Abstract

The cost of printed circuit boards with multi-layered voltage planes has created the need for an easy to use tool that can detect, locate, verify and analyze hidden defects causing shorts. The use of a Thermal Image Analyzer (TIA) in conjunction with a hipot test and high voltage stress give manufacturing such a tool. This tool, controlled by a personal computer, directs the operator in the correct analysis procedures needed to safely detect, with thermal image analysis, the defective area of the product. The tool is capable of applying a high-voltage test and low- current stress to leakage defects. The tester can then apply constant power to the defect using low voltage (less than 24 VDC), enabling detection with the TIA. The entire operation is transparent to the manufacturing operator who when trained in the use of the TIA, can detect, isolate, categorize and repair internal and/or surface defects related to multi-layered printed circuit boards. This paper deals with the infrared detection and repair of defects in printed circuit boards as a manufacturing process.
