Description
Affiliated technical field
The present invention relates to the keyboard of household appliances or various communication terminal machines, specifically a kind of touch inductive circuit board and manufacture method thereof.
Background technology
Various communication terminal machines such as household appliances in the past and slide phone, slip lid PDA, computer; be suitable for the touch wiring board of keyboard; the insulating substrate surface of adopting insulator such as PET or acryl and making; connect into the touch part; the circuitry lines that constitutes with the outside inductor that touches perceptual signal and connecting portion; after silver (Ag) printing, the insulating protective film engineering of Xing Chenging and making in the circuit board.The touch wiring board of above-mentioned manufacturing is that the static content mode as can be known that takes place in human body starts.Externally under the inductor connection status, the user conductor wire with finger touch and touches the variation that part has static content, and at this moment, the static content signal that external sensor control touches part changes, the signal that output control starts.
Operate above-mentioned touch wiring board and be generally used for 3mm following plastics or acryl, the static content of consumer's touch part when the touch of above-mentioned printing conductive line partly contacts with finger altered a great deal after perhaps sticked the following glass back of 5mm.
Making touch inductive circuit board is silver powder, and synthetic resin is deployed into silver-colored printing ink, becomes conductor wire with this ink printing, because residual resistance is very high, the reception and registration speed of its electric current and signal is slow.In addition, in the winding and the sweep synthetic resin sheet instability of product performance, therefore the circuit part of conductor wire is easy to damage in assembling or in the middle of using.The bad control of use amount with the silver powder of synthetic resin allotment increases manufacturing cost.
Summary of the invention
The objective of the invention is to solve the deficiency of above-mentioned technology; metallic film at insulating substrate surface laminated or plated film forms by corrosion treatment; the conducting wire plate that part forms with being connected the connection of perception touch signal external sensor will be touched; perhaps insulating substrate surface coating nonferrous metal and after forming above-mentioned conducting wire plate; touch part and connecting portion with the printing of carbon liquid diaphragm after, the engineering of above-mentioned conducting wire plate surface formation insulating protective film and making.After the resistive ink of handling with water-soluble metal on the insulating substrate surface is printed as diaphragm; the touch part of above-mentioned inchoate diaphragm part plated film nonferrous metal or plated film connects and the conducting wire plate of formation with the external sensor that is connected the perception touch signal; then after the resistive ink of handling with water-soluble metal is removed; after touch part and connecting portion print with carbon liquid diaphragm, the touch inductive circuit board and the manufacture method thereof of conducting wire plate surface formation insulating protective film.
The present invention solves the problems of the technologies described above the technical scheme of being taked: touch inductive circuit board and manufacture method thereof; on the insulating substrate surface; use copper; silver; gold; aluminium selects one; carry out lamination or plated film and become the engineering of metallic film; become behind the diaphragm and dry engineering with the corrosion ink printing; after carrying out the corrosive agent injection above the metallic film; the above-mentioned part that does not form diaphragm is by the engineering of corrosion treatment striping from the insulating substrate; behind alkaline aqueous solution cleaning protection film and residual corrosive agent; partly conductor wire and the dry engineering that forms with being connected the external sensor connection of controlling touch signal will be touched; the touch of above-mentioned conductor wire part or connecting portion be with printing of carbon liquid and dry engineering, and above-mentioned conductor wire surface and do not form current-carrying part above the insulating substrate with the insulating protective film printing and the engineering of drying in addition.
Touch inductive circuit board and manufacture method thereof; often surperficial in insulation; metallized resistive ink printing diaphragm and dry engineering; do not form the diaphragm part in the surface to insulating substrate; use copper; silver; gold; aluminium selects one; electroplate or plated film; part forms conductor wire with being connected the external sensor connection of controlling touch signal engineering will be touched; said protection film is cleaned the engineering of the dry conductor wire in back with warm water; at the touch of above-mentioned conductor wire part or connecting portion with printing of carbon liquid and dry engineering, and above-mentioned conductor wire surface and do not form current-carrying part above the insulating substrate with the insulating protective film printing and the engineering of drying in addition.
The silver-colored printing ink that the present invention makes of allotments such as powder synthetic resin, on insulating substrate, directly print and form the touch inductive circuit board of conductor wire, residual resistance is very low, electric power consumption seldom, current flow conveys a message rapidly, winding and crooked heat-resisting, suitable temperature range are big, and the present invention makes easily, cost is low, long service life.
