Electrovert's corrosion tests show that it's less corrosive to SS than SAC but it still exhibited corrosive characteristics. What they can't tell from the tests yet is how long before the corrosion starts with the alloy. To be 100% sure, Electrover

Ramon: I guarantee you there is corrosion on the solderable surfaces of your board. The issues are: * Flux selected is capable of removing the corrosion at hand. * Processes for applying the flux and soldering the board are effective for the sele

Hi Radek, Thanks for your reply. I use this flux with manual soldering process for the product. Is this flux suitable for manual soldering? or it is only for wave soldering? I have sent the board for analysis, and the report shown that the white res

Things don't disappear completely. If something caused nickel corrosion, the nickel corrosion by-product would be in place of the nickel. Is it possible that ... There never was any nickel? We know that the nickel will diffuse into the copper. Th

Kevin: What was the thinking behind your using a flux that required cleaning �on a post wash assemble for a power switch�? How do you keep the remaining corrosive flux residues from causing trouble [ie, corrosion, CAF, etc]?

Thanks guys. They are seen on some of the pads too. What will happen if I continue to solder them and I got a good solder joint formation? Will the pad continue to erode or corode in due time? or the solder that will recoat its surface will prevent
