Hi, ran across a batch of PCB that has white silkscreen during receiving but turns purple/pink after our reflow process. SEM/EDX test can show there is no significant different element between the white and purple silkscreen. Can any help advice what

Hi I have seen some of our multilayer PCBs are having delamination issues even after baking them in the ovens. Does anybody faced this issue before? The problem occured after reflow process and wave solder process as well. The temp profiles are well

Quite sure it is one of the follow things. Squeegees are not tall enough (using after market blades); Are you using a stencil adapter? bottom surface of the stencil must be even with the top of the stencil shelves; printhead assy. is modified, faile

Hola After some investigation I found that these units have this oxide after reflow, so I'm guessing that may be some process related issue, I'm attaching pictures for reference. My supplier has not given me any explanation so far, they are working

Incoming inspection: Look for flaws and measure position of v-score as well as depth. If v-scored on both sides of panel, make sure v-scores are in alignment. Follow the PCB thru all processes inspecting after each stage of processing, especially
