Test Fixture with Sintered Connections Between Mother Board and Daughter Board

摘要

A test fixture includes a mother board that has test signal lines configured to couple to a test station. The mother board includes a recessed region with contact pads coupled to the test signal lines. A daughter board is engaged with the recessed region such that a top surface of the daughter board is approximately coplanar with a top surface of the mother board. The daughter board includes test signal lines coupled to contact pads on the daughter board. The contact pads on the daughter board align with the contact pads on the mother board and are permanently coupled by sintered bonds.
