Embodiment
Below in conjunction with Figure of description, technical scheme of the present invention is described in detail.
With reference to Fig. 1, the electrostatic shielding body being applicable to image sensor chip of the present invention is made up of FPC material, mainly comprise shielding part 1, be provided with putting hole 2 in the center of shielding part 1, the shape of putting hole 2 is general consistent with the profile of the image sensor chip that will hold, both can be circle also can be rectangle, or other shapes, as a kind of preferred version, for the image sensor chip of general most rectangle, in the present embodiment, the shape of putting hole 2 is rectangle.
As shown in Figure 1; in order to realize image sensor chip and extraneous electrostatic isolation; be provided with at the periphery of putting hole 2 and extended upward by the body of shielding part 1 and the protective bulkhead 3 formed; as a kind of preferred version; protective bulkhead 3 can to putting hole 2 center low dip; when the shape of putting hole 2 is rectangle, the four edges of rectangle is respectively equipped with a protective bulkhead 3.
With reference to Fig. 1, be provided with by shielding part 1 body to the location division 4 that horizontal direction is formed in the edge of shielding part 1, location division 4 place is provided with ground connection location hole 5, this ground connection location hole 5 is for being fixed on the position of circuit board epigraph sensor chip periphery by shield of the present invention, and be connected with ground path, by Electro-static Driven Comb in the earth.
As a kind of preferred version, as shown in Figure 2, location division 4 is positioned at the corner location of shielding part 1, and for being become the auricle structure of part circular by shielding part 1 body extended, ground connection location hole 5 is arranged on center, location division 4.Such benefit, can provide larger-size ground connection location hole 5, makes location and installs more firm.
As a kind of preferred version, as shown in Figure 2, above-mentioned location division 4 and ground connection location hole 5 can be arranged on four corner locations of shielding part 1, namely cornerwise extended line of putting hole 2 can through the center of circle of ground connection location hole 5, so just whole shield can be located very well, in order to save material, the number of location division 4 is 2, can complete fixing.
In addition, as shown in Figure 2, the shape of protective bulkhead 3 is longer trapezoidal in base, and such benefit is, time shaping, be convenient to directly cut out a monoblock FPC material, then upwards turning down just can straight forming.
With reference to Fig. 3, the FPC material that the present invention uses is one side FPC material, be only covered with Copper Foil 6 at insulating barrier 7 upper surface, and surface is not provided with solder mask.So, the electrostatic of image sensor chip surrounding environment release can pass through surperficial copper foil layer by electrostatic leakage in grounded circuit, thus realizes the effect of electrostatic screen.
Above-described embodiment does not limit the present invention in any form, the technical scheme that the mode that all employings are equal to replacement or equivalent transformation obtains, and all drops in protection scope of the present invention.
