Pr. I agree with some of the above responses. if you are seeing Delam issues with incoming PCB's the following should be check. 1) Check the OEM Print to what Material they are calling out to be manufactured with. 2) If they are calling out for S

50% of seeing it in a single pass. The only time we do this is if we have a board off the line that has delaminated. We'll run a sample of boards through bare to confirm that we have a bad batch. Even if we see no failures on the bare boards, we'l

Hello We are currently cleaning stencils from both process (PbSn and lead free) in the same cleaning machine. A customer is concerned about cross contamination of lead between stencils. Is there any test kit or tool that you can suggest to test the

Unfortunately, IPC-D-279, IPC-TM-650, IPC-TR-464, and MIL-STD-810 will not answer your questions, because they do NOT address LF-solders. Even the tests in IPC-9701 need to be modified for LF-solders, because: * LF-solder has different creep behavior

The FA department is using IPC or J-STD-003 to do the solderability test for the leaded PCB FA qualification. Class A. However, there is no mention of Lead free testing for the PCB bare brd. Can anyone advise whether IPC has release a solderability

When we have sent some of motherboards for reliability testing in a tird party laoratory. It is found that when Dye&Pry is done after 600 cycles of Thermal Cycling, in LGA socket only one of the corner solder joing had 100% type 3 crack. All other so
