Hi Ramon, It's been quite a while since we did this but to the best of my recollection (it's tough getting older)I believe we applied conformal coating to component ID after reflow and before any wet processing.

Hi Kenny: Didn't the CC discolored, or better yet darkened after the reflow oven? I ask this question since the baking temp for CC is a lot lower than the reflow temp. I am all for it, if it works. I am just curious.
