Hello Tech-Net:

I am asking for suggestions as to the best bare board tester that can be
purchased for high density SMT designs.

Design rules include 1.5 mil SMT pads and 3 mil pitch.
Volume is low.
We already have a flying probe but want to add a dual access test fixture.
Direct IPC 356 net list down load is also required.

Suggestions of where to go (and what the pricing might be) would be most
appreciated.

Thank you
