Research on the Related Problems of PCB Standard Thermal Image Establishment
摘要
Abstract
The first task of fault diagnosis is to establish the PCB standard thermal image.This paper studies the processing method of sample thermal image in the process of establishing the standard thermal image,and proposes to use the principal compo-nent analysis method instead of the weighted average method,the effect is better.The calculation methods of completely reasonable cooling time and ideal power-on time during adjacent power-on of a single sample circuit board are studied,which provides a basis for the study of PCB standard infrared images in the future.关键词
