Hi John, we had one shot with silver coated PCBs. With "no clean" and no changes in process parameters ( we had no input on necessary changes from the boardhouse ) we encountered wetting problems in the first reflow soldering process. Later it was s

You would have to tell us what machine brand you are using, as everyone has his own idea how to recognize X-outs. I find the auto-recognition very time consuming ( non-productive machine time ), unless the camera could recognize an image in one shot

If you really think the vast majority of these are going to fail I think that doing them all in one shot is the best thing. That way, as you stated you only have to reflow the remaining parts one more time instead of 22!! i hope you only have one b

Hello experts, Here is my problem: I have a board that has smt parts on one side and TH parts on the other. We designed special pallet for wave, but the pallet itself is 15mm thick, so we are still seeing some defects. Have any of you tried to find

To be successful, and to yield quality products off any selective solder systems out there on the market today, DFX rules need to be enforced and followed. Lay-out is a one-shot process where as manufacturing of the PCBA is continuous. Obviously, muc
