Can any one help me with a solution to this problem, we have recently experenced board failures because of a contamination across various sm capacitors which first looks like a splat of black paint which run diagonally across the cap, under a microscope it looked like fern leaves. Our boards are wave soldered and w edo not clean after solder flow.
