Dual-Head Leadframe Wedge Wire Bonder (Heavy Wire)


Product Description

The Bondjet BJ931, Fully Automatic Dual-Head Leadframe Wedge Bonder is an ultrasonic wedge bonder developed especially for maxtrix leadframe applications. The application of two bondheads enables two different wire sizes as well as a combination of wire and ribbon to be bonded simultaneously. The fully automatic dual-head leadframe wedge bonder Bondjet BJ931 meets the latest technology and flexibility demands for automotive and power electronics applications; handling heavy aluminium, copper wire and ribbon on two specialized bondheads that can be exchanged. A robust, clean design, low maintenance requirements, user-friendly software and service support functions are integrated into the Bondjet BJ931, along with Hesse Mechatronics’ industry-leading PiQC™ process monitoring system.
