A kind of manufacturing process of anti-oxidation pcb printed circuit board

Abstract

The invention discloses a production process of an anti-oxidation PCB (Printed Circuit Board). The production process comprises the operation steps of raw material mixing, board face printing, surfacedrying and finished product detection. A user simultaneously pours green oil and a UV curing material into a mixing barrel, a vapor phase inhibitor is added, and mixing equipment is started up to enable a stirring rod in the mixing barrel to rotate at a high speed so as to sufficiently mix the green oil and the UV curing material and uniformly dope the vapor phase inhibitor in the green oil and the UV curing material; and a circuit board is sunk by a copper deposition automatic line, the circuit board is immersed into sulfuric acid, thick copper is added, a layer of thin copper is deposited on the surface of the circuit board, the copper-clad circuit board is fixed on printing equipment, an A surface of the circuit board is printed by the printing equipment, and after the circuit board isoverturned, a B surface is printed. According to the production process of the anti-oxidation PCB, which is disclosed by the invention, oxidation resistance of the circuit board can be effectively improved, yield in the printing process of the PCB is promoted, and equipment has an overturning part taking structure so as to facilitate operation of a user.

Description

technical field [0001] The invention belongs to the technical field of circuit board printing, and in particular relates to a production process of a circuit board, in particular to a production process of an anti-oxidation PCB printed circuit board. Background technique [0002] The printed circuit board is the PCB circuit board, also known as the printed circuit board. It is the provider of the electrical connection of electronic components. Its design is mainly layout design. The automation level and production labor rate can be divided into single-sided boards, double-sided boards, four-layer boards, six-layer boards and other multi-layer boards according to the number of layers of circuit boards. Since printed circuit boards are not general terminal products, the definition of the name Slightly confusing, it is not equivalent to a printed circuit board. The printed circuit board we usually refer to is a bare board, that is, a circuit board without components; [0003] ...

AI Technical Summary

Problems solved by technology

[0003] The existing PCB printing circuit board manufacturing process has certain disadvantages in the operation process. The traditional PCB circuit board printing process uses traditional ink mixed with UV curing materials as raw materials, so that the surface of the PCB printed circuit board is easily damaged after a long period of use. Oxidation occurs, which reduces the service life of PCB printed circuit boards. Traditional PCB printed circuit boards need to manually touch the printed PCB circuit boards in the board printing environment, and dry the circuit boards. During the contact process , The ink on the PCB printed circuit board will cause certain harm to the user. The traditional PCB printed circuit board is in a fixed state during the drying process, so that the surface of the PCB printed circuit board cannot be heated evenly, which increases the drying time of the PCB printed circuit board. time required, and traditional PCB circuit boards are prone to misprints due to external forces during the printing process, which will bring certain adverse effects to users
