Problems solved by technology

[0005] However, for the above-mentioned first method, since there is a gap between the positioning hole (usually a round hole) and the positioning pin of the pull-soldering jig, the main FPC and the light source FPC may be caused by relative rotation. Misalignment, resulting in poor pull welding operation
For the above second method, due to the addition of a double-sided tape, it will increase the cost
In addition, the double-sided tape attached to the light source flexible circuit board is relatively small, so it is easy to cause the release paper to fall off, resulting in poor positioning of the main flexible circuit board and the light source flexible circuit board

Abstract

The invention provides a flexible circuit board assembly and an assembling method thereof. The flexible circuit board assembly comprises a first flexible circuit board, an adhesion piece and a second flexible circuit board. The first flexible circuit board is provided with a first surface, a second surface and a through hole for communicating the first surface with the second surface. The adhesion piece is arranged on the second surface and covers the through hole. The second flexible circuit board is arranged on the first surface. Part of the second flexible circuit board is glued with the adhesion piece through the through hole. Due to the adoption of the flexible circuit board assembly, the adhesion piece glued on the second surface of the first flexible circuit board is utilized to be simultaneously glued with the second flexible circuit board on the first surface of the first flexible circuit board. An area of the first flexible circuit board, which is overlapped relative to second flexible circuit board, is partially excavated to form the through hole, so that the second flexible circuit board on the first surface can be mutually glued with the adhesion piece on the second surface through the through hole. Therefore, the aim of mutual location of the first soft flexible circuit board and the second soft flexible circuit board is achieved.

Description

technical field [0001] The invention relates to a flexible circuit board combination, in particular to a flexible circuit board combination in a display. Background technique [0002] In recent years, due to the rapid development of the electronics and information industries, their related products have become increasingly sophisticated.
