Amtech NC-559-V2-TF No-Clean Tacky Flux USA (30cc)

Product Information

tl;dr What no clean lead-free tacky flux do you use / can recommend for hot air rework of the usual suspects (QFP, QFN, SOIC, small BGAs etc.

Get one that doesn't claim to be genuine amtech; you will have less chance of getting "fake" nonperforming flux. The only time I use extra flux, is when I'm forced to use old components or boards which are badly oxidised.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.

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.

Another thing you can do, if a part is oxidised is clean it first with abrasive paper, then it's normally possible to solder it using rosin cored solder and no additional flux. 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. It has a good in and out of fridge shelf life of 24 months and says in the datasheet REL0 which is meant to be resin based and halide free. RetroSix is a small team of people who have been in the gaming industry and retail business since 2013, and sold consoles, controllers and even designed our own controllers and consoles.No-clean rather means that the flux can be left on PCB for several consecutive SMT assemblies, also won’t cause corrosion if left indefinitely.
