Technical field

The present invention relates to a kind of production technologies of control handle of game console key high resistant carbon oil plate.

Background technique

Its contact electric control part such as mobile phone key, control handle of game console key generally uses carbon oil plate, and carbon oil plate generally exists One layer of carbon oil of printing is made on common multilayer circuit board, conventionally produced carbon oil plate, only prints one layer of carbon oil as resistance Layer, conductive layer is conductive using the copper wire below circuit board, higher cost, prints carbon oil twice there are also a kind of currently on the market Mode, but it uses disposable high temperature to dry, and drying effect is poor, and because of heated fast, organic solvent quickly volatilizees to be made charcoal oil At undesirable generation, the wearability and temperature-coefficient of electrical resistance of charcoal oil reservoir such as bubble, crackle be a greater impact.

Summary of the invention

In view of the deficiencies of the prior art, the present invention provides a kind of production works of control handle of game console key high resistant carbon oil plate Skill.

Technical solution of the present invention is as follows: a kind of production technology of control handle of game console key high resistant carbon oil plate, including following Step:

(1) multilayer circuit board that drawing is completed successively is subjected to anti-welding silk noil print and wrongly written or mispronounced character silk-screen, wrongly written or mispronounced character silk-screen is complete again Carry out baking sheet；

(2) multilayer circuit board in step (1) is subjected to carbon oil printing using water film web plate, first carries out carbon oil conductive layer Printing, the resistance value of the first printing carbon oil is 10 Ω, and the first printing carbon oil viscosity is the carbon of 400-450dpas Oil is printed using vertical infrared heating furnace prebake 120 minutes under the conditions of 65 DEG C with a thickness of 3 μm.

(3) multilayer circuit board in step (2) is carried out to the printing of carbon oil resistive layer, the resistance value of the second printing carbon oil For 10000 Ω, the carbon oil that the viscosity of the second printing carbon oil is 200-250dpas is printed and is used again with a thickness of 3 μm Vertical oven is dried 120 minutes under the conditions of 175 DEG C.

(4) multilayer circuit board in step (3) is successively carried out to surface treatment and sharp processing.

(5) multilayer circuit board in step (4) is finally detected and quality control.

Specifically: the gap in the step (2) between the carbon oil layer of the first printing and the carbon oil layer of the second printing It is 20-30 μm.

Specifically: the carbon oil of the second printing is diluted using printing ink reducer in the step (2).

The beneficial effects of the present invention are: carbon oil layer first prints low resistance conductive layer, then low temperature preliminary drying using printing twice It is dry, the solvent in carbon oil is dried, the wearability and temperature-coefficient of electrical resistance of charcoal oil reservoir is improved, republishes high resistance measurement layer, It carries out high temperature to be fully cured, reduces charcoal oil because of heated fast, bubble caused by organic solvent quickly volatilizees, crackle etc. are undesirable It generates；Carbon oil conductive layer and carbon oil resistance lamellar spacing are big, prevent short circuit.

Specific embodiment

Technical scheme in the embodiment of the invention is clearly and completely described, it is clear that described embodiment is only It is a part of the embodiments of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, ordinary skill Personnel's every other embodiment obtained without making creative work, shall fall within the protection scope of the present invention.

A kind of production technology of control handle of game console key high resistant carbon oil plate, comprising the following steps:

(1) multilayer circuit board that drawing is completed successively is subjected to anti-welding silk noil print and wrongly written or mispronounced character silk-screen, wrongly written or mispronounced character silk-screen is complete again Carry out baking sheet；

(2) multilayer circuit board in step (1) is subjected to carbon oil printing using water film web plate, first carries out carbon oil conductive layer Printing, the resistance value of the first printing carbon oil is 10 Ω, and the first printing carbon oil viscosity is the carbon of 400-450dpas Oil is printed using vertical infrared heating furnace prebake 120 minutes under the conditions of 65 DEG C with a thickness of 3 μm.

(3) multilayer circuit board in step (2) is carried out to the printing of carbon oil resistive layer, the resistance value of the second printing carbon oil For 10000 Ω, the carbon oil that the viscosity of the second printing carbon oil is 200-250dpas is printed and is used again with a thickness of 3 μm Vertical oven is dried 120 minutes under the conditions of 175 DEG C.

(4) multilayer circuit board in step (3) is successively carried out to surface treatment and sharp processing.

(5) multilayer circuit board in step (4) is finally detected and quality control.

Gap in heretofore described step (2) between the carbon oil layer of the first printing and the carbon oil layer of the second printing It is 20-30 μm.

In the actual production process, carbon oil layer first prints low resistance conductive layer, then low temperature prebake, makes using printing twice Solvent drying in carbon oil, improves the wearability and temperature-coefficient of electrical resistance of charcoal oil reservoir, republishes high resistance measurement layer, carries out high Temperature is fully cured, and reduces charcoal oil because of heated fast, the undesirable generation such as bubble caused by organic solvent quickly volatilizees, crackle； Carbon oil conductive layer and carbon oil resistance lamellar spacing are big, prevent short circuit.

Above-described embodiment is merely to illustrate the present invention, and it is appropriate that any technical field those of ordinary skill does it Changes or modifications all should be regarded as not departing from the invention patent scope.
