff. It dissolves happily (but slowly) in ethyl alcohol and isopropyl alcohol. Rosin is a plant gum product and contains organic acid. Some small amount of inorganic acid is added to make mildly activated. With exposure to air, it turns darker (oxidation) over a period of time and loses its activity. The light colored stuff is better.
Rosin with rubbing alcohol works fine, except it drys out pretty fast.
As far as the fumes go, it gets in my sinuses and gives me a headache, so I use a fume extractor. I like the smell though :P
This guy is the best. Nothin fancy just works and works well I might add. I use the same stuff (kalafonia) much better than other more expensive fluxes.
You are right Rosin is the better one solution for soldering and unsoldering everything thanks to his high boiling capacity and properties, but just an advice, I know that the smell is great but is highly carcinogenic!! This is why many people have the fumes sucker or a well ventilated laboratory..great explanation and great video though! P.S. your microscope is awesome!!
in mother Russia we don't buy, we make.........good info !
How to make gold?
@@raymondchan3587 Gold Yeah Yeah?
He is from Romania!
@@gjergjkastro9404 Similar accents means the same place to most of us US folk. 😂
Go to your local music store and you can buy rosin there. they use it for violin or any instrument that use bow...
the quality nis probably better than buying colophon powder (but colophon powder comes in different qualities, whitened, or not ; this is used to make varnish for musical instruments soundboards
I am a simple man, I see a Russian who says "trust me", I give my paw up and click on subscribe. Thanks for a nice recipe for a liquid flux.
He just basically "thinned it"
He's not Russian you ba$$tard
