BACK-LIGHT BLOCK FOR SEMICONDUCTOR VISION SYSTEM

摘要

A backlight block of a vision system for a semiconductor device can align a semiconductor package at an exact position without disturbing a photographing for vision inspection of the semiconductor package. The backlight block includes: a seating block for seating a semiconductor package to be subject to a vision inspection; and an alignment means movably located on the seating block in such a manner that the alignment means can be moved toward or away from the semiconductor package so as to align the semiconductor package.
