Your copper corrosion is not good. It indicates that you have not done a good job in cleaning. [We assume this is a medium green color, not unlike the color of the solder mask on your board, that is almost like a translucent lacquer; rather than th

Currently, in my working factory, we facing the flux residue remain on connector after washing. (of course, this is clean process with WS solder paste). So, are there any ways to clean the flux residue rather than go back to wash again? Because wash

The parameters which effect the problem you are having are flux and contact time try first increasing the flux you are applying. Next reduce the contact time in the wave by adjusting the back flow plate. If the problem is a jig design check out the j
