Locate short circuits and overheating components on phone motherboards and PCBs fast with the JTX IR-3 Motherboard Short Circuit Finder Pad. This professional thermochromic silicone detection pad is a smart, affordable alternative to expensive thermal cameras and messy rosin tests.

Simply place the flexible 0.5 mm pad over the powered board. When a component overheats due to a short circuit (temperature ≥35°C), the pad instantly changes color from its original hue to white at the exact hotspot — giving you a clear visual indicator of the fault location. Once cooled below 35°C, the color returns to normal, making the pad fully reusable.
