Abstract

The invention discloses a PCB production method in the technical field of production methods. The method comprises the following steps: 1, carrying out material confirmation, wherein a material is selected, a professional engineer carries out detailed carding on requirements after the final requirements provided by a customer are received, and a product PPT is manufactured, and is provided for thecustomer for reexamination; and 2, printing a drawn circuit board with transfer paper, selecting a manufacturing circuit board with the best printing effect, manufacturing the circuit board with a photosensitive plate in a whole-course diagram, coating copper films on two sides of the circuit board, and cutting a copper-clad plate into the size of the circuit board. According to the PCB production method, in the drilling link after material confirmation, the bottom plate can be preset, the safety of the PCB machining process is guaranteed, corrosive liquid is prepared, pre-machining is conducted, then fine sandpaper polishing is conducted in a matched mode, the line processing precision after corrosion is improved, the production method is more reasonable, the production effect of the PCBis improved, and the probability of defective products is reduced.

Description

technical field

[0001] The invention discloses a method for producing a PCB board, and specifically belongs to the technical field of production methods. Background technique

[0002] PCB board, also known as printed circuit board, is a provider of electrical connections for electronic components. Its design is mainly layout design; the main advantage of using circuit boards is to greatly reduce wiring and assembly errors, improve automation level and production labor rate, According to the number of layers of circuit boards, it can be divided into single-sided boards, double-sided boards, four-layer boards, six-layer boards and other multi-layer circuit boards.

[0003] The single-sided board is on the most basic PCB, the parts are concentrated on one side, and the wires are concentrated on the other side. The double-sided board has wiring on both sides, but to use the wires on both sides, there must be a proper circuit connection between the two sides. The multilayer boar...
