Sample Requirements and Preparation

No special sample cleaning is required prior to wire bonding.  Sample metallization must be thick enough to withstand the rigors of bonding.  Samples must be securely mounted in their respective packages, and the package must be securely mounted to the bonding fixture.  Double-sided cellophane tape is not an acceptable mounting technique.
