Abstract

Boron-doped diamond films are deposited on cobalt cemented tungsten carbide (WC-Co) printed circuit board (PCB) milling tools using hot filament chemical vapor deposition (HFCVD) method. Trimethyl borate is used as boron source. Scanning electron microscope (SEM) and Raman spectroscopy are used to characterize the as-deposited diamond films. To evaluate the cutting performances of as-fabricated boron-doped diamond (BDD) coated milling tools, milling tests are conducted using copper-clad laminate(CCL)as the workpiece material, compared with microcrystalline diamond (MCD) coated and uncoated milling tools. The experimental results show that the BDD films have strong adhesive strength to the substrate and can protect the cutting edge from rapid wearing out. The results suggest that depositing BDD coating on WC-Co milling tools is a viable way to improve their cutting performances in machining of PCB materials.
