Technical Field
[0001] This utility model relates to the field of circuit board technology, and specifically to a circuit board that is easy to assemble and disassemble. Background Technology
[0002] A circuit board, also known as a printed circuit board, is a crucial component of the electronics industry, serving as the carrier for the electrical interconnection of electronic components. Almost every electronic device, from small items like electronic watches and calculators to large systems like computers, communication equipment, and military weaponry, requires a circuit board to enable the electrical interconnection between integrated circuits and other electronic components.
[0003] Most existing circuit boards require screws to secure them at their four corners during use. However, this installation method requires tools to disassemble and reassemble the circuit board during subsequent maintenance. Without tools, disassembly and reassembly are impossible, leading to inconvenience in disassembling and reassembling the circuit board. After repeated disassembly and reassembly, the screw holes will wear down, resulting in unstable installation. Utility Model Content
