Bond strength can be measured by a tensile tester. Mount test samples
and pull from two opposite directions. A good reference Book is
Semiconductor Wafer Bonding by Tong and Gosele.

Subject: [mems-talk] wafer level bonding

Hi all!
I am trying to gather some references for wafer level adhesive bonding.
Can
anyone tell me how much bonding strength is good? Or How does anyone
determine good bond stength value?
