Hello Loz, Blue residues on circuit boards can be caused by copper corrosion, component body deterioration, marking permanently, and adhesive break down. In this case, a more subtle mechanism appears to be possible. This is a no clean application

No, none of us can tell you what is the acceptable level of halide content or contamination in flux residue. The level of harmful residues on your product helps determine the reliability of your product. We know nothing of your product, its custome

I use adipic acid to clean our Ersa selective solder machine nozzles. Makes a huge difference and is quick and easy.

Guys, thank you for your advice about Adipic Acid, it's an amazing! In my country one small box of Hakko Pretinning Solder paste (FS-100) costs USD30, 1 kg of this axid costs USD5.5 .

OK guys, we got our Adipic acid. What is the preferred methode of applying it? a) Nozzle mounted, momentarily turn off wave and then brush? Or b)coat nozzle with the acid then mount it and turn wave on? By the way, we are using Indium flux WF-994
