Flexible board reinforcing and laminating method

Abstract

The invention discloses a flexible board reinforcing and laminating method. The method comprises the following steps of: S1, processing an integral reinforcing sheet, processing a reinforcing board into the size matched with the size of a flexible board splicing board to form a reinforcing whole board and integrally milling a reinforcing sheet matched with the flexible board splicing board on thereinforcing whole board, S2, conducting riveting: riveting and fixing the reinforcing sheet and the flexible board splicing board after the reinforcing sheet and the flexible board splicing board arealigned and matched to form a flexible board with a semi-fixed structure, and S3, carrying out quick pressing and enabling the above well-riveted and fixed flexible board of the semi-fixed structure to be laminated with the reinforcing sheet. The flexible board reinforcing and laminating method provided by the invention is suitable for various reinforcing boards, especially FR-4 reinforcing boards, the reinforcing board is firstly milled to have the same size as the flexible board splicing board, then the size and the shape of fitting of the reinforcing sheet corresponding to the flexible board are milled on the whole board, and all the reinforcing sheets are connected through stamp holes to form integral reinforcement; and then the board edge alignment holes are used for alignment, and the reinforcing sheet and the flexible board body are fixed in a riveting mode, so that the integral fitting of the flexible board reinforcing sheet is realized.

Description

technical field [0001] The invention belongs to the technical field of flexible board reinforcement, in particular to a method for reinforcing and laminating flexible boards. Background technique [0002] For flexible boards connected by multiple rigid modules, multiple reinforcements need to be laminated during fabrication. In order to ensure the support of the flexible board during processing and subsequent soldering of components, it is generally necessary to design a reinforcement area inside the flexible board, and to design a reinforcement area outside the flexible board. At present, the reinforcement is generally done manually. The general steps are: first punch (or mill) the reinforcement sheet to be laminated, [0003] Then, on the flexible board to be reinforced, use screen printing to screen out alignment lines for the alignment of the reinforcement, and then manually paste the formed reinforcement sheet on the corresponding position. If the bonding reinforcemen...

AI Technical Summary

Problems solved by technology

[0004] The existing technology has the following disadvantages: Since the design requires reinforcement both inside and outside the flexible board, there are the following disadvantages: 1. The efficiency of manual reinforcement is low and the labor cost is high; 2. Manual reinforcement The accuracy is low, and it is easy to cause problems such as skewing and poor fit; 3. Since both the inside and the outside need to be reinforced, there are complicated and repeated problems in operation; 4. Especially for FR-4 reinforcement Material, because the FR-4 reinforcement material is relatively hard, if there is a small space for lamination, it is more likely to have problems such as misalignment and slippage; 5. The efficiency of whole board subsidy is low and the effect is poor
