A dicing saw sounds like a good idea, but be sure it is grounded; consider the potential ESD aspect (FMEA).

At our center, we regularly use the dicing saw to cut all kind of materials including flex and rigid boards. Dicing blade suppliers supply appropriate blades to cut from a plastic sheet to a sapphire wafer. Our own initiative and our customers have challenged us in many ways over the years.

If one side is flat, it should be pretty simple to get it done on a semiconductor dicing saw. This will minimize stress to the components, and a typical kerf is less than 0.01". They use visual targeting. Service houses are available for doing this work.

Use a Fiskars rolling paper cutter, like this one. Do not use the fixed blade unit, as it will tear the PWB:

Hi Steve,
We have a 3 inch square panel of 144 little boards. They have the finest little score cuts I have ever seen.
Each one has a tiny embedded device. I am afraid to break them apart.
Wondering if you can post the pictures, and if you or anyone on Technet has a good idea for how to singlulate the boards.
Thanks,
Guy
