[labnetwork] Advice on fine pitch laser trimming services?

[Ioannis (John) Kymissis]

Hello,

I was wondering if there is any advice regarding a service for high
resolution laser fuse trimming - we used to use a service that had an
ESI 9820 system to program 1 micron scale serialization fuses (on a
5um pitch), but that service is unfortunately no longer available.

I'd appreciate any pointers to a service that has an ESI 9820/ESI 9850
or similar system that could handle this small spot size.

Thanks,
-John
