I use a pizza cutter with parts closer than that, but they are small-ish (

Wonder why do you need to do this transition? Pizza cutter is pretty simple to use and maintain.

V-score cracking components

We used to affectionately nickname our "roll blade" equipment.... A very technical term.... THE PIZZA CUTTER!

Agree with Cmiller. We had a similar prob. with some caps. on a v-scored array. We bought a pizza cutter depaneliser and the problem reduced. It's a "FKN Systek" if you want to look at models.

Min spacing for land patterns from PCB edge

Hi! Can anyone tell me what is the min spacing between PCB edge & land pattern to avoid cracking of components due to mechanical stresses caused while depaneling with cookie/pizza cutter. Thnx!

Here's what we suggest: * Keep a 5-mm space between a board edge and a ceramic capacitor. * Mount the capacitor parallel relative to the edge. * Design pads about a half of the termination. * Fixture the board when using your pizza cutter.

Is this what you are looking for? We do this on quite a few boards and it has eliminated component problems from the Cab depaneler (pizza cutter)

2010&2512 cracking

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.

Depanelling scoring groove PCBs

We have several, the one everyone likes is a Fancort VPD5-330. We were having trouble with cracked ceramics near the score line with our pizza cutter style depaneler. The linear blade made it go away entirely. Not the cheapest, though.
