Test fixture of image sensor chip and with test light source

Abstract

The invention discloses a test fixture of an image sensor chip and with a test light source. The test fixture comprises the test light source and the test fixture. The test light source is fixed at the upper end of the test fixture. According to the test fixture of the image sensor chip and with the test light source, the test light source is arranged on the test fixture directly, the push and pull action of the traditional LED (Light Emitting Diode) surface light source is not required, and accordingly the operation time is saved and the working efficiency of workers is improved; a single LED lamp bead serves as a light emitting source and is combined with a light uniform plate and accordingly the light source is stable, the service life is long, the light is uniform, and the like, and accordingly the loss of the test yield of the image sensor chip due to light source problems is greatly reduced; compared with the traditional LED surface light source, the brightness of the light source can be accurately adjusted due to a potentiometer and accordingly the brightness of the light source can be easy to change, the use personnel can perform adjustment conveniently, and the requirements for different light source brightness values of different products can be met.

Description

technical field [0001] The invention belongs to the field of single image sensor chip testing, and in particular relates to an improved structure of a test light source and a test fixture for sensor chip testing. Background technique [0002] In today's situation of image sensor chips being in full swing, in large and small image sensor chip manufacturing enterprises, the chip test light source used must meet two basic conditions: uniformity of light and long service life. [0003] The semiconductor industry is a fully competitive industry. Products with high performance and low price, that is, high cost performance, are the trump card for enterprises to win in the brutal market competition. Cost reduction is a problem that all companies are considering, and how to bring high profits with low cost is the pursuit of enterprises. The pursuit of cost performance is reflected in everything, and the same is true for the requirements for LED light sources and test fixtures for se...

AI Technical Summary

Problems solved by technology

The traditional test light source is an LED surface light source (using multiple arrays of LED lamp beads), and its design has disadvantages such as large heat dissipation, high energy consumption and high cost; and the traditional LED surface light source needs to manually push the test fixture into the LED during the test process. Under the LED light-emitting board of the surface light source, not only the operation is cumbersome, the efficiency is low, but also it is easy to wear; moreover, the brightness adjustment of the traditional LED surface light source is not accurate enough
