What type of flux are you using today? - Obviously you have already outlined the difference in the parent materials and parent material preparation, so using the same program/profile will not work; the characteristics are different. Try increasing p

Dear All We are using structural similar type of connector in A & B product with same set parameter in selective soldering machine but result in B product is not good. Observation – Plating on A product Connector terminal done on all 4 side But In

I have found the paste flux is the worst. It leaves a black residue that can corrode.

M_, the parts may be similar but the boards look to be different. Is the thermal relief for each lead on each board the same? what is the board finish, HASL, Enig, OSP or other? The part itself may not be your problem but the part that is partial pla

If you could measure and chart 3 variables in my process, what would they be? The boards that I produce are on panels that are 12up and 2x4 up. All boards are single sided paper base w/o plated thru holes. They are on scored panels that measure 7"

I am seeing poor quality solder joints, mostly on 0402 components. The problem is that while the pad on the pcb is getting fully wetted, the solder is not flowing up the sides of the 0402 component, i.e. the 0402 lead is somewhat de-wetting. The re

I have modules that come with a 4 x 2 pin header. The problem is the pins must be oxidized as they do not take solder (no wetting occurring). This occurs whether solder in our wave soldering machine or soldered by hand. I tried cleaning the module i

Try to pre-tin the part. This should give you a lot of answers.

If whatever is preventing the leads on your component from wetting is oxidation, cleaning the component will not help. Consider trying a more active flux prior to soldering. Understand from your supplier the potential complications that may affect
