We know nothing about your process, but Kemet ceramic capacitors can be wave soldered. Kemet wrote papers on wave soldering their parts.

We use a FKN pizza cutter and found that even with 5mm clearance and the proper orientation of the part larger ceramic capacitors 1812, 1210 would still stress fracture. We have successfully fixed stress fracture problems by adding routed relief slot

We have a customer that is requesting decoupling capacitors, and we are not sure what they are or where to buy them. I know that the customer wants ceramic decaps. Should we just look for multi-layer ceramic capacitors with the rating the customer

Sorry, I was not clear. I am interested in the strain on the PCB during depanelization using a parallel blade shear. And the effect on ceramic capacitors on the PCB. I was not shearing the capacitor off of the PCB. Regards, Jeff

Our solder irons are tuned to 700*F, but the in-use temperature varies according to the solder alloy and the characteristics of the board and components. Check some of the papers on multilayer ceramic capacitors. They get fairly specific, for insta

I am looking for a industry specification for the amount of strain that is allowable during a parallel blade shearing operation as related to ceramic capacitors. Does anyone know of such a specification? Best regards, Jeff
