What it is

The West Bond wirebond-R1 is a manual wirebonder used for making electrical contacts between semiconductor dies and packages. The equipment is a West-Bond Inc. model 7476E.[2]

How it works

The West Bond wirebond-R1 makes electrical interconnects by wirebonding between an integrated circuit die and an integrated circuit package. The tool supports standard 45 degree wedge bonding and 90 degree wedge bonding for deep access.[2]

The West Bond wirebond-R1 is optimized for Au or Al wire with a nominal diameter of 25 μm. The tool is compatible with Al and Au wires from 0.7 mil to 2 mil in diameter for room temperature thermosonic bonding, and it uses a 4 W 63 kHz ultrasonic transducer with manual control through an 8:1 reduction ratio micromanipulator arm.[2]

Where it fits in the process flow

General reference — not yet source-verified

Wirebonding follows processes that prepare the die and package for interconnect formation. The resulting bonds provide the electrical path between the integrated circuit and the external package interface.

Applications

The West Bond wirebond-R1 is used for electrical contact formation between semiconductor dies and packages. The tool supports wedge bonding for standard access and deep access bonding geometries.[2]

The West Bond wirebond-R1 is suited to wirebonding with gold or aluminum wire in integrated circuit packaging workflows. The tool is intended for room temperature thermosonic bonding with those wire materials and sizes.[2]
