Copper clad plate cutting method

Abstract

The invention relates to the field of circuit boards, and particularly discloses a copper clad plate cutting method. In the cutting method, a cutting device is adopted, the cutting device can conductgrinding treatment on the four cut corners of a copper clad plate at the same time in the using process, and the grinding efficiency of the corners of the copper clad plate is improved; and meanwhile,ground copper clad plates are stacked on a receiving plate and can be centralizedly collected conveniently, and the stacked copper clad plates do not need to be arranged again. Through the scheme, the grinding efficiency of the corners of the copper clad plate can be improved.

Description

technical field [0001] The invention belongs to the field of circuit boards, and in particular relates to a cutting method for copper clad boards. Background technique [0002] The Chinese name of PCB is printed circuit board, also known as printed circuit board. It is an important electronic component, a support for electronic components, and a carrier for electrical connections of electronic components. The processing process of the formed printed circuit board is complicated, including cutting, drilling, copper sinking, pattern transfer, pattern electroplating, stripping, etching, green oil, characters, gold-plated fingers, forming, testing and final inspection. Processing steps, each step also includes several small processing steps, such as the cutting step, the specific processing is to cut the copper clad laminate, the cutting step can make the size of the copper clad laminate and the processed printing The size of the circuit board is suitable, and then the cut copp...

Problems solved by technology

[0004] When the materials in the bonding sheet are metal plates and glass fiber cloth, after the copper clad laminate is cut, there are generally metal debris or glass fiber cloth debris left after cutting, metal debris or glass fiber cloth debris on the section of the copper clad laminate. Fiber cloth debris is easy to adhere to the corners of the copper clad laminate, and metal debris or glass fiber cloth debris is easy to scratch the surface of the copper clad laminate during the process of moving the copper clad laminate, resulting in poor color quality of the entire copper clad laminate; There are excess medium metal and glass fiber cloth at the corners of the cut copper clad laminate, so it is necessary to use a chamfering device to grind the multiple corners of the copper clad laminate separately, resulting in low grinding efficiency and reduced copper clad laminate. Processing efficiency; at the same time, it will cause metal debris or glass fiber cloth debris to be generated again on the copper clad laminate, and further cleaning of the metal debris or glass fiber cloth debris will be required, which will complicate the cutting and processing of the entire copper clad laminate, and increase the The probability of the surface of the copper clad laminate being scratched
