Manufacturing method of rigid-flexible plate

Abstract

The invention relates to a manufacturing method of a rigid-flexible plate, mainly comprising the following steps: firstly, a plurality of flexible plate areas are manufactured on a flexible plate basematerial, and adjacent positions of each flexible plate area of the flexible plate base material are provided with holes for respectively forming a rigid plate operating area; then, rigid plate pressing operation is carried out on the flexible plate base material, and rigid plate areas are respectively formed in the rigid plate operating areas; finally, necessary electrical connection is completed between the flexible plate areas and the flexible plate areas, and the rigid-flexible plate is formed after cutting. With the technique, the preparation of pressing operation can be completed on thesame flexible plate base material through a single plate overlapping step so as to complete the manufacture of the rigid-flexible plate, thereby the invention can enhance the manufacture process efficiency and the product qualification.

Description

technical field [0001] The invention relates to a method for manufacturing a rigid-flex board, in particular to a method for manufacturing a rigid-flex board with irregular shapes without the need for multiple positioning and alignment steps. Background technique [0002] All electronic products are highly interested in reducing the size, and one of the means of reducing the size is to use the limited space for maximum efficiency. Therefore, the important component inside the electronic product: "circuit board" must also be in form. Meet the requirements of effective use of space. As for how to reduce the space occupied by the circuit board, folding or rolling is the direction that can be considered, but the premise is that the circuit board must be flexible. With the current technology, flexible circuit boards (or thin film circuit boards) can meet this requirement, but they cannot completely replace rigid circuit boards in terms of structure and function, so the so-called...

Problems solved by technology

However, the above-mentioned manufacturing process is not obvious when it is used to manufacture regular and fixed-shaped rigid-flex boards. However, when it is used to manufacture irregular-shaped rigid-flex boards as shown in Figure 7, the manufacturing process becomes cumbersome and complicated: The soft and hard board 60 (not shown in the figure) shown in Figure 7 has six soft board parts 61-66 of different shapes, and a hard board part 67 of different shapes is set between adjacent soft board parts 61-66. In this situation, the following problems will arise:

[0011]2. When the flexible board modules cut out from the aforementioned different flexible board substrates are used in the rigid board manufacturing process, different flexible board modules must use fixtures separately Perform a positioning alignment, thus increasing the probability of errors during alignment

[0012]3. The small-area flexible board module involves precise space arrangement, which is a very difficult challenge for the design and use of fixtures

[0013] It can be seen that the above-mentioned existing hard and soft board manufacturing process obviously still has inconvenience and defects in the manufacturing method and use, and needs to be further improved urgently

In order to solve the problems existing in the manufacturing process of soft and hard boards, relevant manufacturers have tried their best to find solutions, but no suitable design has been developed for a long time, and there is no suitable method for general manufacturing methods to solve the above problems , this is obviously a problem that relevant industry players are eager to solve
