The invention discloses a novel riveting machine platform. The novel riveting machine platform comprises a platform body, a plurality of first positioning holes are uniformly arranged in one side of the platform body, the opposite sides of the first positioning holes are provided with positioning grooves, and positioning bases are arranged in the positioning grooves, can slide in the positioning grooves and are provided with second positioning holes. The technical problem that an existing riveting machine platform in the prior art is inaccurate in positioning is solved, and alignment accuracy of a core plate and a prepreg is greatly improved. In addition, the second positioning bases can slide in the positioning grooves, requirements of different sizes of core plates are met, trouble to manufacture different riveting machine platforms for different types of printed circuit boards is avoided, production cost of printed circuit boards is reduced, and application range of the riveting machine platform is enlarged.
Description
technical field [0001] The invention belongs to the field of mechanical processing, and in particular relates to a printed circuit board riveting table and a printed circuit board manufacturing method using the same. Background technique [0002] Multilayer printed circuit board refers to a circuit board made of hard and soft printed circuit boards alternately put together and pressed together. The positioning method between layers of multilayer printed circuit boards in the process of lamination can be divided into pins Positioning lamination process (PIN-LAN) and pinless positioning lamination process (MASS-LAM), the former has high positioning accuracy, but low efficiency and high cost, and is only suitable for the production of high-layer, high-precision multilayer printed circuit boards , the latter has high efficiency and low cost, and is currently the production method adopted by most manufacturers. [0003] The process flow of pinless positioning lamination is as fo...
