TOOLS IR-3 Motherboard Short Circuit Finder Pad Flexible Heat for Mobile Phone Repair Accurately Locate Hotspots Instantly

Product Overview

JTX TOOLS IR-3 – Motherboard Short-Circuit Finder Pad
Thermochromic Silicone | Reusable | High-Transparency Fault Detection Pad

The JTX TOOLS IR-3 is an innovative, reusable silicone pad designed to quickly and accurately locate short-circuit heat sources on all types of motherboards. By utilizing advanced thermochromic technology, this pad changes color at temperatures ≥35°C, instantly revealing hotspots with clear white marks. It offers a smarter, healthier, and more cost-effective alternative to traditional rosin methods and expensive thermal imagers.

Key Features & Benefits

1. Instant Heat Color Alert

• The pad changes color when the temperature rises above 35°C.

• White spots appearing on the pad precisely indicate the location of hot short-circuit points.

• Enables intuitive, visual fault inspection without complex equipment.

2. High Transparency & Clear View

• Designed with exceptional transparency, allowing you to see the motherboard components clearly through the sheet.

• Accurately locate faulty components and trace mainboard circuits with ease.

3. Flexible & Conformable (0.5mm Thin Silicone)

• Soft, bendable silicone sheet at just 0.5mm thickness.

• Fits closely over components, ensuring enhanced contact and accurate heat transfer for reliable detection.

4. Reusable & Multi-Cycle Usable

• Once heated, the color resets when cooled below 35°C, ready for repeated use.

• Lower consumable costs compared to disposable methods.

5. Healthier & Cleaner than Rosin

• Traditional rosin detection uses a 120°C melting point, producing hard-to-clean residues that may damage parts and cause further short circuits.

• The IR-3 is smokeless, odorless, and leaves a tidy workbench—no harmful fumes, no sticky cleanup.

6. More Hassle-Free than Thermal Imaging

• No focusing, calibration, or complicated setup required.

• Simply attach the pad to the motherboard and power on for testing—white dots instantly reveal hotspots.

• Thermal imagers are costly, require focus and calibration, and involve time-consuming operations.

3 Easy Steps for Detection

1. Attach the IR-3 pad to the surface of the motherboard.

2. Power On the board for test operation.

3. Observe – white dots will clearly mark the short-circuit hotspots.

Comparison vs. Traditional Methods

VS. Rosin Detection:

• Rosin melts at 120°C, releases smoke, leaves residues, and may damage components.

• IR-3 works at lower temperature (≥35°C), smokeless, odorless, and leaves no residue.

VS. Thermal Imager:

• Thermal imagers are expensive, require focusing and calibration, and have a steep learning curve.

• IR-3 is high cost-performance, requires no setup, and is ready to use in seconds.

Function & Application

• Primary Function: Locate short-circuit heat sources on various mainboards (PC, laptop, gaming console, industrial boards, etc.).

• White Mark = Hot / Short-Circuit Point – intuitive fault inspection.

• Suitable for repair technicians, engineers, hobbyists, and educational use.

Why Choose JTX TOOLS IR-3?

• Cost-Effective – Lower total cost than thermal imagers or repeated rosin use.

• Time-Saving – No calibration, no warm-up, instant visual results.

• Safe & Eco-Friendly – No toxic fumes, safe for prolonged use.

• Durable & Reusable – Built for multiple repair cycles.

• Precise & Reliable – Accurately pinpoints the exact short-circuit spot.
