Problems solved by technology

[0003] However, this installation mode first needs to open a through hole on the circuit board, which will affect the wiring layout of the circuit board itself, and will also affect the line stability of the traces around the through hole
Second, such vias will affect the mechanical strength of the board itself
More importantly, this installation mode will cause an imbalance in the mechanical force on the circuit board itself during the fastening process, resulting in the breakage of the circuits in each layer of the circuit board.

Abstract

A convenient-detachment and quick-heat-radiating circuit board assembly comprises a circuit board device (3) and a base fixing device. The circuit board device (3) comprises a rectangular body part (30) and four fixing legs (31) which are arranged at corners of the rectangular body part. The base fixing device comprises a base (1) and four mounting frames (4) which are fixed on the base (1) and correspond with the four fixing legs (31). Each mounting frame (4) is internally provided with an insertion trough (40) for insertion of the fixing leg (31). The mounting frame (4) is provided with an inside clamping block (8) which is pressed by a pressing spring (83) and can extend into the insertion trough (4) at the inside part of the insertion trough (40), wherein the inside part of the insertion trough is next to the inside of the body part (30) of the circuit board device (3).

Description

technical field [0001] The invention relates to the field of circuit boards, in particular to a circuit board assembly that is easy to assemble and disassemble and can dissipate heat quickly. Background technique [0002] The installation and removal of the circuit board will affect the operation stability and reliability of the equipment using the circuit board, and will affect its maintainability. The installation of the current circuit board often adopts the method of opening a hole on the circuit board and inserting the circuit board through the fixing column arranged on the equipment rack. Holds the circuit board in place and can be removed for maintenance during use. [0003] However, this installation mode first needs to open a through hole on the circuit board, which will affect the wiring layout of the circuit board itself, and will also affect the stability of the wiring around the through hole. Second, such vias affect the mechanical strength of the board itself...
