How Do You Measure Solder Mask Thickness MCL

Webthickness for a good solder joint. Normal practice used the average of IMC to represent the IMC thickness. The average thickness is calculated from the IMC cross-section profile. Some have used digital image analysis system to measure the average thickness by taking at least 20 to 40 points of uneven IMC thickness for each sample. WebResistance soldering is done by directing electrical current through the gold cup to melt the solder. The gold thickness of the gold cup terminals was not controlled very well, and some had much more gold than others because at that time there were no good methods of ensuring just the right thickness of gold; we did not have XrF or any of the ...
