95%+ of my boards are small and therefore are panelized using the V-score technique. Getting a lot of resistor cracking even though the resistor is layed out to be perpendicular to the long board edge. What dimension should be used from the board e

We had this same problem several years ago. The caps and resistors were cracking when we snapped the boards apart. We now use a pizza cutter style depanelizer. A couple of manufacturers that I know of are CAB and Fancort. I hope this helps.

To prevent cracking SMD components near the edge of PCB you should use guillotine for V-cut groove. Other solution is redesign panel of PCBs and in critical areas you should mill along the outline instead of V-cut, but if you choose this way probabl

Hi all, lately ofen I have problem with cracked ceramic capacitors.We use 0805 and 0603 cap. Samsung.ICT measure diferent capacity of nominal.If I tray to desoldering component , then component cracked.I think , that the reason is the moisture in com
