Embodiment approach

[0027] Preferably, after the step B, visual inspection and tension inspection are also included. The visual inspection here is to check whether the FPC is scratched during the operation process. The main result of the flexible printed circuit board connection is the reference continuity and reliability. Whether the performance is good or not, the tensile inspection standard is generally given according to customer needs. As an implementation manner, the tensile force required by the FPC connection structure may be greater than 200 g / cm.

[0028] In the manufacturing method of the flexible printed circuit board connection structure, the electrical connection between the module FPC and the FPC is connected by ACF, which has good high temperature stability, low thermal expansion coefficient, low moisture absorption, and excellent conductivity; it can be used according to the FPC gold finger Conductive gold balls with different diameters are selected for the Pitch value between th...

Abstract

The invention discloses a connecting structure of a flexile printed circuit board, which comprises a module flexile printed circuit board, a connecting flexile printed circuit board and an anisotropic conducting membrane, wherein one end of the module flexile printed circuit board has a first golden finger; one end of the connecting flexile printed circuit board has a second golden finger corresponding to the first golden finger; and the anisotropic conducting membrane electrically connects the first golden finger and the second golden finger. The invention also provides a method for manufacturing the connecting structure of the flexile printed circuit board. In the invention, the second golden finger of the connecting flexile printed circuit board and the first golden finger of the module flexile printed circuit board are electrically connected by the anisotropic conducting membrane, so the connecting part of the conventional module flexile printed circuit board is prolonged in a disguised manner. Thus, under the condition that the module flexile printed circuit board is not required to be redesigned, the connecting structure of the flexile printed circuit board is applied to mobile phones with different structures, the time and material wastes in FPC structure design are avoided and the cost is reduced.

Description

【Technical field】 [0001] The invention belongs to the field of flexible printed circuit boards, and in particular relates to a flexible printed circuit board (Flexible Printed Circuit, FPC for short) connection structure and a manufacturing method. 【Background technique】 [0002] In the design of mobile phones, for different models and different structures (such as straight board, slide cover, flip cover, etc.), it is necessary to design the corresponding LCD module. The design of the LCD module mainly includes: 1. The collocation of LCD and driver chips ; 2. The shape and structure of the flexible printed circuit board; 3. The design of the external components. Among them, the most complicated is the structure design of FPC, because the liquid crystal display module is connected with the main board of the mobile phone through the FPC, and the position, shape and length of the components on the FPC directly determine the design of the main board of the mobile phone. If the ...
