Alternatives to v-score or mouse-bites? | 30 April, 2021

I have a small board in a 5x5 array. Thickness is .014". The fist build, the array was all routed with mouse-bites. Customer doesn't like the edge left by the mouse-bites. Board house says they can't v-score a board that thin. I'm not sure what other options I have. Individual board is 1.5" x 0.5".

Thin FR4 can be routed with a CO2 laser with high quality results, the edge is precise and free of slag. The process is extremely low stress. If the edges are straight you can consider sawing. 0.4mm (0.016") FR4 can be laser routed and sawn at speed up to 100mm/sec.

Can you use a conventional router?

For boards that small and thin, you could also look into punch dies

oooff... be careful of punch dies. They leave a lot of debris and can stress components on the PCB. If you're using them, be sure to verify stress levels with a strain gauge test. Semi-fractured components can pass test, yet eventually cause latency failures in the field.
