PCB ASSEMBLY GUIDE PIN OF BOARD TEST FIXTURE USING INFRARED CAMERA, ESPECIALLY FOR SUGGESTING REFERENCE POINTS FOR EXACTLY MATCHING IMAGE PHOTOGRAPHED BY THE CAMERA WITH CAD DATA

摘要

PURPOSE: A PCB(Printed Circuit Board) assembly guide pin of a board test fixture using IR(InfraRed) cameras is provided to accurately detect defect portions and defect elements of a test PCB assembly by suggesting reference points for matching an image photographed by the camera with CAD(Computer Aid Design) data. CONSTITUTION: A PCB assembly guide pin of a board test fixture using IR cameras includes a support member(100) and a heat emitter(200). The support member is made of a material having low heat conductivity and includes a lower portion fixed on a fixture board and an upper portion inserted into a guide pin hole of the PCB assembly. The heat emitter is inserted to an upper portion of the support member and generates heat using supplied power.
