Motherboard fault detector cooling liquid Lanrui V9 450ml

🔍 Professional Fault Detector for Motherboards and Electronic Circuits

🔧 Locate faults on motherboards and other printed circuit boards (PCBs) quickly and effectively with the Lanrui V9 Freezing Spray. This powerful, ultra-fast evaporating coolant is an indispensable diagnostic tool for electronics technicians.

📷 The Lanrui V9 instantly lowers the temperature of the component or area it is sprayed on, creating a localized "thermal shock" effect. This allows you to:

🔍 Identify Short Circuits and Overheated Components: On a powered board (with due caution!), by spraying a light frost on the surface, the component that is shorted or drawing excessive current will heat up rapidly, causing the frost or coolant in that specific spot to evaporate before it does elsewhere. This will make it immediately visible.

🔧 Detect Intermittent Faults: Some electronic components (such as capacitors, resistors, transistors or ICs) can only malfunction when they reach a certain temperature. By selectively cooling them with the Lanrui V9, you can temporarily restore them to normal operation, thus isolating the faulty component.

✅ Shake the can well before use.

✅ To identify overheating/short circuits (on a powered board, be careful!): Spray short blasts to create a thin film of frost on the suspected area. Observe carefully: the spot that defrosts first indicates the component that generates the most heat.

✅ For intermittent faults: With the device turned on and malfunctioning, selectively spray the suspected components. If the fault temporarily disappears after cooling a component, that is likely the culprit.

✅ Wait for the product to evaporate completely before re-powering the board, if it was turned off during the test.
