When a hole is drilled during board fabrication, it can transfer resin from the base material (eg, FR4 core or prepreg) to cover the exposed edge of conductive material in the wall of a drilled hole. This is called resin smear. Etchback is a control

Hi CW, Larger chip caps can be susceptable to cracking, but mainly this is due to handling - flexing of boards is the main culprit (the part being mechanically joined at both ends to the board). PCB's usually flex easiest along one axis, and larger

Hi Liza, several years ago we had problem like that only with Carrier Tape made by Ploycarbonate material and by using High Speed pick & place. Very few pbms met by using low speed P&P machine. Problems have been solved by using Polystirene Carri
