Soft and hard combined plate structure capable of avoiding fracture of soft plate

Abstract

The invention discloses a soft and hard combined plate structure and aims at providing the soft and hard combined plate structure, which can avoid the fracture of a soft plate when pressing the soft plate and hard plates. The soft and hard combined plate structure comprises the soft plate (1) arranged on the inner side and the hard plates (2) arranged on the front side and the back side of the soft plate (1), and the joint heights of the hard plates (2) on the front side and the back side of the soft plate (1) with the soft plate (1) are different. The difference between the joint heights of the hard plates (2) on the front side and the back side of the soft plate (1) is set to be not less than 0.5mm. The soft and hard combined plate structure can be widely applied in the field of design of soft and hard combined plates in electronic equipment.

Description

technical field [0001] The invention relates to a structure for preventing soft and hard boards from breaking. Background technique [0002] Rigid-flex boards take into account the double-sided installation of hard boards, better rigidity, and thickness that meets structural requirements, and also take into account the advantages of flexible boards that can be bent arbitrarily. Rigid-flex boards are more and more widely used in electronic equipment. At present, the structure of flexible and rigid boards adopts the structural form of the inner layer of the soft board and the outer layer of the hard board. During production, the soft board in the inner layer is usually prepared first, and then pressed together with the hard board. In the area without the hard board, the hard board needs to be punched off first, or the pattern is punched out and removed in the subsequent process. Excess hardboard. Such as figure 1 As shown, under normal circumstances, since the cross-sectio...

AI Technical Summary

Problems solved by technology

like figure 1 As shown, under normal circumstances, since the cross-sections of the upper and lower hard boards 3 are flush, the soft board 4 at the transition between the soft and hard boards is easily squeezed under strong pressure during the production process. , there is a great stress

This kind of extrusion may appear as a disconnection of the flexible board, or the flexible board has no bad performance in a short period of time, but in the subsequent assembly of the whole machine, or even a disconnection during the consumer's use, resulting in machine failure Happening
