Abstract
The utility model discloses a kind of FPC plate, solve the problem that FPC plate is torn, its drip irrigation device is a kind of FPC plate, comprise substrate comprise Printing Department and and rib, described Printing Department is printed with copper foil circuit, described rib is arranged on Printing Department both sides, described rib is provided with several anti-ceasmas.The utility model has the advantages that by offering anti-ceasma on substrate, anti-ceasma reduces crackle and expands on substrate, prevents copper foil circuit from damaging, prevents FPC plate from tearing.
Description
Technical field
The utility model relates to a kind of flex circuit application and manufactures and designs field, and in particular, it relates to a kind of FPC plate.
Background technology
Flexible printed circuit board FPC (Flexible Printed Circuit Board) is the printed circuit made with flexible insulating substrate, has the advantage that many rigid printed circuit boards do not possess.Such as it can free bend, winding, folding, can require to arrange arbitrarily according to space layout, and moves arbitrarily at three dimensions and stretch, thus reaches components and parts and assemble the integration be connected with wire.Utilize FPC greatly can reduce the volume of electronic product, be suitable for the needs of electronic product to high density, miniaturization, highly reliable future development.Therefore, FPC is widely used on the fields such as space flight, military affairs, mobile communication, laptop computer, computer peripheral equipment, PDA, digital camera or product.FPC---Flexible Printed Circuit flexible circuit
Plate is also known as flexible circuit board; With mylar or polyimides for base material, Copper Foil forms circuit and the one made has height reliability, the printed circuit of excellent flexibility by being etched in.
But in practical set process, FPC plate is very thin, phenomenon is easily torn in not rounded degree of the slipping over position on FPC plate, affects the quality of FPC plate.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of FPC plate preventing tearing.
For achieving the above object, the utility model provides following technical scheme: a kind of FPC plate, comprise substrate comprise Printing Department and and rib, described Printing Department is printed with copper foil circuit, described rib is arranged on Printing Department both sides, described rib is provided with several anti-ceasmas.
As preferably, described rib is provided with stiffener, described stiffener is arranged around Printing Department.
As preferably, the right angle of described rib is provided with reinforcement part, and described reinforcement part is arc-shaped.
As preferably, described rib is provided with interface portion, the side of described interface portion has extended internally holddown groove, and described holddown groove end is provided with reinforced hole.
The utility model has following advantage compared to existing technology: by offering anti-ceasma on rib, reduces crackle and continues to expand on substrate, prevent copper foil circuit from damaging, prevent FPC plate from tearing, serve the effect improving FPC plate.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, substrate; 11, Printing Department; 12, rib; 3, installing hole; 4, stiffener; 5, anti-ceasma; 6, interface portion; 7, reinforcement part; 8, holddown groove; 9, reinforced hole; .
Embodiment
With reference to accompanying drawing, the utility model is described further.
As shown in Figure 1, a kind of FPC plate, comprise substrate 1 comprise Printing Department 11 and with rib 12, Printing Department 11 is printed with copper foil circuit, rib 12 is arranged on Printing Department 11 both sides, rib 12 is provided with several anti-ceasmas 5, the diameter of anti-ceasma 5 is preferably 3mm, once substrate 1 is torn, when crackle reaches anti-ceasma 5, crackle is torn anti-ceasma 5 wall and is namely ended, because crackle has touched air, not for the medium of crackle diffusion in anti-ceasma 5, crackle can not further extend to Printing Department 11; The both sides of Printing Department 11 are provided with stiffener 4 simultaneously, stiffener 4 is made of copper, when crack growth is to stiffener 4 position, if crackle also needs to extend the strength of materials that will overcome stiffener 4, and copper has good ductility is not easily torn, stiffener 4 made of copper has the effect of protection Printing Department 11, and the material that stiffener 4 also can have good ductility by other is made; Interior square position on substrate 1 is under the effect of external force, be easy to break, square position is on substrate 1 provided with the reinforcement part 7 of arcuation, square position refers to the right angle that interior angle is 270 degree, reinforcement part 7 is also applicable to the position that interior angle is greater than 180 degree simultaneously, reinforcement part 7 is the projections be made up of the material that the ductility such as copper are good, prevents substrate 1 from breaking in square position; Rib 12 is provided with interface portion 6, the side of interface portion 6 has extended internally holddown groove 8, holddown groove 8 end is provided with reinforced hole 9, the substrate 1 of FPC plate needs to be arranged on different positions, sometimes substrate 1 need to be arranged on there is high low head position on, and directly bend compared with interface portion 6, interface portion 6 bends from the position of holddown groove 8, make the elevated height of substrate 1 to higher, to adapt to more complicated installation requirements; The end of holddown groove 8 is provided with reinforced hole 9, when reinforced hole 9 prevents interface portion 6 to be bent upwards, at the end generation crackle of holddown groove 8 simultaneously; Substrate 1 is also provided with installing hole 3, and installing hole 3 matches with the installation projection of FPC plate installation site, plays the effect of fixing FPC plate.
The above is only preferred implementation of the present utility model, protection range of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection range of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection range of the present utility model.
