Technical Specifications

Key Product Attributes

1. Material Excellence

The use of Tungsten Steel ensures that the blade maintains its structural integrity even under high-speed rotation. Unlike standard stainless steel, tungsten steel offers:

• Extreme Heat Resistance: Maintains sharpness even when friction generates high temperatures.

• Anti-Corrosion: Resists oxidation from flux residues and cleaning chemicals.

• Rigidity: Minimal flexing during precision work, reducing the risk of "skipping" across a delicate circuit board.

2. Precision Engineering

With a 0.4mm tip, this tool is specialized for "surgical" accuracy on motherboards.

• IC Chip Cleaning: Effortlessly removes "underfill" glue or black resin around CPU and NAND chips without damaging the underlying copper pads.

• Trace Repair: Ideal for scratching away solder mask to reveal broken traces for jumper wire installation.
