What happend yesterday (06.August.) that Netscape isn�t good anymore for viewing the pages of SMTnet? Same thing with Apple computer and Netscape. Had to find someone with MS explorer installed to get this out. Hope it�s not a discrimination or somet

I have seen a few references in this forum to an old study (1980s?) by Roger Wild at IBM. But I cannot find a published report or usable reference to one. davef mentioned the SMTnet archives as a possible source, but that has also been a dead end.

It seems to be no solder paste release at certain stencil opening, you may need to enlarge the stencil opening. By the way what is the area ratio for the opening and how is the shape (round/square/diamond)?

OK, POP already done, and you are mounting the POP device. You are seeing opens. Opens at the device/PWB? or opens at the device/device interface? Or possibly both? 'hege
