2D/3D Visual Optical Inspection System for Quad Chip

Visual inspection scheme for use in optical solder joint inspection system

An optical solder joint inspection system(0SIIS) has been developed for the automatic visual inspection of soldered parts on the printed circuit boards. Its advantages over existing techniques include the detection of 3-0 shape of specular objects with high reliable and high speed. In this paper, we will propose a solder joint inspection scheme for a prototype of the OUIS. The inspection scheme...

Stent optical inspection system calibration and performance.

Implantable medical devices, such as stents, have to be inspected 100% so no defective ones are implanted into a human body. In this paper, a novel optical stent inspection system is presented. By the combination of a high numerical aperture microscope, a triple illumination system, a rotational stage, and a CMOS camera, unrolled sections of the outer and inner surfaces of the stent are obtaine...

New DUV Optical Wafer Inspection System

OVERVIEW: In the midst of the rapid acceleration in the advancement of technology nodes, there is a demand for improved performance of waferinspection systems, namely, greater sensitivity as device size moves toward higher integration and density, newer materials such as ArF resist, Cu wiring and low-k films, and higher throughput with 300-mm-diameter wafers. In response to these demands, Hitac...

Automated optical inspection system for analogical resistance type touch panel

The touch panel is the most important and promising technical product nowadays. Automated optical inspection (AOI) technology provides objective measurement, shorter production period and better production quality. The purpose of this paper is to develop an automated optical inspection system for analogical resistance type touch panel. This system integrates mechanism, electrical control and ma...
