How It Works
The pen acts as a rosin atomizer. When you place small pieces of solid pine rosin inside its heating chamber and power it on, it vaporizes the rosin into a thick white smoke. You then coat the target motherboard (such as an iPhone, MacBook, or smartwatch PCB) with this dense white layer of rosin flux residue.
Once the board is coated, you apply power to the motherboard. The shorted or faulty component will quickly overheat, instantly melting the white coating over it and turning clear or jet black. This visually isolates the exact point of failure within seconds.
Key Features
- Upgraded Bulb Atomizer: Designed with a larger chamber to hold and vaporize rosin evenly.
- No Soldering Iron Required: Replaces the old, cumbersome method of using a hot soldering iron tip to melt rosin onto a board.
- USB Rechargeable: Features a built-in battery charged via a standard USB port, making it fully portable.
- Overcharge Protection: The integrated smart charging head features a protection chip to extend battery life.
- Ergonomic Design: Shaped like a thick marker or pen for precision handling over microscopic components.
Step-by-Step Usage
- Load the Rosin: Drop a small piece of solid rosin flux directly into the glass atomizer heating chamber.
- Preheat: Press and hold the power button to activate the internal heating element.
- Coat the Board: Direct the nozzle over the target area of the PCB to deposit an even layer of white rosin frost.
- Detect the Fault: Connect a DC power supply to the motherboard. Watch for the exact spot where the white coating instantly melts away to reveal the shorted component.
