Problems solved by technology

[0004] Therefore, this type of FPC has a special structure, and it needs to use conductive carbon oil and silver paste as the medium of signal transmission. At the same time, it needs to attach multiple small steel sheets at equal distances on the FPC. Pressing, and the conventional steel sheet sticking / pressing method cannot meet the requirements of product flatness and voltage stability

Embodiment 1

[0064] Such as figure 1 As shown, it is a schematic flow chart of Embodiment 1 of a manufacturing method of a novel side button product of the present invention, comprising the following steps:

[0065] Step S1, making an empty FPC board according to the conventional FPC production process, and printing silver paste for conduction, conductive carbon oil for stable resistance, printing on silver paste and conductive carbon on the pad surface of the FPC empty board The protective ink on the oil can realize the printing of conductive ink on the FPC empty board;

[0066] Step S2, attaching the thermosetting adhesive to the FPC empty board, using a round-head nail positioning special jig, and fixing the jig on the board desktop;

[0067] Step S3, punching the empty FPC board;

[0068] Step S4, with the conductive ink of the PFC empty board facing down, punching the FPC empty board;

[0069] Step S5, customizing the suction head for the automatic reinforcement machine according t...

Embodiment 2

[0076] A method for manufacturing a flexible board of a side button product, mainly including lamination structure design, tool design, flatness control, and a method for manufacturing a side button flexible board.

[0077] The laminated structure design includes that the designed flexible board is composed of steel sheet reinforcement, thermosetting glue, cover film 1, double-sided panels, and cover film 2 in sequence.

[0078] Specifically, the flexible board (corresponding to the FPC in Embodiment 1, both of which are components used to manufacture side key products) is composed of a reflexed area, a circuit connection area and a finger area.

[0079] As a preferred embodiment, the size of the cover film 1 and the cover film 2 are consistent, both of which are 1 / 2 mil thick in PI and 15 μm thick in glue.

[0080] As a preferred embodiment, the reinforcement of the steel sheet is 0.4-0.6mm thick, and the interval between the steel sheets is 0.5-1.0mm.

[0081] As a preferre...

Abstract

The invention discloses a manufacturing method for a novel side key product, and the method comprises the following steps: manufacturing an FPC blank board, and printing silver paste, conductive carbon oil and protective ink printed on the silver paste and the carbon oil on a bonding pad surface of the FPC blank board respectively; enabling a thermosetting adhesive to be attached to the FPC blankboard, enabling a special jig to be positioned through round head nails, and enabling the jig to be fixed to a board attaching table top; performing punching; enabling the conductive ink surface of the PFC blank board to face downwards, and punching the FPC blank board; customizing a suction head attached by an automatic reinforcing machine according to the size of the steel sheet, and attaching the FPC blank plate to the steel sheet by adopting the automatic reinforcing machine to obtain an FPC assembled with the attached steel sheet; enabling gone side of the FPC to be turned over along withthe reverse folding line, so that the FPC wraps the steel sheet up and down; putting the FPC pasted with the steel sheet reinforcement on a four-opening pressing machine for pressing, and following apreset processing condition; after the steel sheets are pressed, adopting a cabinet type drying oven for baking, wherein a release film is cushioned under a product during baking; after curing is completed, performing circulation according to the engineering design process, and finally obtaining a finished FQC / FQA; checking the appearance, and performing packaging and shipment.

Description

technical field [0001] The invention relates to the technical field of flexible circuit board manufacturing, in particular to a method for manufacturing a novel side key product. Background technique [0002] In the current technology, side key products mainly transmit signals by pressing the DOM sheet. Traditional side key products need to have side key slots on the housing. The key slots are composed of outer slots (some include middle slots) and inner slots. , the shell is uneven and there are gaps in the keyway, so the waterproof function cannot be achieved. [0003] In the current consumer market, the requirement for the side button FPC is that it cannot damage the frame structure of the mobile phone, and can be directly attached to the frame. By touching the frame, the slight deformation of the frame is converted into a recognizable voltage signal by means of pressure sensing, and then Through system collection and processing, the user's touch operation can be recogni...
