CVD diamond-coated drill bits, characterized by exceptional hardness, wear resistance, low friction, and high thermal stability, deliver extended service life, high precision, high efficiency, reduced defect rates, and cost-effective performance enhancement in PCB manufacturing—making them the preferred drilling solution for premium PCBs, high-frequency boards, HDI boards, and high-layer-count multilayer boards.
Doubled Lifespan: Standard FR-4 boards achieve a drill bit lifespan 3–5 times longer than conventional tungsten carbide bits; for high-hardness substrates (e.g., M9, high-Tg materials), lifespan increases by 5–20 times—significantly reducing tool changes and machine downtime.
Exceptional Precision: Hole positional deviation ≤ ±25 μm; hole diameter tolerance ≤ ±0.003 mm; hole walls are burr-free and delamination-free—ideal for HDI microvias and high-layer-count PCBs.
Outstanding Efficiency: Compatible with high-speed spindles (80,000–180,000 RPM); feed rates increase by 20–30%; breakage rate is low; yield improves by 5–15%.
Controllable Costs: Cost per hole decreases by 30–50%; reduces drill bit procurement and machine setup costs; equipment utilization increases by over 20%.
Broad Application Compatibility: Perfectly suited for advanced PCB manufacturing—including high-layer-count boards, high-frequency/high-speed boards, HDI microvias, heavy-copper/substrates, and ceramic-based substrates.
