Lanrui v9 fault detector

 Works and Key Features

The Lanrui V9 fault detection agent facilitates fault diagnosis, especially for short circuits and overheating components, by making the thermal behavior of the board visible. 

• Application Method: The agent is typically applied as a spray over the suspected area of the circuit board.
• Detection Principle: It works by applying a layer of frost to the board. When power is applied, the faulty area (e.g., a short circuit or an overheating component) melts the frost faster than the surrounding areas, clearly indicating the problem spot.
• Residue-Free: A key feature highlighted by merchants is that the formula is residue-free, which helps maintain the integrity of sensitive electronic components and avoids contamination or damage.
• Non-Flammable: The spray is described as non-flammable, making it a safer option for use in electronics repair environments compared to some other chemical agents.
• Applications: It is widely used by professionals for diagnosing issues in mobile phone motherboards, laptops, and other electronic devices, helping to identify intermittently faulty capacitors, resistors, semiconductors, and poor solder joints.
