4526 Manual Wedge Bonder


Note: This model is no longer manufactured and is only available now as a refurbished system.

The 4526 manual wedge bonder by MPP (formerly K&S Manual Wire Bonders Division) is now obsolete and available only as a used/refurbished model. Please contact us for further information, available stock or servicing requirements.

The system is extremely simple to set-up and for ease of use incorporates analog controls, which allow rapid adjustment of individual bonding parameters.

The system is capable of ultrasonically bonding a wide range of gold / aluminium wires and ribbons from 12 - 75 micron wire through 25 x 250micron ribbon. A motorised Y axis with auto-stepback provides controlled wire length and repeatable loop formation. In addition, the system has a large working area and table motion, with excellent Z axis clearance, for bonding small through large devices.

The 4526 advantages include:

  • Incorporates proven quality, components and reliability
  • Excellent bond quality to a wide variety of materials
  • One bond head supports deep access and standard bonding
  • Excellent results in tight geometries and looping
  • Programmable auto stepback distance from 1st to 2nd bond
  • Large bonding area 134x134mm
  • Motorized wire clamp ensures precise control
  • Bonds aluminium wire: 20-76 microns (0.8-3 mil) diameter.
  • Bonds gold wire: 12-76 microns (0.5-3 mil) diameter.
  • Au or Al ribbon bonding capability to 25x250microns.
  • Excellent tail length control with 30° or 45° wire feed angle
  • Real time fine adjustment of movements on the front panel
  • Extremely simple to learn and operate
  • Large installed user base and spare parts availability
