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.

I have seen resistors cracked during placement. The part was programmed incorrectly and the nozzle pushed down on the part too hard. I do not remember seeing any cracked during depanelization. Nibblers can cause damage if they are on the bottom and

I've seen crack on resistor also.The crack on ICs mainly is on the solder joint due to very high strain.

Hello, I have been tasked with finding a solution to rework 242 boards that have 34 incorrect 0603 resistors placed. These resistors are placed throughout the board and are surrounded by other SMT components. If anyone can advise me on a more time

We experiences some failures on PCB assemblies from the field when a methacrylate epoxy adhesive was used to secure some through-hole components to pcb board as reinforcement against vibration. During application, the epoxy covered some smaller SMT c

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

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

Guess the better question is why are the resistors and FETs heating to the degree that they discolored the coating? If the coating is discolored, I'd be concerned with the possibility of cracking as dave mentioned. Cracks defeat the purpose of the
