Chip wire bonding
WebWire bonding process is the key driver of the package assembly yields. Proper optimization and process window development for wire bonding is essential to minimize nonstick on … WebWire-bond Connections Avoid chip-to-chip connections – Unless electrical performance demands it, wire bonding directly between ICs should be avoided. Creating the stitch bond transmits mechanical energy to the pad, which could lead to micro-cracking in, or under, the pad metallization.
