Hi! Can anyone tell me what is the min spacing between PCB edge & land pattern to avoid cracking of components due to mechanical stresses caused while depaneling with cookie/pizza cutter. Thnx!

We are wave soldering some fabs with a lot of unmasked trace area along the edges. The trace area is solid copper covered with tin / lead, no masking, no components along the edges, same on solder side and component side (goofy board design). Inste

Hi all, Looking for some advice on how to run this component through the SMT process or is it always hand soldered? Part number is HSEC8-120-01-S-D-EM2 We are currently handsoldering. aj...

FSW, Another suggestions is if you have rail on your product and you are concerned about stress fracturing certain components you could add a routed slot to add relief in that area. So when you snap the rail off their would be no stress in that area

I have never heard of heating the board for separation. You may want to try some of the following. -Using a roller cutting type depaneler helps reduce the stress. -Using a combination of routing in areas with components near the edge and v-score th

There's no easy answer. It depends on: * Thickness and size of the PCB in the array. * Means of separation. * Type of component. SMT components are more sensitive to the forces that need to be applied to separate the PCB. * Type SMT device. Ceram
