Huilian Electronics, a leading enterprise in the PCB micro-cutting tool industry, specializes in the R&D and manufacturing of PCB end mills with diameters ranging from 0.1 mm to 0.5 mm. Its customers include global top-100 PCB manufacturers such as Foxconn and AT&S. With surging demand for high-precision products—including IC substrates and chip packaging substrates—the limitations of conventional coated micro-diameter tools have become increasingly evident: frequent tool breakage, rapid edge wear, poor coating adhesion, and non-uniform coating coverage on small-diameter sections—resulting in substandard machining accuracy for fine grooves, persistently high tool-breakage rates, and delays in fulfilling high-end precision orders. There is an urgent need to overcome technical bottlenecks in micro-diameter tool coating technologies.
Targeting the core challenges of precision machining with micro-diameter tools, this solution employs nanocrystalline CVD diamond coating technology. Coating thickness is precisely controlled to maximize retention of cutting-edge sharpness; deposition process parameters are optimized to ensure uniform, full-coverage coating over the entire micro-diameter cutting edge, significantly enhancing coating chipping resistance and adhesion. Tailored specifically for IC substrate and high-precision PCB machining conditions, the coating features low friction and superior wear resistance. In addition, comprehensive services—including one-on-one technical support, rapid sample iteration, and full-chain quality control for batch coating—are provided to meet the stringent requirements of high-precision, minimal-stock-removal machining.
Tool breakage rates for micro-diameter end mills decreased by 85%; tool service life increased 22-fold; machining accuracy for fine grooves and isolation slots fully meets the stringent tolerance requirements of IC substrates. The product successfully passed mass-production validation with multiple high-end customers, reinforcing Huilian Electronics’ global market leadership in PCB micro-diameter cutting tools. Revenue contribution from high-end cutting tools rose by 30%, successfully breaking the foreign technological monopoly on coated cutting tools.
