Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of PCB board processing, in particular to a PCB board alignment device. Background Art
[0002] PCB, also known as printed circuit board, is one of the important components of electronic devices. Circuits are formed on it and through holes are provided to achieve electrical connections between various electronic components.
[0003] When manufacturing PCBs, copper foil, prepreg, copper-clad substrates, and other materials need to be cut to specifications, stacked, and pressed together, and then tightly bonded using high temperature and high pressure, a process known as lamination. Before lamination, the materials need to be aligned. Conventional methods employ alignment holes, which involves setting alignment holes at the same fixed position on each layer, inserting multiple PINs into the alignment holes of the bottom layer, and then stacking the other materials in sequence according to the layer structure of the PCB. Each layer of material has its alignment holes inserted through corresponding PINs, and finally, steel plates are used to press and isolate the aligned groups of materials until the lamination process is complete. However, in the prior art alignment methods, each layer of the structure needs to have its alignment holes individually aligned with PINs, resulting in low alignment efficiency. Therefore, a PCB alignment device is needed to address this issue. Utility Model Content
