00181_TSHOO_9 11/6/00 5:17 PM Page 5-7 5-3 PCB Inspection 5-3-1 Cautions for Part Replacement 1. The human body carries much static electricity. Before touching a part for repair, replacement or the similar purpose, be sure to touch a grounded metallic portion by hand to let the static electricity go through the metallic portion to the earth. Especially when handling any micro computer or IC, carefully remove such static electricity before touching them. 2.
