Model 4750 Die Ejector System

Overview

The Model 4750 Die Ejector System, also known as the Poker Plate, will help speed up die handling through these key features:

  • Adaptable to most die handling & die bonding systems
  • Virtually maintenance free
  • One moving part
  • Stand alone die plating system

Description

High Speed Die Handling
The Model 4750 Poker Plate System solves the problem of quick and easy die removal from wafer mounting tape. It can be supplied as a stand alone unit or can be interfaced into your regular or high speed die bonding, pick and place or die inspection equipment. 

In operation as a stand alone unit, the operator aligns the desired die over the poker pin and presses the foot petal. The vacuum locks the carrier in position and the poker lifts the die from the wafer mounting tape for easy removal with a vacuum pencil. In operation, in conjunction with your pick and place or die bonder, the operator aligns the desired die to the cross hair in the microscope or viewscreen, the vacuum locks the carrier in position and the poker lifts the die from the wafer mounting tape for pickup by your die bonding arm. The operator continues to align the cross hair to the next die. 

The Model 4750 is adaptable to almost all die carrier ring or die carrier plate systems in use today or Semiconductor Equipment Corporation can supply ring sets compatible with your system. When interfaced with SEC´s Model 830, the Model 4750 will present die to the pickup tool compatible rates.


Only One Moving Part-Virtually Maintenance Free
The system is unique in that unlike competitive systems which utilize cams etc. which frequently malfunction and need adjustment, there is only one moving part in the Model 4750 and the only energy source required is vacuum. Therefore downtime and maintenance are virtually zero.
