Abstract
The invention discloses a finished product of a circuit board capable of reducing circuit board deformation and influencing a conduction force. The finished product comprises a flexible circuit board, a printing rubber ring and a rubber button, wherein the printing rubber ring is located between the flexible circuit board and the rubber button, the printing rubber ring is made of a printing rubber stencil, and an exhaust ditch is formed on the printing rubber ring. The finished product disclosed by the invention is applied to the printing rubber design for adhering the flexible circuit board, the exhaust ditch is formed on the printing rubber ring to reduce the deformation of the circuit board and influence the conduction ability, so as to improve the electric functions and the service life of the finished product of the circuit board, and a man-machine exchange user can have a pleasant experience.
Description
Technical field:
The present invention relates to flexible circuit board technical field, in particular to a kind of wiring board finished product that can reduce wiring board distortion and affect conducting strength.
Background technology:
Flexible circuitry board finished product is mainly used in the apparatus field of household electrical appliances button, computer key and various keypress function, and it realizes key assembling by printing glue and pasted in flexible circuit board by rubber key in flexible circuit board.In order to make flexible circuit board there will not be sensitive conducting or constant conduction, flexible circuit board adds print cushion rubber design as shown in Figure 1.
The print cushion rubber of prior art is all complete closed circular print cushion rubber, and as Fig. 5 and Fig. 6, this type of print cushion rubber ubiquity makes the air of rubber key inside and moisture discharge smoothly, and then has influence on the problem of wiring board distortion and ducting capacity.
Summary of the invention:
For the problems referred to above, improvement opportunity scheme of the present invention is as follows: a kind of wiring board finished product that can reduce wiring board distortion and affect conducting strength, comprise flexible circuit board, print cushion rubber and rubber key, described print cushion rubber is between flexible circuit board and rubber key, this print cushion rubber is made by printing glue web plate, and described print cushion rubber has exhaust ditch.
According to technique scheme, usually wanting rubber key to paste in flexible circuit board all needs to make print glue web plate design print cushion rubber, to reach, rubber key is assembled in flexible circuit board, realize button conducting function, print cushion rubber of the present invention all has exhaust ditch, this design effectively can get rid of the air and moisture that enter rubber key inside, thus reduces the distortion of wiring board and affect ducting capacity, promotes overall electric function.Every print cushion rubber has the design of exhaust channeling, all within the scope of the present invention, must not invade patent of the present invention.
The present invention designs for the print glue of sticking flexible wiring board, print cushion rubber has exhaust ditch can be reduced the distortion of wiring board and affect ducting capacity, thus promote electric function and the useful life of circuit board finished product, make the experience of the process that the user of man-machine exchange has a happiness comfortable.
As to the explanation being vented ditch in technique scheme, the quantity of described exhaust ditch is three, and the angle between described three exhaust ditches is 120 degree.Exhaust ditch is designed to three, and is the division of 120 degree in angle, the efficiency of exhaust can be made higher, and speed is faster.
As the explanation to rubber key in technique scheme, described rubber key is the shape that floor space is large, topside area is little, and described rubber key is transparent rubber.The top of described rubber key is provided with circular hole, and this circular hole coordinates with the bottom of device keys to be installed.The bottom of described rubber key is pasted with print cushion rubber and is connected.
Accompanying drawing illustrates:
Below in conjunction with accompanying drawing, the present invention is described further:
Fig. 1 is the fractionation structural representation of wiring board finished product;
Fig. 2 is the structural representation of rubber key;
Fig. 3 is flexible circuit board of the present invention and print cushion rubber mounting structure schematic diagram;
Fig. 4 is the B region structure for amplifying schematic diagram of Fig. 3;
Fig. 5 is flexible circuit board and the print cushion rubber mounting structure schematic diagram of prior art;
Fig. 6 is the a-quadrant structure for amplifying schematic diagram of Fig. 5.
Embodiment:
Composition graphs 1 to Fig. 4, a kind of wiring board finished product that can reduce wiring board distortion and affect conducting strength, comprise flexible circuit board 10, print cushion rubber 20 and rubber key 30, described print cushion rubber 20 is between flexible circuit board 10 and rubber key 30, this print cushion rubber 20 is made by print glue web plate, and described print cushion rubber 20 has exhaust ditch 200.
Composition graphs 4, the quantity of described exhaust ditch 200 is three, and the angle between described three exhaust ditches 200 is 120 degree.
Composition graphs 2, described rubber key 30 is the shape that floor space is large, topside area is little, and described rubber key 30 is transparent rubber.
Composition graphs 2, the top of described rubber key 30 is provided with circular hole, and this circular hole coordinates with the bottom of device keys to be installed.
Composition graphs 1 to Fig. 4, the bottom of described rubber key 30 is pasted with print cushion rubber 20 and is connected.
In practical operation, usually wanting rubber key 30 to paste in flexible circuit board 10 all needs to make print glue web plate design print cushion rubber 20, to reach, rubber key 30 is assembled in flexible circuit board 10, realize button conducting function, print cushion rubber 20 of the present invention all has exhaust ditch 200, this design effectively can get rid of the air and moisture that enter rubber key 30 inside, thus reduces the distortion of wiring board and affect ducting capacity, promotes overall electric function.Every print cushion rubber 20 has the design of exhaust ditch 200, all within the scope of the present invention, must not invade patent of the present invention.
Above content is only better embodiment of the present invention, and for those of ordinary skill in the art, according to thought of the present invention, all will change in specific embodiments and applications, this description should not be construed as limitation of the present invention.
