- AMTECH has dominated the flux market - and for good reason. Some new product launches have changed EVERYTHING. See which flux has now claimed the title for greatest flux, and a new flux which I'd like to add to the table.
These recommendations have been made after using each product for over half a year, and professionally on customer motherboards. I was not paid in any way to make any video, and all products were purchased full price.

The majority of comments on my last video, the BEST Hot Air Station for Budget Microsoldering, were on the flux I used. After a couple months, THE FLUX WENT OUT OF STOCK. So, I of course, was freaking out. I tried all sorts of fluxes, and found the Ugain to be a fitting replacement. Later, TCRS Circuit launched Citriflow and got me curious enough to try both the PRO version (much more liquid) and regular (thicker).
Thank you for your time, and if your still reading this long description, I don't know where you are in microsoldering, but I do know there's a threshhold where you can get so good in fixing phones that if YOU can't fix it, NO ONE can - and if that's where you're striving to be, I wish you all the best. Also, your really attractive lol.
The reason for the flux not stopping after the plunger is released is the air inside the syringe trapped above the flux. By pressing the plunger you compress the air and that's what's pushing the liquid out. You release the pressure on the plunger, and the air inside decompresses, but not completely, as it can't move the plunger any more to an equilibrium due to friction. The remaining air pressure pushes the liquid out until the pressure equalizes. The same thing happens with CA glue, ointments and other stuff in metal tubes - the remaining pressure is not enough to spring the metal back to equalize the pressure.
By drawing the plunger back you actually introduce more air into the syringe making the problem even worse.
What you should do instead is to store the tube vertically for some time, until all the liquid migrates to the bottom (towards the plunger), and then push the plunger until all the air (with some remaining liquid) is gone and the liquid starts to come out.
In some cases there could be a stable dispersion of air formed in the liquid itself. That could be dealt with using some heat (to decrease the viscosity and release the bubbles) or with a vacuum pump which will expand the bubbles and increase theirs buoyancy.
Omg thank you for such an insightful comment - I’ve tried what guy said, and it works! I also reached out to the company, and they’ve changed the plunger to be just like Amtech now
Here in down under, we do not 'sodder', we 'solder' :P
For our repair shop, there are different things which count:
- Non-conductivity
- Viscosity (especially with heat)
- easy cleaning
- health risks
So your test might not be representative for all people.
Great point - this is absolutely true. The TCRS flux definately meets your criteria:
- Non-conductivity: th-cam.com/video/GSj3aUOE5CU/w-d-xo.html at 55 minutes, you can see both Amtech and TCRS have extremely low conductivity.
- Viscosity: There's both the pro (liquid for CPUs etc) and regular (thicker) - so you can find which viscosity suits your needs.
- Both clean extremely easily, one cotton ball and alcohol is enough to clean flux used on a BGA area on a board.
- Health risks are addressed in the safety data sheet here: www.tcrscircuit.com/sds
Thank you for bringing this up, hope this helps.
@@HarryKwastaken Wow - thank you :)
After 1 year Finally! i thought you're uhm . . anyways, smooth video, definitely true about the UGain Flux, been my day to day flux 👌🏻
Exactly! And yes, I was uhm . . Hibernating.
Bro you need to make more videos!! Looking forward on Budget vs Hakko Weller comparisons
Thank you so much! It's kind words like these which keep me going - I'm uploading a video on huge changes to the repair economy on February 1st, maybe you'd be interested!
Eevblog did a very detailed budget Hakko/Weller comparison.
TCRS is the best of the best. The sponsor is TCRS... 🤣🤣🤣🤣
Haha, I wish that was true! I actually wasn’t payed for this video, and bought 2 tubes with my own money - and if I was paid, I’d have to disclose it legally. TCRS have been really cool tho
@@HarryKwastaken Sure. That was a joke. Honestly most of repair workers browse through heaps of cheap aliexperss bs hoping to find good flux. All the branded gear is cool of course and works magic but hella expensive. I myself was always using IPA rosin solution for bga and 559 for other stuff.
Nice comparison video. Though I personally just use whatever I can get for cheap at my local brick and mortar store. I mostly do just simple repairs for friends and family and the cheap stuff is even enough for the bit of microsoldering I do...
Yeah, absolutely. If it works for you, then it’s fine.
Great editing, love your videos
Thank you! I appreciate your time
hey so im looking to replace the 5g antenna on my iphone 13 pro and the youtube video says to use flux is it a certain kind of flux i need to use or no because i have oatey no.95 lead free tinning flux is this right or no?
@@xaviermacaluso If it’s the one that connects to the underside of the motherboard, it doesn’t need any special flux. As long as the flex cable connects to all the dot-like connections, there will be no problem
In one of the sequences, you'll see the process of soldering an apple watch flex cable!
You definitely need to make more videos
Just wait a little longer - by the end of the month, there will be some huge changes to the channel
You just missed something really import - the ease of cleaning the residue
I’ve tested both, and cleaning is super easy - like one swipe with cotton and alcohol cleans most. Thank you for pointing that out
What about SD360?
You don't just buy weird tins of brown hard cake from Poland for 1€ and dissolve them in isopropyl alcohol? Got it from Sorin at "Electronics Repair School". It does have some advantages, but overall i can't decide whether i love or hate it, certainly both sort of.
Also i never understood why Amtech, it's not like other big ones like MG and Kester and Chipquick don't make decent flux? And then half the people end up buying fake Amtech which is just... well the outcome predictably varies.
Brown hard cake (maybe you mean rosin), very interesting. Amtech became famous because of its long-term resilience to oxidation, but the fake flux problem is what deters many people.
@@HarryKwastaken Even that in those tins isn't pine rosin as-is. It's somewhat distilled and activated, so it is a real electronics flux, it's just fully concentrated down to a solid with no solvent left.
Does it create a lot of fumes? and can you use it in like a rosin pen to find shorts?
@@HarryKwastaken I don't have one of those evaporator heads yet, but i do suspect that it can be evaporated just like raw tree rosin. It is fumey but not terribly so, and it doesn't smell burned easily. Most stores here sell Bienenwohl Löthonig for some reason and that's just bad, stinky and smokey, i don't even know why it still exists.
TBH i usually use NC-559-ASM-UV clone flux.
Great job, Harry. Also your editing, made the video so engaging to watch. Were wondering if we could do something fun together in the future. Any chance can us reach u out:D
Thanks man! I'd love to talk, you can reach me at passionhdwastaken@gmail.com anytime.
Choosing soldering fluxes that you use for hi-freq microelectronics by only smell and flow is like choosing car only by color of interior. Google for "surface insulation resistance test" and then ask yourself: why Ersa, Martin or EFD FluxPlus costs FROM 20USD and up? th-cam.com/video/UCemeyS7EVw/w-d-xo.html
now compare solder flow !
Right on! I haven't noticed much of a difference in how the solder flows in both - but mainly how long it can keep solder flowing. Some cheap rosin sucks at making solder flow, but these 2 are good enough for something like HDMI ports etc with small pins....
Out of stock. :(
