Abstract

The invention provides a de-burring method for a high-frequency printed circuit board. The method comprises the following steps of providing a multi-layer ceramic base printed circuit board with a slot; according to the size of the slot, providing a first milling knife, wherein a computer digital control system controls the first milling knife through a mechanical milling machine to crudely mill the slot; according to the size of the slot, providing a second milling knife, wherein the computer digital control system controls the second milling knife through the mechanical milling machine to finely mill the slot. Compared with the prior art, the de-burring method for the high-frequency printed circuit board provided by the invention has the advantages that the high-frequency board is molded in the mode that crude milling in the positive direction and fine milling in the negative direction are combined, i.e. the milling knife with the width smaller than the width of the slot is used for cutting the middle of the slot in the position where the slot is required to be molded to crudely mill, and then the milling knife with the width equal to the width of the slot is used for fine milling in the reversing direction, so that burrs generated when the knife is positively travelled are removed, and the aim of de-burring the surface of the high-frequency printed circuit board is fulfilled.

Description

technical field [0001] The invention relates to the field of manufacturing printed circuit boards, in particular to a method for deburring high-frequency printed circuit boards. Background technique [0002] As a special basic carrier in the electronic communication industry, high-frequency printed circuit board plays a very important role in the communication industry. Its main characteristics are high signal frequency, low transmission speed, and low signal loss. At present, among ceramic-based printed circuit boards, aluminum oxide substrate (AIO) printed circuit boards are the most widely used due to their high cost performance. Ceramic-based printed circuit boards, especially multi-layer ceramic-based printed circuit boards, are high-end products in printed circuit boards because of their high technical content, difficult production, and wide application range. Ceramic-based printed circuit boards are mainly aimed at high-density power supply products and high-frequenc...
