Abstract
A machine vision based scanner system for an offline binning handler including a line scan camera capable of scanning a full tray-width image of a media tray, a camera controller operatively connected to the line scan camera, a tray transport mechanism positioned below the line scan camera, a tray transport mechanism controller operatively connected to the tray transport mechanism and the camera controller and processing software for using the images captured by the line scan camera to identify and sort a plurality of devices.
Claims14
A machine vision based scanner system for scanning semiconductor devices having an identification mark in an offline binning handler comprising:
- a line scan camera capable of scanning a media tray holding the semiconductor devices and capturing a full tray-width image of the media tray;
- a camera controller operatively connected to the line scan camera;
- a tray transport mechanism positioned below the line scan camera;
- a tray transport mechanism controller operatively connected to the tray transport mechanism and the camera controller;
- and
- an image processor configured to execute image processing software for using the image captured by the line scan camera to identify and sort the semiconductor devices held in the media tray.
