Abstract

The invention discloses a miniature PVD coat miller cutter for PCB, and a making method thereof. The miniature PVD coat miller cutter for PCB comprises a substrate and one or more layers of a hard and wear-resistant coat deposited on the substrate through a physical vapor deposition process; the hard and wear-resistant coat is an MeCxNyOz coat, Me is one or more of Al, Cr, Ti, Zr, Si, Hf, Nb, Ni, W, Ta, B, V, Y and Cu, and x+y+z is 1; and the total thickness of the one or more layers of the coat on the substrate is 0.1-10mum. The substrate is made by using a cemented carbide material, a ceramet material, a ceramic material, a cubic boron nitride based material or a high-speed steel material. By improving the structure of the PVD coat in the invention, a processing problem that printed circuit boards are difficult to process is overcome, and a problem that the service life of a common miniature milling cutter is short is prolonged.

Description

Technical field [0001] The invention relates to the field of micro milling cutters for printed circuit boards and their coatings, in particular to a PVD composite coating micro milling cutters mainly used for printed circuit boards and a preparation method thereof. Background technique [0002] PCB (Printed Circuit Board) for short is a circuit product made with printing or image transfer technology. In all kinds of products in modern society, from computers and TVs to mobile phones and IC cards, as long as there are circuits in the products, there are printed circuit boards. With the implementation of the European Union RoHS (the directive restricting the use of certain hazardous substances in electrical and electronic equipment), the environmentally friendly PCB version has undergone tremendous changes under the RoHS requirements. The global PCB industry has entered the era of lead-free compatibility and halogen-free environmental protection. However, in order to ensure dimens...
