| What are the factors that go into determining PCB Board temperature requirements for the Wavesolder process? Most of the recipes I've seen call for preheating the PCB to around 230F - 250F. This temp is about 210F - 230F below the typical solder te

| Dear all, | | What are your views on reworking BGA's? I mean, with the BGA going through reflow temperatures four times or more, and with a manual reballing process, wouldn't it raise up a few reliability issues? Would you consider not doing rew

| Is there any problem using SMT on gold boards? 15 years ago we were told not to use gold boards, but I can't remember why. Judging by the other postings it now appears to be common. Only problem I see is that the nickel should be plated, not ele

| We have mixed to negative feelings about Omikron, but I beileve it is due to problems with the board fabricator rather than the process itself. When done properly, our Omikron boards have had very good solderability. However, we have had several
