I have a customer that is having a flux residue problem after wave soldering. Flux is roaring through the board to the top side and leaving a residue. This is only happening on the flat stamped leads. The round leads are fine. They are using Supe

Thanks for the tip! Do you find the boards require any cleanup after exiting the wave with the Superior 420-XF-LF?

Superior 420-XF-LF is what we use. When we switched, it took some time of just running it through the stone before we got the optimal performance. Especially when going into the clean and dry tank on monday morning, we usually let the fluxer run for

Process Flux is AIM 275. Tip tinning flux is Superior 75. We have gotten dual nozzles in the 6mm & 9mm sizes we run. We can get a nozzle to run about 8 hours. Every night we clean all used nozzles with a scouring pad, apply Superior 75 flux with

We are using Superior 515 flux to clean and tin selective solder nozzles. Yesterday the flux turned a bright yellow (like a highlighter) when heated after the flux being applied. This does not happen with our Lead Free solder, only the Lead alloy.
