Abstract

The utility model discloses a film touch button which includes a button module group part, a module group control circuit part, and a connecting part arranged between the button module group part and the module group control circuit part. The button module group part includes buttons, the indium tin oxide of a button part, and a soft base material plate. The indium tin oxide of the button part is plated on the soft base material plate and a surrounding lead is plated on the indium tin oxide via a silver paste, and the surface is plated with an insulating protective film. The module group control circuit part includes a flexible circuit board, a touch chip, a communication interface communicating with a mainboard, and an indium tin oxide transparent conductive film. The touch chip is welded on the flexible circuit board. The indium tin oxide transparent conductive film is plated with a conductive silver paste and is pressed together with the flexible circuit board via a conductive hot melt adhesive. Channels on the touch chip are connected with the conductive silver paste. One button of the button part is corresponding to one channel in the touch chip. The button number can be reduced and increased at will, and the button pattern and the number are strong in generality, so the button change cost is low, and the stability is excellent.

Description

A kind of film touch key-press

Technical field

The utility model relates to film touch key-press technical field, is a kind of improvement technology of film touch key-press specifically.

Background technology

Existing touch key-press part must be made in indium tin oxide conductive film glass the inside, can't change the position of button part after the die sinking, can't be general to Different products different keys position, and also can't be general to different touch-control schemes and different keys quantity.

Summary of the invention

To above technological difficulties, in order well to overcome above defective, the purpose of the utility model provides a kind of film touch key-press; Processing conditions and production method are simple, and the quantity of button can arbitrarily increase and decrease, can be neatly according to the pattern of different touch-control conceptual design circuit boards; Button pattern and quantity highly versatile; Button change cost is low, workable, good stability.

A kind of film touch key-press; It is characterized in that: said film touch key-press comprises button module part and module control circuit part and the coupling part between the two; The button module partly comprises tin indium oxide, the soft backing material plate of button and button part; The tin indium oxide of button part is plated on the soft backing material plate and lead on every side is plated on the tin indium oxide with the silver slurry, also is coated with one deck insulating protective film on the surface, and the module control circuit partly comprises flexible PCB, touch chip, and the communication interface and the indium tin oxide transparent conducting film of mainboard communication; Touch chip is welded on the flexible PCB; On the indium tin oxide transparent conducting film, be coated with conductive silver paste and press together through conduction PUR and flexible PCB, the passage on the touch chip is connected with conductive silver paste, a passage in the button button correspondence touch chip partly.

The tin indium oxide of said button and button part is range upon range of state, and the insulating protective film at key induced part place is provided with the empty avoiding zone.

Said key induced part is provided with one, or two, or three, or more than three.

The utility model compared with prior art has the following advantages.

The utility model can be neatly adjusts according to client's touch key-press position and shape; The mould that need not reopen indium tin oxide conductive film glass just can be realized the function of film touch key-press; The quantity of button can arbitrarily increase and decrease; Can be neatly according to the pattern of different touch-control conceptual design indium tin oxide transparent conducting films, workable, good stability.
