The West Bond 4KE is a semi-automatic wire bonder known for its 3-way convertible design, allowing it to be used for wedge, ball, or ribbon bonding. It features a gantry design with a motorized Z (vertical) and Y (forward/backward) axis for programmed wire loops, and a manually controlled X (side-to-side) axis. This system is ideal for high-power and high-frequency applications requiring precise, repeatable bond shapes and is popular in the microwave, semiconductor, and hybrid product industries.

Key Features and Capabilities

3-Way Convertible Design:
Quickly switch between wedge, ball, and ribbon bonding by exchanging the bond head, clamp assembly, and software mode.
Motorized Z and Y Axes:
Microprocessor-controlled motors drive the Z and Y axes for precise, programmed control over the wire loop height and shape, maintaining consistency for multiple bonds.
Manual X Axis:
A unique West•Bond micromanipulator allows for manual, precise positioning of the target location.
Gantry Design:
The entire mechanism is positioned above the workplane, allowing for unlimited part size and shape accommodation for both small and large components.
Dual Force Mechanism:
Provides two pre-set force values, allowing for either a high or low force to be programmed for any bond.
Radiant Tool Heat:
The bond tool is heated with a panel-mounted radiant heater controlled by a constant current.
Integrated Vision System:
A high-resolution camera with a crosshair generator provides an accurate view of the bonding area, allowing for precise target acquisition on an external monitor.
ESD Protection:
The system includes conductive and dissipative features to protect against electrostatic discharge.

Applications

High-Frequency and High-Power Devices:
Excellent for applications where identical bond and loop shapes are critical, such as in microwave, semiconductor, and hybrid products.
Large Substrates:
The gantry design and throat-less chassis provide unlimited access to remote bonding targets on large packages and modules.

Bond Force: 10 – 150 grams;

Au / Al wire: Wedge 0.7 to 3 mil, Ribbon: 0.5x2mil to 1x10 mil, Au Ball Bonding: 0.7 to 2 mil.
