1. What is PCB CTI Value? Comparative Tracking Index (CTI) is a vital electrical property of PCB materials that measures their resistance to tracking—a phenomenon where carbonized, conductive paths form across an insulating surface due to electrical stress and moisture. The higher the CTI value, the better the insulation performance under harsh conditions such as high voltage and humidity. A high...
