Description

This West-bond 7400A Manual Ultrasonic/Thermosonic 45° Feed Wedge-Wedge Wire Bonder (s/n 6966) looks to be in good cosmetic condition, showing some signs of wear. 


We have a technician who refurbishes these machines for us, so we are selling it in working condition. Please allow 2 to 4 weeks for him to go thru the machine to make sure it is performing up to factory specs. 


It comes with everything shown, including an Ultrasonic Generator, a B&L SZ4 StereoZoom 4 Microscope (0.7X to 3.0X) with eyepieces, and a Heated Workholder with Temperature Controller, as shown (the microscope, generator and workholder/controller shown in the photos above are not necessarily the exact ones you will receive; they are shown merely to represent what a complete system will look like). 


Consumables (wire and wedges) are not included. A list of vendors can be provided.


We recommend having the bonder crated for shipment, the cost of which will be the responsibility of the buyer. 

Approximate overall unpacked dimensions: 24"L x 21"W x 14"H.


"The Westbond model 7400A is an ultrasonic/thermosonic wedge-wedge wire bonder designed to interconnect wire leads to semi-conductor, hybrid or microwave devices. The machine bonds aluminum or gold wires ranging from 0.0007 in. to 0.002 in. Bonds are made by the wedge-wedge technique using ultrasonic energy to attach aluminum wire at room temperature and adding work piece heat for gold wire. Wire is clamped and threaded diagonally under the bonding wedge, allowing independent feeding action but requiring front-to-back bonding direction. The bonding tool is lifted and lowered manually by the operator usind hand/eye reference to the work elevations and to loop height."
