The activated residue is clear and non-corrosive - can be left on board for multiple SMT assemblies (manufacturer recommends cleaning all flux residues at all times to avoid board contamination or voltage leakage on circuits with high impedance, also non-activated residue may absorb moisture from the air and subsequently cause corrosion). Sure, not strictly necessary for any soldering nowadays since any half decent brand of solder will have rosin cores anyways, but it really does make SMD soldering easier in my opinion. Fully translucent thick rosin-rich solder chemistry leaves clear residue easy to evaporate with hot air, cleaned using isopropanol, industrial solvents, ultrasonic scrubbers, or vapor degreasers. VS-213A-TF retains all greatly admired AMTECH's no-clean context - industrial wetting capabilities, optimal tack/viscosity, long lasting performance, clear residue, easy cleaning, and signature AMTECH pine scent.

If you've created a bridge, need to solder a jumper in a small area, or are reflowing a chip to try and remove corrosion - good flux will make your life easier. The only thing that annoy me is, where to get the "piston" for them - Have to use a screwdriver to push the gel out of the syringe. Currently I'm using EDSYN FL 22 R for normal soldering of THT, but from its dark color it appears to have quite a lot rosin in it.

Putting that expertise to good use, we decided to start RetroSix; a small team of people passionate about retro gaming, and restoring original consoles to like-new, adding our own twist and style to them and in general bringing a modern twist to retro. edit: ehhh it's conductive even when non activated, check comments below for more details, I probably wouldn't recommend it knowing this. We believe partnering with other likeminded companies is a great way to help each other out and ultimately make products that are better for the end consumer.Since you use Chipquik SMD291 try and reproduce the test in this video, it may be counterfeit flux being used as the label appears backwards and marked differently. And food-grade alcohol is cheap and we always have some in the house on account of familymembers using it for making their own limonchello and such. Syringes are intended for industrial dispensing machines and use a piston stopper instead of a plunger - do not remove the piston as it delivers the best seal to prevent contact with air. I've always found this chinese "amtech" stuff to be pretty good, but of course there's no assurance that one batch is the same as the next. Any partner we work with, parts, tools or consumables adhere to high standard in product quality, safety and sustainability, aiding and helping to progress the industry to keep devices running longer and assisting the repair industry.

Only downside is that it gets really sticky, so I almost always have a bit of alcohol close-by to clean up my tweezers after every few components. DIY soldering flux, get an IPA and mix with violin's rosin as its already cleaned and filtered, all of these ingredient are cheap and easily sourced. I wanted to share with you the information that you will read below, so in case anyone in the future decide to visit topic by trying to 'hunt down' an amtech distributor in europe, he can find this topic and 'this post' and read it. I'm looking for a tacky flux, something like Amtech, but can't seem to find a decent seller anywhere in Europe. I stopped because I'm a goody-two-shoes and we had some hazardous substances law come in and I couldn't be bothered working out what might be required (not like I'd ever be able to get legit documentation for it anyway).By rejecting non-essential cookies, Reddit may still use certain cookies to ensure the proper functionality of our platform.
