Description

Technical Field

[0001] The utility model relates to the technical field of PCB boards, and in particular to a research and development device for a high-stability aluminum sheet mesh plug-hole PCB board. Background Art

[0002] With the rapid development of electronic products, the printed circuit boards (PCBs), which serve as the carriers of these products, have also experienced rapid growth. This rapid development has also put forward new requirements for PCB production and structure, such as high-density circuits and lightweight structures. To meet these requirements, blind via PCBs, buried via PCBs, and multi-stage buried blind via PCBs have emerged. The emergence of these PCBs has strictly improved production process requirements and production technology. Currently, solder masking is a key processing step in the PCB manufacturing process, and plugging is a common method for soldering through-holes (also known as vias) on PCBs. Existing high-stability aluminum mesh plugged via PCBs require PCB board fixing during development and production. However, the existing technology for fixing PCB boards is too simple, making it difficult for workers to adjust the fixing force. If the fixing is too tight, it may damage the internal circuitry of the PCB board, thus affecting subsequent use. Utility Model Content
