The invention provides a multi-layer PCB stacking method. The multi-layer PCB stacking method comprises the steps of: receiving a stacking instruction, and performing PCB stacking according to the stacking instruction; obtaining a bonding pad identifier, and performing bonding pad choking on a corresponding PCB according to the bonding pad identifier, so that a bonding pad PCB is obtained; obtaining a copper sheet identifier, and performing copper sheet choking on a corresponding PCB according to the copper sheet identifier, so that a copper sheet PCB is obtained; respectively performing choking detection on the bonding pad PCB and the copper sheet PCB, and, when the fact that the choking detection of the bonding pad PCB or the copper sheet PCB is unqualified is judged, performing prompt marking on the corresponding PCB; placing a heat transfer plate between adjacent PCBs, and pressing the stacked PCBs; and, obtaining coding information, and performing coding marking on the PCBs according to the coding information. According to the multi-layer PCB stacking method provided by the invention, the PCBs are subjected to bonding pad choking or copper sheet choking; therefore, various laminates are conveniently distinguished; the processing error due to wrong distinguishing is prevented; the quality of multiple PCBs is improved; and low production efficiency due to difficult distinguishing is prevented.
Description
technical field [0001] The invention relates to the technical field of PCB boards, in particular to a multilayer PCB board stacking method. Background technique [0002] In recent years, with the recovery of the semiconductor industry, the circuit board market has continued to develop, which is mainly due to two driving forces. First, the market space for the circuit board application industry continues to expand, and the application of the communication industry and the notebook computer industry has improved, making the high-end multilayer circuit board market grow very rapidly. At the same time, the proportion of digital circuit boards used in color TVs, mobile phones, and automotive electronics has also increased significantly, which has continuously expanded the space for the circuit board industry. Due to the fierce competition in the PCB industry, some major PCB manufacturers actively develop new technologies, increase the number of PCB layers or promote the marketiz...
