A double-sided circuit board

Abstract

This utility model discloses a double-sided circuit board, including a circuit board body. Several components are fixedly mounted on the top and bottom ends of the circuit board body, and several heat dissipation assemblies are also mounted on the top and bottom ends of the circuit board body. A double-sided threaded tube is threaded through and connected to the rear end of the circuit board body. This double-sided circuit board, by incorporating heat dissipation assemblies, allows the processing center to be connected to the heat-generating components (such as components and resistors) via internal circuitry within the circuit board body. Several heat sinks absorb and dissipate heat, preventing overheating and further extending the lifespan of the electronic components within the circuit board body. The double-sided threaded tube allows for adjustment of the distance between the top and bottom surfaces of the circuit board body and the inner wall of the fixed circuit board before installation, reducing the possibility of contact between the electronic components and the inner wall of the fixed circuit board, and preventing damage from compression.

Description

Technical Field

[0001] This utility model relates to the field of circuit boards, and more particularly to a double-sided circuit board. Background Technology

[0002] A double-sided circuit board (PCB) is a printed circuit board with conductive copper layers on both sides. Through-holes (or vias) connect the circuitry between the two sides, allowing for more complex circuit layouts within a limited space without significantly increasing the board's size. This design greatly improves the integration and functional density of the circuit board. PCBs have evolved from single-layer to double-layer designs; double-sided wiring allows designers greater flexibility in circuit layout, meeting the miniaturization and high-performance requirements of electronic products.

[0003] Traditional double-sided circuit boards, due to the dense distribution of components, can cause some load-bearing components to overheat. This heat cannot dissipate effectively, leading to component damage or even short circuits. Traditional double-sided circuit boards are often directly fixed inside a fixed plate, and the different sizes of the components on both sides can cause electronic components on one side of the circuit board to come into direct contact with the inner wall of the fixed plate, easily resulting in damage from compression. Traditional double-sided circuit boards lack waterproof components, and accidental contact with water can cause short circuits. Utility Model Content
