Description

Technical Field

[0001] The present application relates to the field of printed circuit boards, and in particular to a modular printed circuit board. Background Art

[0002] Printed circuit board, also known as printed circuit board, printed circuit board, is an important electronic component, a support for electronic components, and a provider of circuit connections for electronic components. Because it is made using 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. The circuit panel only existed as an effective experimental tool, and the printed circuit board has become an absolute dominant position in the electronics industry. In the early 20th century, in order to simplify the production of electronic machines, reduce the wiring between electronic parts, and reduce production costs, conventional circuit boards were used. After the substrate was installed stably, electronic components were installed on the surface of the substrate with the help of solder joints, and several docking grooves were opened at one end of the substrate to facilitate data transmission with the equipment.

[0003] With respect to the above-mentioned related technologies, the inventors believe that conventional circuit boards are mostly integral substrates, which leads to partial short circuit or damage at the upper end of the circuit board. Since the small size of the circuit components requires welding workers to have more sophisticated welding skills, most circuit boards are repaired by directly replacing the entire circuit board, resulting in a waste of resources.

[0004] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field.
