Disclosed is a printed circuit board manufacturing process including extruding nuts. The manufacturing process comprises the following steps: preparing, according to the shapes and features of the extruding nuts (20), an auxiliary jig (10) for placing the extruding nuts (20), with several nut placement holes (13) in cooperation with the extruding nuts (20) being provided on the auxiliary jig (10); placing the extruding nuts (20) in the nut placement holes (13) on the auxiliary jig (10); carrying out pre-fixation of a PCB (40) and the extruding nuts (20); after the pre-fixation is completed, using a laminating device for the conventional production of the PCB (40) to embed the extruding nuts (20) into the PCB (40), and riveting installation of the extruding nuts (20) being completed; and finally, carrying out processing and treatment for the shape of the PCB (40). The printed circuit board (40) manufacturing process including the extruding nuts (20) has the advantages of a high riveting efficiency, a high precision and a good flatness, allows a jig to be utilized again, and dispenses with a special riveting apparatus for the extruding nuts (20).
Description
technical field [0001] The invention relates to the technical field of manufacturing printed circuit boards, in particular to a manufacturing process for printed circuit boards containing extruded nuts. Background technique [0002] Extruded nuts, also known as self-clamping nuts, are a kind of nuts applied to thin plates or sheet metals. One end has embossed teeth and guide grooves. A nut head with a round shape. When in use, the teeth of the extruded nut can be extruded into the plate by pressure, causing plastic deformation around the hole, and the deformed objects are extruded into the guide groove, thereby producing a locking effect. [0003] This method of manufacturing a PCB with extruded nuts is usually to complete the finished PCB first, and then install the extruded nuts. The current installation method of extruded nuts usually requires a special nut riveting machine to install the nuts individually. In actual use, these nut riveting machines are not dedicated t...
