0.4mm PCB Thickness - production issues

A bunch of thanks guys, we will take this in consideration. BTW, we will not go for the v-grove in the panel (2x8 boards + the extra cut of areas). The board house recommended us to go for braces/hinges, since this thin pcb-panel could easily break w

I did not see any mention on the inner layer setback. We use 0.025" and have not had problems. Point loads with either a CAB or a FKN can sometimes be problematic. I would search out someone you know that has a fancort industries VDP5. This cuts th

Cracked parts close to the edge on pizza cutters are a common problem. There are a lot of stresses on the board as the blade cuts through the board. Raising the blade height so that the boards are not cut clean through will help. You will have to fi

Most likely you have a bad batch of PCBs. This seems like a lamination defect. Most likely, there was some contamination that prevented layers from adhering. You can cut one of the boards at the defect side and inspect the cross-section.

This issue can be common on such large size boards. The newer laser we use today to cut stencils are generally accurate to +/- 5microns X and Y. Probaly way more accurate than your board which will have a +/- into thousands of an inch. Try send a boa

we have looked into a number of depaneling machines and can't justify the cost. what we are trying to do is to eliminate failures due to part stress when employees are breaking out the boards by hand. I heard about pneumatic scissors one day but to
