Continuing, I�ve optioned about the uselessness of shear testing of solder connections on this forum previously. So, the points that you make about the elusiveness of developing a standard for measuring solder connection strength is well taken. I�l

Nice to have you back on SMTnet. Some of the newer folk have missed-out on the solid contributions you�ve made to the Forum. The chicken wire cleaning basket was a classic!!! [It�s a shame that the folk at SMTnet can�t recover those files.] We bu
