In 2001 I assisted the shutdown of two of our company facilities. Very sad day. The equipment distribution was about 75% Chinese the remaining went to Mexico (we were a multi-national CM). I find it amusing that the Mexicans are worried about thei

Rob: We're never heard of paste related problems caused by humidity that is too low. Low humidity is very expensive to control. So, when you think about all the assembly used to be done in the Bay Area. You'd think there would be more talk about i

This issue is not "testability of OSP board". It is "testability of nc flux residue". Kester [or some other flux suppler] can probably recommend a flux residue that is more probeable. We have talked about the problems with probes getting gummed-up

Are you talking about small 'volcanos' that burst through PTH solder connections? If so, you have moisture outgassing through the PTH barrels: * Plating on the hole of your bare board is too thin. It should be greater than 1 thou [25um]. * Your bak

Hello, We want to build in-house cross sectioning capability. I have a general idea of the process and equipment required, but I do not know any brand names to start with. I wish I had written down the equipment model name when I visited our suppli
