We use a CAB de-panelizer to separtare our boards out of a panel. Works great.

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

How are you sepatating your boards out of the panel? If you are flexing them to break the V-score, this could be what is causing the resistors to crack.

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

check your de-panelling process if you are using break-out tabs or V scoring.
