Abstract
A Printed Circuit Board (PCB) diagnosis system based on infrared thermal imaging is described in this paper. Multi-scale edge detection and nonlinear regression methods are used for heat source recognition and thermal feature extraction respectively. Thermal pattern recognition is implemented by support vector classifier instead of traditional Back-Propagation Feed-Forward Network (BPFFN) classifier, which generates poorly on the diagnosis application, and good experimental result has been achieved.
