white dirty solder



white dirty solder | 13 January, 1998

I have a problem! The solder on my pc boards look great comeing out of my reflow oven. They go thrue the rest of the prossese and at the end at the qc station it's cold or whitish or gray not shiny. does any one have a idea on how to correct this problem. The production manager says that its a smt problem but when the boards come of my smt oven the qc says it looks great. I think the problem is in the washing proscess,or the flow solder area.
