Description

Technical Field

[0001] This utility model relates to the field of circuit board technology, and more specifically, to a circuit board for electronic devices with high shock and impact resistance. Background Technology

[0002] Circuit boards are named as follows: ceramic circuit board, alumina ceramic circuit board, aluminum nitride ceramic circuit board, circuit board, PCB board, aluminum substrate, high frequency board, thick copper board, impedance board, PCB, ultra-thin circuit board, ultra-thin circuit board, printed circuit board, etc. Circuit boards miniaturize and visualize circuits, playing an important role in the mass production of fixed circuits and the optimization of electrical appliance layout. Plug-in circuit boards are also a type of circuit board; when a fault occurs, only the corresponding board needs to be replaced, without requiring overall repair.

[0003] However, existing electronic circuit boards do not have any impact-resistant structure, which means that when the circuit board is hit by external parts or objects during use, the electronic components on the surface of the circuit board are easily damaged.

[0004] Furthermore, most traditional plug-in circuit boards are installed using a snap-fit ​​method. This type of installation structure has poor shock resistance, which can cause the circuit board to become loose and thus affect the normal use of electronic devices. Utility Model Content
