[0002] Printed circuit board, also known as printed circuit board, printed circuit board, often uses the English abbreviation PCB, is an important electronic component and the support of electronic components. Because it is made by electronic printing technology, it is called a "printed" circuit board. Before the emergence of printed circuit boards, the interconnection between electronic components was directly connected by wires to form a complete circuit. PCBA is the abbreviation of Printed Circuit Board Assembly in English, that is, the entire process of PCB blank board after SMT mounting or DIP plug-in, referred to as PCBA. This is a commonly used writing method in China, while the standard writing method in Europe and the United States is PCB'A, with "'" added, which is called the official idiom. For example, CN210609874U disclosed on the Chinese patent website is a PCBA main control board for portable satellite communication equipment that combines Ethernet service forwarding, WIFI data transmission and reception, GPS positioning, equipment status monitoring and management, output reference clock and other functions and devices into one PCBA board, effectively reducing the shortcomings of multiple modules, large volume and low integration of portable equipment, and reducing product costs. The utility model does not consider the installation and disassembly of the PCBA main control board, so a PCBA main control board that is easy to disassemble and maintain is proposed to solve the problems mentioned in the above background.
