Model 4546E - Two-Way Convertibility, 45° Wire Feed, or 90° Wire and Ribbon Feed
at a fraction of the cost. Microprocessor controlled motor drives for both Y and Z axes bond a succession of parallel, single or multiple arched wires maintaining identical loop and bond shapes. Unlimited deep-reach access to bond targets on IC packages of any X-Y dimension with West·Bond’s throatless chassis and micromanipulator designs. Ideal for bonding high power, high frequency devices where identical bond and loop shapes are critical.
for angled and vertical wire feed wedge bonding is easily accomplished with a simple change of clamping mechanisms, both of which are included with Model 4546E. All program variables and bond settings for each configuration are retained in memory between conversions.
for different types of wire connections are entered into separate buffers, each with individual ultrasonic power, time, force (high or low) and loop control data. Each type may have up to 100 bonds, and may be repeated for any number of wires for up to a maximum of 6,000 individual bonds. Program values, action prompts and fault diagnostics are exhibited on the easy to read 4 line, 40 charater LCD sequentially with machine operation.
include 63 kHz ultrasonics, orthogonal X-Y-Z axes with pure vertical Z, color video and microscope targeting, motion slaved Z encoder, pneumatic braking of X-Y-Z axes during bonding, and built-in tool heat. Available with the base and work platform for tabletop applications, or without base and work platform for mounting above any work handling system.
