Embodiment Construction

[0054] In order to make the purpose, features and advantages of the present invention more obvious and understandable, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the following The described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0055] In order to solve the problem that the existing rigid-flex board is prone to tearing during bending and use due to the limited design value of the width of the flexible region 11, an embodiment of the present invention provides a rigid-flex board that can utilize The soft-hard joint area 12 expands the soft area 11 to increase the be...

Abstract

The invention relates to the technical field of PCBs, and discloses a rigid-flex board and a manufacturing method thereof. The rigid-flex board comprises a flexible board, a first bonding sheet and a first rigid board which are laminated in sequence, wherein the flexible board comprises a flexible area and a rigid-flex combination area; the flexible area comprises an original flexible area and an extended flexible area; the rigid-flex combination area comprises first combination areas and second combination areas, the first combination areas are connected to the two sides of the flexible area in the width direction, and the second combination areas are located on the two sides of the extended flexible area in the length direction, separated from the extended flexible area and connected with the first combination areas on the same side; the extended flexible area is separated from the first bonding sheet through an isolating layer, and the isolating layer can be separated from the extended flexible area during bending; and the first rigid board and the first bonding sheet are respectively provided with a windowing area which is consistent with the original flexible area in position and size. On the basis of a conventional original flexible area, the extended flexible area is added, the overall width of the flexible area is enlarged, and the one-way bending radius of the flexible area is increased.

Description

technical field [0001] The invention relates to the technical field of PCB (Printed Circuit Board, printed circuit board), in particular to a rigid-flex board and a manufacturing method thereof. Background technique [0002] Rigid-flex board is a combination of flexible circuit board and rigid circuit board through pressing and other processes to form a flexible circuit board (Flexible Printed Circuit, FPC) and a printed circuit board (Printed Circuit Board, PCB). Circuit board; because the flexible and rigid board has both a certain rigid area and a certain flexible area, and the flexible area can be bent, it has great advantages in saving the internal space of the product, reducing the volume of the finished product, and improving product performance. [0003] However, the structure of the current rigid-flex board is as figure 1 As shown, the manufacturing method is usually as follows: first cut off the part of the hard board corresponding to the soft area 11 of the soft ...
