What it is
The West Bond 4KE Series is a semi-automatic wire bonder for microelectronics packaging.[1]
The West Bond 4KE Series belongs to West Bond’s semi-automatic bonder line and is positioned alongside equipment for wire bonding, die attach, and related microelectronics packaging tasks.[1]
How it works
General reference — not yet source-verifiedA semi-automatic wire bonder places and bonds fine interconnect wire between bond targets on a package or device.
A wire bonder of this class uses controlled motion in multiple axes to form repeatable bond loops and to reach bond sites across the work area.
Where it fits in the process flow
General reference — not yet source-verifiedThe West Bond 4KE Series is used in microelectronics packaging after the device or package has reached a stage where fine wire interconnects must be added.
A semi-automatic wire bonder fits between package preparation and final assembly or test, where wire connections must be placed with controlled geometry and repeatability.
Applications
The West Bond 4KE Series is suited to high power and high frequency device bonding.[1]
The West Bond 4KE Series is used for semiconductor, microwave, RF, and hybrid production.[1]
