Ball Shear Test
Review.... ...
-This is a destructive test ( non-reversible process to test the strength of the specimen)
- The purpose of doing this test is to measure the metallurgical adhesion of the ball bond to the die pad
-The equipment used to perform this test are DAGE 4000 with BS500 catridge
BS 500 Cartridge

The procedures for ball shear test:
1. The shear tool has to be placed just beside the ball bond slightly above the surface of the first bond pad
2. The shearing arm then moves the tool horizontally against the ball which eventually pushes the ball off its bond pad.
3. Readings, types of failure modes and pictures of failures are recorded.
