WYLIE WL-756L PCB Fault Locator Pad – 35°C Heat Detection Sheet
WYLIE WL-756L PCB Fault Locator Pad – 35°C Heat Detection Sheet
WYLIE WL-756L Reusable PCB Fault Locator Pad – 35°C Heat Detection Sheet
Diagnose and pinpoint short circuits on phone motherboards faster and more accurately with the WYLIE WL-756L Fault Locator Pad. This innovative, reusable silicone heat-detection sheet changes color at 35°C, instantly revealing hot spots on any PCB — so you can zero in on the exact fault location without guesswork, probes, or lengthy diagnostic sessions.
Whether you're a professional mobile repair technician or a seasoned electronics hobbyist, this thermal detection sheet is an essential addition to your toolkit. Simply place the sheet over the motherboard, apply a low-voltage current, and watch as the thermochromic layer highlights the precise area generating excess heat — identifying the short circuit component in seconds.
Key Features

Frequently Asked Questions
Q: What does the WYLIE WL-756L heat detection sheet do?
A: The WYLIE WL-756L is a reusable thermochromic silicone pad designed for PCB short circuit testing. It changes color at 35°C to visually highlight the exact location on a phone motherboard or circuit board that is generating excess heat, helping technicians quickly locate fault points without invasive probing.
Q: Is the WL-756L detection sheet reusable?
A: Yes! The WL-756L is made from durable silicone with a thermochromic layer that is designed for repeated use. Once it cools down after each test, the color reverts and it is ready to be used again on your next PCB diagnosis.
Q: What types of circuit boards is it compatible with?
A: The WYLIE WL-756L heat detection sheet is compatible with most compact circuit boards including smartphone motherboards, tablet PCBs, and other small consumer electronics boards where short circuit detection is needed.
Q: Does using this sheet damage the motherboard?
A: No. This is a non-destructive diagnostic tool. Simply lay it over the board, apply a safe test voltage, observe the heat pattern, then remove it. No soldering, cutting, or component removal is required during the detection process.
