MaAnt MR-003 Thermal Silicone Pad – PCB Hotspot Locator
MaAnt MR-003 Thermal Indicator Silicone Pad – PCB Hotspot Locator
The MaAnt MR-003 Thermal Indicator Silicone Pad is a smart, color-changing diagnostic sheet designed for mobile phone and PCB motherboard troubleshooting. Simply lay it over a powered board and watch it instantly reveal overheating fault zones — no calibration, no complex software, and no expensive thermal imaging device required. Made in Mainland China.
How It Works
The silicone sheet is engineered with a thermochromic layer that triggers at 35°C. When a component or trace on the motherboard reaches or exceeds that threshold, a visible white spot appears directly over the problem area, giving you a precise, at-a-glance map of short-circuit locations and abnormal current leakage points. Once the board cools below 35°C, the pad returns to its transparent state — ready to use again.
Key Features
- 35°C Color-Change Trigger: White spots appear instantly at overheating fault points, helping you pinpoint short circuits and leakage positions with speed and confidence.
- High Transparency: Crystal-clear silicone lets you directly observe motherboard routing and identify faulty components without removing the pad.
- Flexible & Soft Construction: Bendable, wear-resistant, and anti-corrosion material conforms closely to the mainboard surface for accurate thermal detection.
- Reversible & Reusable: The pad restores its original clear color once cooled, making it a cost-effective, long-lasting addition to your repair toolkit.
- Zero Calibration Needed: Place it on the powered board and start reading — faster and far more affordable than a dedicated thermal imager.
- Safe & Eco-Friendly: Smoke-free operation, leaves no residue, and will not harm sensitive PCB components during troubleshooting sessions.

Frequently Asked Questions
Q: At what temperature does the MaAnt MR-003 silicone pad change color?
A: The MaAnt MR-003 thermal indicator pad activates at 35°C. Any area on the PCB or motherboard that reaches or exceeds this temperature will cause a white spot to appear on the pad directly above it, clearly marking the hotspot or short-circuit location.
Q: Can the MaAnt MR-003 silicone pad be reused after each diagnostic test?
A: Yes — the pad is fully reusable. Once the motherboard cools below 35°C, the white indicators fade and the pad returns to its transparent state, ready for the next repair session without any loss of performance.
Q: Is the MaAnt MR-003 pad safe to use on sensitive PCB components?
A: Absolutely. The silicone pad produces no smoke, leaves zero residue, and is made from anti-corrosion, eco-friendly silicone material. It is safe to place directly on powered motherboards and precision PCB components without causing any damage.
Q: Does the MaAnt MR-003 replace a thermal imaging camera for phone repairs?
A: It serves as a highly affordable and practical alternative for most everyday repair scenarios. While a dedicated thermal imager provides a full digital heat map, the MR-003 quickly highlights the same hotspot locations at a fraction of the cost — making it ideal for phone repair shops and electronics technicians on a budget.
