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

[0062] Such as figure 1 As shown, it is a schematic flow chart of Embodiment 1 of a method for making a side button product of the present invention, comprising the following steps:

[0063] 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;

[0064] 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;

[0065] Step S3, punching the empty FPC board;

[0066] Step S4, with the conductive ink of the PFC empty board facing down, punching the FPC empty board;

[0067] Step S5, customizing the suction head for the automatic reinforcement machine according to the size o...

Embodiment 2

[0074] 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.

[0075] 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.

[0076] 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.

[0077] 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.

[0078] 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.

[0079] As a preferre...

Abstract

The invention discloses a method for making a novel side key product, comprising: making an FPC empty board, and printing silver paste, conductive carbon oil, and protective ink printed on the silver paste and carbon oil on the pad surface of the FPC empty board; Attach the thermosetting adhesive to the FPC empty board, use a round-head nail to position the special jig, and fix the jig on the desktop of the board; punch holes; place the conductive ink of the PFC empty board facing down, and The FPC empty board is punched; according to the size of the steel sheet, the suction head for the automatic reinforcement machine is customized, and the automatic reinforcement machine is used to make the FPC empty board fit the steel sheet, so as to obtain the FPC assembled and pasted with the steel sheet; One side of the above-mentioned FPC is turned over with the anti-folding line, so that the FPC wraps the steel sheet up and down; the FPC with the steel sheet reinforced is placed on the four-opening pressing machine for pressing, and the preset processing conditions are followed; after the steel sheet is pressed It is baked in a cabinet oven, and the product is covered with a release film during baking; after curing, it will be circulated according to the engineering design process, and finally the appearance of the finished product will be inspected by FQC / FQA, and the product will be packaged and shipped.

Description

technical field [0001] The invention relates to the technical field of flexible circuit board manufacturing, in particular to a method for manufacturing side key products. 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 recognized.
