Yes, unfortunately I was alerted to this problem at QC. (which is a reoccurring issue)

Check out the set up of Depanelizer. Try to cut at slower speed & check the blades to make sure it is not time to resharp the blades. If all this parameters OK I would sustect lamination process of board house.

Can you cut v-scores deeper to resolve the issue then build carriers to support the panel? I would say that we usually build carriers for anything that thin regarless of the depanel method.

We had a similar problem once, it was due to insufficient v-score depth. While waiting for remade PCBs we would run an exacto knife along the score lines prior to depanel to cut a little deeper. Not ideal for sure, and not fast, but it worked.

Maybe the V-Score is not deep enough? I am used to seeing more like a 30% remaining web, you are closer to 50% 'hege

Deepening the V-scores was in vain. No change. This board is on Rev R now, with no changes to material/array/v-score spec, and this is the first we've seen this problem. I just don't get it.

We have a small board about 1" by .5" and it is .012" thick. It is in a 50 up panel. We have tried rat bites and v-score and we keep seeing delamination around the edges. Anyone have experience depaneling boards this thin?

Incoming inspection: Look for flaws and measure position of v-score as well as depth. If v-scored on both sides of panel, make sure v-scores are in alignment. Follow the PCB thru all processes inspecting after each stage of processing, especially
