Making a high-quality Flux applicator.
A 2 in 1 White-Out bottle makes an excellent flux applicator tool.
These bottles have a spring-loaded metal point that seals off the contents when not pressed.
- clean out the old white paint with IPA.
- cut off the applicator brush at the location shown.
- rinse bottle and cap with Varsol.
- once again, clean the assembled unit with IPA until no white is seen in the alcohol.
Let dry, then fill 3/4 full of liquid flux.
You can easily apply a single drop of flux to the location needed or run a bead the length of a trace.
Make one of these for IPA and oil application too.
I was hoping this would be a good applicator for solder paste but the paste is too thick to work in this setup.
