RE: wafer laser cutting

All - Remy from APD gave me his contact info to forward on - contacting him directly for cutting services would be the most efficient.

Subject: Re: wafer laser cutting

I've used American Precision Dicing in San Jose for this before. They
have a special laser inside a water jet, which means the cutting zone
won't melt. This way you don't introduce heat damage and more
importantly, the process won't form a melted edge bead, meaning your
cutout will still be perfectly flat. This is important if you want to
use contact masks. The cutting edge will be slightly serrated, though,
as if someone had drilled thousands of 0.2mm dia. holes to form the cut.
