1. High Thermal Conductivity: The aluminum material effectively dissipates heat, reducing drill bit temperatures and minimizing the risk of resin buildup in the chip grooves.
2. Superior Flatness and Surface Hardness: These properties ensure drilling precision, reduce drill deflection, and prevent drill breakage, enabling a smooth and reliable manufacturing process.
3. Burr Reduction: With high surface hardness and material rigidity, burr formation is significantly minimized, resulting in improved hole wall quality.
4. Circuit Board Protection: The aluminum drilling entry sheets safeguard circuit boards by preventing scratches and pressure marks, ensuring the integrity of the PCB surface.
