However, my feeling is that the dye color is a minor constituent of the coating material, so the electrical differences should be minuscule. However IR solder reflow should be really affected by the mask color, most differences I would expect between shiny white and matte black. | |

This was brought up as a possible defect source in the context of QA. It sounded like BS to me at first, but like Tin whiskers is one of those corner case things that might conceivably be real in the right situation and set of conditions. I guess this question is more about the dye chemistry used to mix this stuff | |
