I ordered a Bon Pen and need to get liquid flux to fill it. What kind should I get, no clean? rosin? RMA? RA?
So far I used the ChipQuik tacky no clean but it is too thick for the Bon Pen I presume. I also has a felt pen with Kester 981 and it kind of works but the flux feels weak.
If I get a rosin based, what happens if I don't clean it perfectly, for example, under the components? Will it corrode and damage the board?
This is for hobby use at home. My components are typically new, I use leaded solder and I clean with IPA. I want to have just one kind of flux, even if it is a compromise.
