The question- does anyone have a good repeateatable way to test the
bond strength of heatsinks?

Background- We are manufacturing an .062 six layer board with an .062
bonded heatsink on one side. The board is SMOBC, thermal cure matte
finish mask. Our current method is pressing on the sink and board
junction  to try to separate them manually. This is the same
method our customer uses. This is not very repeatable or
comunicatable. Any ideas out there?
