This is no joke *if using leaded solder* .
Leaded solder is very safe under normal use but not if you aerosol it like this. You'll certainly breathe it in or swallow it over time. Even tiny amounts are dangerous this way.
Shave the solder bar in a bucket under some liquid, let the liquid evaporate and then mix with flux.
If using unleaded do as shown here with no problems.
It’s probably lead free
this paste is very thick. is it possible make it less thick to use un syringe
I had thought about this same idea but never tried it. I wondered how good it would be. What would its shelf life be? Too bad you did not show a demonstration of using this home-made soldering paste.
Thank you for this video, I am now more intrigued to try it myself.
that was my first thought at the end, was "why not show it in action" and I am guessing it's because it does not work very well, I tried this with something that solders very easy, with just rosin flux, Bismuth, but when you break down metal like this it gets oxidized and that contaminates the whole process bad, This would probably have to be done with an ultrasonic device, under flux based on rosin and alcohol so you get fluid movement initially, and add some sharp hard steel or other magnetic material chips so you can extract them afterwards leaving just chipped up metal in flux that was done under an inert environment of the alcohol and rosin dissolved in it, then you can let the alcohol evaporate to the thickness you want, so it will still dispense, something else I doubt works for this, using that needle on the tip, but with the tip removed so its just plastic hole larger than the needle's then maybe, it will flow out when plunged
I did the alcohol trick but using xylene over aluminum chips to powder it while keeping it oxygen free and it boosts rocket powder drastically but you have to keep it wetted down by oil once you add it to something because the powdered aluminum from ultrasonic bashing it in xylene once dry will explode it is so flammable leaving nothing but alumina (powdered sapphire or aluminum based glass powder)
I think this work is very harmful to your health. I recommend buying a commercial solder paste.
You are right. Never ever grind solder to dust inside a closed room! You will contaminate your workplace an the air you are breathing!
Cool idea. However lately I have been watching some videos from people who claim it is better to do drag soldering and not use paste at all. Goes a bit faster maybe. I have just put a soldering station on my wishlist. When I order it I can try this for myself!
Good vid, should have given a final test demo of the product maybe, thanks for sharing
There's a reason he didn't.... The amount of force needed to push such a thick paste threw that needle is going to make this unusable. Odds are the twist lock needle blows off before the mix exits the needle. This is not even mentioning how this will act to solder items when contaminated with filings from the sand paper are now mixed in with this.... I personally would not recommend this for any job where you NEED SMD solder.

@@2112user Yeah. that was my first thought....jamming the needle - but for a home hobbyist I'm sure it will do the job. The solder isn't in 'ball shape' and the ratio probably isn't right, but I'm sure it'll work.
Didn't show it because it's probably crap, no balance, oh just little bit of this and a little bit of that, should have put some scrapings off his wife or girl friends pants that makes it go faster :-) ooooh sick mind I have but it takes all sorts :-)
Solder paste is dirt cheap so I can't see the point unless you run out at a bad time.... A brave effort mind and I can't see why it wouldn't work just fine apart from the fact solder paste is made from tiny balls to help with the reflow... Was fun to watch...baz
Buenos días, puede funcionar pero pienso que las partículas de abrasivo del tambor de lijado del Dremel tienen que contaminar el producto del lijado y por ende la pasta, voy a tratar de usar una lima para evitar ese problema.
Me imagino que el flux líquido es a base de resina vegetal, la uso bastante y tengo un flux en pasta bastante viejo pero que es excelente.
Excelente. En lugares como chile esos productos solo los encuentras en santiago. Puede costar 5 dolares pero el envío te sale 15. Prfff.
A idéia é boa, porém acho que uma lima rotativa teria um resultado melhor, pois com a lixa fica resíduos dela na pasta e com a lima você poderia tirar o resíduo com um imã, caso existisse. Abraço.
Alberto esta genial este método, una pregunta donde conseguiste tu equipo de aire caliente o que marca es?. Saludos ¡¡¡
whats in the brown bottle, I like what you have done, also you should have a list of items used and just for all the others, " it's late at night and you just starting to run out of solder paste what will you do , and you really want this job finished ' ...CHEERS lUIS THANKS FOR THE TIPS

I'm all for shoestring/make-do approaches, but if you had to purchase a tube of flux anyway, why not just purchase a tube of solder paste? In the quantities hobbyists use, even fancy professional-grade silver pastes aren't prohibitively expensive. Failing to see where there are upsides to this approach, especially considering how much worse it has to be to work with compared to a commercially-prepared paste. (Inconsistent solder bead size and contaminants like grit from the grinding wheel are two potential concerns that spring to mind.)
I completely agree with you. It's even worse than what you said.
He's using fake Amtech solder flux from china, which is sold for about 2$ for 10cc. (and most of the time, it's not even solder flux, but Vaseline...)
While :
- XG-50 MECHANIC Solder paste cost 2,8$ for 35g. fr.aliexpress.com/item/XG-50-XG-500-35g-MECHANIC-Reparing-Solder-Soldering-Paste-Sn63-Pb37-25-45um/32799816881.html
- XG-Z40 MECHANIC Solder paste - Seringe 10cc cost 2,8$ fr.aliexpress.com/item/XG-Z40-10cc-MECHANIC-solder-paste-tin-cream-solder-flux-For-Soldering-Welding-Repair-Rework/32652255777.html
Doing this is :
- A waste of time
- A waste of money
- Health hazardous
As I watched the same thing came to mind. The contaminants from the dremel sanding drum and the oils off the fingers will absolutely degrade the quality of the paste and will make a less than suitable solder joint.
ABSOBLOODYLUTELY Bang on!
THANKS
Great, thanks for your cool idea
Sn and Pb in your hands... I do recommend safety mask and gloves indeed. From a chemist.
What is the name of medicine tar like water?
Genial! La próxima vez informa de los componentes usados, de hecho, que liquido es el del frasquito negro con tapa azul?

What else can I use if I don't have any soldering flux
At least can it come out from the needle's nozzle?If this method is efficiency there are solder bars that used in soldering baths.These are much easier to grind them in bench grinders to make your own soldering paste for a life time every time you need it.
for it to work well it need to be solder balls and not shavings
Nice!
Nice work bro✌️
Hmm ... I'll just buy it.
Witam co to za płyn w brązowej buteleczce ciekawy pomysł ale wolał bym uzyć gruboziarnistego pilnika z tej tarczy mogły dostać się opiłki ściernicy pozdrawiam z Polski
To był topnik w płynie, w Polsce można to kupić pod nazwą RF800.
Can you tell me where would I purchase soldering paste mix and liquid solder flux, Many thanks
Temu
Never ever grind solder to dust inside a closed room! You will contaminate your workplace an the air you are breathing!
Muito bom trabalho. Serviu bastante bem
Vo do likvid ka name kya he vedio me bahut chhota writing he kuchha malum nahi pada.please reply nice idea
Good idea but I I would like to see you put it to use
Why don't we sand the soldering wire itself without melting first ?
You should give us a demo. But anyway nice idea. Like and comment
is it really worth it if for 1.37$ you have 16g of this paste?
U r the man i m looking 4 bro hats off to u 👍👌
Grinded Solder plus sandpaper plus solder paste equals soldering paste
Thanks.
Solder paste is only $5. Did this DIY solder paste work?
there is NO WAY the thick clumpy shit ever got out of that syringe !
it was easy ... thank you
thank you for this video , really informative
Great job tx bro
Many thanks.
Kivli MakYahweh
wow
What guage needle is best?
USE IT IN HIGH DENSITY SOLDERING ??
Следующее видео - как из пасты наплавить припой.
just wondering, with so much paste and flux, will this dilute the solder and hinder conductivity?
As you can see, it works !!!
the paste and flux will burn out with the temperature soldering and all that is left is solder, and a mess but it will be a solid joint!
great video , which kind of matter do you use
*Ce serait bien de connaitre le dosage des différents ingrédients, çà doit être important quand même.*
Why not just buy solder paste for 5 bucks?
YOU ARE RICH MAN BUT I LIKED YOUR VIDEO
Very good
Just out of curiosity i looked at google images for similar looking solder rolls, i found 6 potential brands, all leaded...
Might wanna not wanna grind up lead, not particularly healthy to breath in
Muy bueno pero faltó que lo usaras amigo.
Muy bueno tu video!!
muchas gracias, por favor ayúdame compartiéndolo
omg that is proooo
good man ❤️️❤️️
👍👍👍
Oh my god solder paste with sand paper dust?
by such soulder you can print flexible pcb on paper with conductivity and flexibility
Arjit Singh how?
This is meant to be soldered anyways
no , u still need Photo paper with Laser printed circuit on it
Not fine enough for me, does not work.
Good But where should I get liquid flux
Guess where... In Home Depot or any shop that sells soldering equipments ;)
Ok, don't worry, you can do it at home if you have some muriatic acid (HCl, HydroChloric acid). But it doesn't worth it I tell you. You can clip some tiny solder pieces that fit the part you want to solder and use a tiny heat gun on it, mask the part with cardboard that you don't want to burn.
You need to use A LOT more flux. Solder paste is mostly flux with just a tiny bit of solder. For that amount of powder, I would have used the entire syringe.
Can you upload aplication video ? how to use.
Turn off audio when watching and speed up.
How to further...should have shown in video
After all that you don't even show yourself using it?
can literally buy this stuff for one dollar
You know, India is big, most people watching such videos are far away from any store and most likely they are poor. That is the reason why this vid was made, I guess.
Plus money isn't the only measure of value. Knowing how to make stuff is greater wealth than that.
@@NavinBetamax
Ok, I thought this guy is an Indian living in India, could you forgive me please?
so they don't have money for solder paste but have money to pay the internet bill?
In a pinch I would probably do this as opposed to wait for delivery. Nothing the home hobbyist does is mission critical rocket science.
Great video , would be better with narration .

agora use essa meleca, isso não vai passar pela seringa
Kiddies, dont try this at home. This is a waste of time and potentially quite hazardous. Hand solder, or buy your solder paste.
Are you from Colombia?
No, I'm from Mexico
@@laborjag the project you make its work or not
@@pak_eco_420g3 it works
No
what kind of heat gun is that?
aoyue 8034
Beretta M9
what is the green paper in the background called?
think it's a cutting board you buy in stationery store.
sholimz thankyou
The name is Green Cutting board or green cutting mat. google will show you the correct picture.
VERY INTERESTING YOUR TUTORIAL AND TIPS THANKS ´.:AGUSTIN HEREDIA
Maker Paste would be so much easier!
i bet if you add up the cost of everything including the overuse of the Dremel and how often you have to change out sanding bits that will get clogged, not to mention the time wasted on grinding for 800x speed for a ~1:20 with 2 cut scenes ( i know that it probably wasn't that long but my hands get numb after grinding like that for more than 5 minuets)
now buying maker paste or any of the other brands (even the cheapest) you will get better quality and time/cost efficiency
Reason for expensive repair rates
Ok klass!!!
Ok but why?
In the factory, on PCB boards with surface mounted devices (SMD) (as opposed to 'through hole'), the correct technique is to apply a thin layer of solder paste through a mask with holes that are only in the positions of the components (like silkscreening) . Then a robotic machine picks and places all the components in the correct positions, and the board is baked at a specific temp until the solderpaste melts and solders everything to the board automatically. You can approximate this technique at home with a hot air gun, toaster oven, etc., and waiting a month or 1.5 months for solder paste to come from China can be irritating. Sorry for the long answer but you asked 'why'.
3:25 what's the machine called
Hariharan Magendran that is a Dremel
Wasted time of life 🙄🙈, order solder paste better from Banggood etc.
why should you ever do this......... ??
general knowledge, and there are some countries that are difficult to get or are too expensive, there are already two comments about it
