7400D - Conventional 45° Wire Feed Wedge Bonder
7600D - Deep Access 90° Wire or Ribbon Feed Wedge Bonder

CONVENTIONAL 45 degree wire feed and unique clamp design of West·Bond’s Model 7476E Series wedge-wedge wire bonders provide the precision and control for the smallest, most accurate loop formations. Consistent and repeatable profiles are easily achieved with the patented single lever X-Y-Z micromanipulator and optical Z encoder.

CONVERTIBILITY for a variety of bonding methods is pioneered by West·Bond. A simple exchange of wire clamp assemblies, provided with specified models, allows conventional 45º wire feed, deep access 90º wires or ribbon feed, and single point tab/lead bonding. All programmed bond variables and machine settings for each tool head are retained in memory and retrieved automatically upon conversion.

PROGRAMMING for three different device types may be entered into separate buffers. Each device wire may have up to 21 stitch bonds with individual ultrasonic power, time, force (high or low) and loop elevation control data. Program values, action prompts, and fault diagnostics are exhibited on the easy to read 4 line, 40 character LCD sequentially with machine operation.

FEATURES include programmable dual force (high or low), bond tool positioning utility, pneumatic braking of Z and Y axes during bonding, and radiant tool heat. Available with or without adjustable height platform.
