Riveting and positioning fixture, PCB riveting method, manufacturing method for PCB and PCB

Abstract

The invention provides a riveting and positioning fixture. The riveting and positioning fixture comprises a fixture body; two opposite sides of the fixture body are respectively provided with a plurality of rivet installation holes; one of the other two opposite sides of the fixture body is provided with a first positioning slide groove extending along a Y-axis direction, and the other of the other two opposite sides of the fixture body is provided with a second positioning slide groove extending along an X-axis direction; and a pin can slide in the first positioning slide groove and the second positioning slide groove and can be fixed at a designated position. The invention also provides a PCB riveting method, a manufacturing method for a PCB and the PCB. According to PCB riveting technology provided by the invention, riveting requirements of all standard jointed board products can be met only by manufacturing one riveting and positioning fixture, so production management is simplified; a pulling force generated in the riveting process can be effectively reduced, thereby avoiding scraping caused by dislocation and improving product yield; after pressing, rivets are drilled out through drilling, so the problems of board separation and delamination at positions where the rivets are located in later processing are overcome.

Description

technical field [0001] The invention relates to the field of PCB (Printed Circuit Board) manufacturing, more specifically, to a riveting positioning fixture, a PCB riveting method, a method for manufacturing a PCB, and a PCB. Background technique [0002] In the process of manufacturing PCB, the alignment accuracy between layers determines the ability of the platen. When the thickness of the core board is greater than 0.5mm and the matching structure is greater than 3 prepregs, the melt glue process cannot effectively fix the layers. At this time, the riveting process is required for production. [0003] However, the traditional riveting process is affected by the riveting method and the stress problem during the riveting process, which often leads to problems such as misalignment and loose riveting, which eventually lead to the scrapping of the board due to misalignment. At the same time, the traditional positioning fixtures are made separately according to each model, whi...

Problems solved by technology

[0003] However, the traditional riveting process is affected by the riveting method and the stress problem during the riveting process, which often leads to problems such as misalignment and loose riveting, which eventually lead to the scrapping of the board due to misalignment.

At the same time, the traditional positioning fixtures are made separately according to each model, the production management is chaotic and the production efficiency is low

[0004] In the traditional prepreg riveting process, when multiple high-resin-content prepregs are pressed together with a large-thickness core board, the pulling force due to the fluidity of the resin is very large, and it is prone to misalignment and scrapped

Traditional riveting design will not meet product requirements
