Problems solved by technology

Existing technology and equipment can only produce conventional products with a plate thickness below 3.2mm, but cannot produce products with a thickness exceeding the above or metal substrates
There is a patented method of using a 150V-CUT knife to increase the speed of processing, but the 150 V-CUT knife is a tungsten steel product, and the tooth density material is soft. It can only produce conventional FR4 PCB products with a thickness of less than 3.2mm, and its life is short.
For PCB products with high hardness or metal materials, 150 tungsten steel V-CUT cutters are used to produce the cutters, and the tool life will be shortened by more than 90%. For ultra-thick metal-based products with a thickness of 3.2-5.0mm, the V-CUT machine can not be processed

Abstract

The invention provides a method for processing a V-type groove of an ultra-thick metal substrate printed board, and the method comprises the following steps of S1, election of a V-CUT machine and a V-CUT knife; S2, design of V-CUT processing data; S3, setting of V-CUT processing parameters; and S4, inspection of the processing dimension of the V-type groove of ultra-thick metal substrate products.The invention starts from the technical capability of the equipment and the material technical capability of the tool, and designs V-CUT processing of the special ultra-thick metal-based printing circuit board through the technical capability of the V-CUT machine equipment and the deeper technical development of the V-CUT knife material and angle, thereby ensuring that ultra-thick and high-hardness metal substrate microwave products can be produced in batches, quickly and safely, improving product quality, and solving the technical problem that conventional V-CUT machines and V-CUT knives cannot produce ultra-thick metal substrates.

Description

technical field [0001] The invention belongs to the technical field of PCB processing, and in particular relates to a processing method for a V-shaped groove of an ultra-thick metal substrate printed board. Background technique [0002] Metal-based printed boards replace FR4 and brittle ceramic substrates in the field of high-frequency microwave communication composed of long-distance communication, navigation, medical treatment, transportation, transportation, storage power modules, intelligent optoelectronics, and digital systems, with good heat dissipation performance and more stable dimensions, so that The problem of thermal expansion and cold contraction of different materials of components on the printed board is alleviated, and the durability and reliability of the whole machine and electronic equipment are improved. However, the thickness of the metal base is between 1.0-3.2mm, and the thickness of some PCB boards is between 3.2-5.0mm. For products with process edg...
