AI Technical Summary

Technical Problem

Existing chip testing equipment is prone to glare when testing small-sized BIOS chips, making it difficult to provide sufficient light, resulting in unclear images and low testing efficiency. Furthermore, the equipment is too bulky to be installed on existing production lines.

Method used

It employs a cylindrical light source assembly and a ring-shaped visual inspection device. The light source assembly is open in the vertical direction, while the visual inspection device moves in the horizontal direction. It combines an edge computing platform for real-time inspection, uses an arched curved surface light source and a ring guide rail in conjunction with oblique angle shooting, and combines a convolutional neural network model for real-time defect identification.

Benefits of technology

It achieves high-precision and high-efficiency chip defect detection, avoids reflection problems, expands the shooting range, simplifies the equipment structure, facilitates installation on existing production lines, and improves detection efficiency and accuracy.

Abstract

This utility model discloses a chip inspection device, relating to the field of chip inspection technology. The chip inspection device includes a mounting base, a light source assembly, and a vision inspection device. The mounting base has a support area. The light source assembly is mounted on the mounting base and located above the support area. The light source assembly is cylindrical, defining an illumination space that is open both vertically and horizontally. The lower end of the illumination space covers the support area. The vision inspection device is horizontally mounted to the mounting base and located above the support area, at the upper end of the illumination space. The vision inspection device is used to acquire image information of the chip to be inspected located within the support area. The light source assembly forms a cylindrical illumination space. By covering the chip to be inspected at the lower end of the illumination space, the surface and surrounding parts of the chip can be illuminated. The movable arrangement of the vision inspection device expands the imaging range. The overall structure is simple and easy to install into existing server motherboard assembly lines.
