| A buddy of mine has problems after depaneling double sided pre-scored PCB's. Resistors near the edge, after put into the slice and dice machine contain micro cracks. He's checked for them before and after depaneling. We figure it is the sectioni

Is anyone presently using a laser in depaneling their PCB's? What OEM's equipment are you using? What advice would you give regarding laser cutting pcb?

For connectors, we maintain a 0.05" clearance from components edge to the center of the V-groove score

Hello all, I am about to design a panel and there are two connectors on the board that seem to be very close to the edge of the board. I am worried that they might interfere with the cutter blade. Can you tell me how close do you think a part should

I represent Fancort Industries. We provide "pizza cutter" and horizontal opposing blade "guillotine" style v-score depanel equipment. The edge clearance requirements are 0.030" - 0.050" for the wheel cutter and down to 0.020" for the opposing blade e

A word of caution: thick webs (i.e., shallow score grooves) can result in scrapped boards, especially if you've got the dual-wheel-type score breaking machine. I discovered recently that shallow score grooves, combined with DULL knife-edge guides on

Hello, does anyone have any information on stress induced during V-score depaneling. We are using a machine with a fixed blade on the bottom and a free rotating blade on top driven by a motor. We have had some cracked capacitors on the edge of an a

One problem you may have with deeper scoring is not so much broads breaking apart unintentionally, but warping upstream while on the SMT line which can cause sagging. This may give you transport issues from one machine to another, and if you have an
