The West Bond 353637 E 90 is a wire bonder. The West Bond 353637 E 90 has a bonding area of 5.375" × 9.5". The West Bond 353637 E 90 uses 2400B Series software.[1][2]
Wire bonders make electrical connections by attaching fine wire between device bond pads and package or substrate connection points. Wire bonders are used after device fabrication and singulation or substrate preparation, when an assembled part needs interconnection to complete the electrical path. Wire bonding can be carried out with different bonding methods depending on the bond head, wire material, and package geometry.
Packaging and bonding tools sit in the assembly portion of semiconductor manufacturing rather than in front-end wafer patterning. Wire bonders are used after a die or device has been placed into a package, onto a substrate, or onto another carrier that exposes connection points for interconnect. Wire bonding is followed by later assembly operations such as encapsulation, lid attach, inspection, and electrical test, depending on the product flow.
The West Bond 353637E-90 is intended to bond groups of parallel wires on work pieces pre-aligned for front-to-back bonding. The West Bond 353637E-90 accepts aluminum wire in wedge-wedge bonding, and the same method also accepts gold wire with work piece heat. The West Bond 353637E-90 can be converted from angled-clamp wire feed to vertical-feed wedge bonding for deep-walled work packages.[3]
