PCB circuit board structure and manufacturing process thereof

Abstract

The invention discloses a PCB circuit board structure and a manufacturing process thereof. The PCB circuit board structure and the manufacturing process of the PCB circuit board structure comprise a board body, fixing holes are formed in the periphery of the upper surface of the board body, mounting holes are formed in the upper surface of the board body, a waterproof sleeve is arranged on the outer side of the board body, second fixing grooves are formed in the periphery of the board body, a first clamping block is arranged on the inner side surface of the waterproof sleeve, cooling strips are additionally arranged at the bottom of the board body, the cooling strips are installed in installation grooves, and when the circuit board works, a large amount of heat is generated, the heat on the board body is transferred to the cooling strips, the heat is dispersed through the cooling strips, the temperature of the board body is reduced, and the damage of electronic components on the boardbody is avoided, on the other hand, the waterproof sleeves are additionally arranged on the periphery of the board body, the waterproof sleeves are respectively fixed in the second fixing grooves andthe first fixing grooves through the first clamping blocks and the second clamping blocks, so that the damp condition of the board body can be effectively prevented.

Description

technical field [0001] The invention belongs to the technical field, and in particular relates to a PCB circuit board structure and a manufacturing process thereof. Background technique [0002] PCB circuit board, also known as printed circuit board, is the provider of electrical connection for electronic components. Its development has a history of more than 100 years, and its design is mainly layout design; the main advantage of using circuit boards is that it greatly reduces wiring and assembly errors, and improves the 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. Since the printed circuit board is not a general terminal product, the definition of the name is slightly confusing. They are not the same, so when evaluating the industry, the two are related but cannot be said to be the s...
