They connect various electronic components through circuits and are key electronic interconnects of electronic products. Circuit boards are divided into single-sided boards, double-sided boards and multi-layer circuit boards according to the number of layers. Smartphones and tablets are important application areas in the electronic circuit board market. With the coverage of 5G networks, the requirements for electronic circuit boards will also be higher.

[0003] The application range of electronic circuit boards is relatively wide, so there are many types of electronic circuit boards, including spliced ​​electronic circuit boards, etc.

[0004] However, the connection structure strength between the two circuit boards of the existing spliced ​​electronic circuit board is relatively weak, and the two circuit boards are prone to breakage during use, thereby causing losses.

[0005] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content
