Description

The Rigid Flex of anti electromagnetic wave interference

Technical field:

The present invention relates to element technical field of safety protection, be specifically related to the Rigid Flex of anti electromagnetic wave interference.

Background technology:

The birth of FPC and PCB and development, expedited the emergence of this new product of Rigid Flex.Therefore, Rigid Flex is exactly flexible circuit board and rigid wiring board, through operations such as pressings, combines by related process requirement, the wiring board with FPC characteristic and PCB characteristic of formation.

Because Rigid Flex is the combination of FPC and PCB, the production of Rigid Flex should possess FPC production equipment and PCB production equipment simultaneously.First, circuit and the profile of Soft Bonding plate is drawn according to demand by Electronics Engineer, then, be issued to the factory that can produce Rigid Flex, through CAM engineer, associated documents processed, plan, then arrange FPC to produce line production required FPC, PCB product line and produce PCB, this two soft board and hardboard out after, according to the planning requirement of Electronics Engineer, by FPC and PCB through the seamless pressing of pressing machine, again through a series of details link, the finally Rigid Flex with regard to processing procedure.A very important link, should be Rigid Flex difficulty large, detailed problem is many, before shipment, generally all will entirely examine, because its value ratio is higher, in order to avoid allow both sides of supply and demand cause relevant benefit to lose.

Along with the fast development of science and technology, various new product is constantly weeded out the old and bring forth the new, and easy to use and carry easy demand in order to meet consumer, various electronic product is invariably towards light, thin, short, little development now; Wherein, semiconductor package part Semiconductor Package be a kind of semiconductor chip chip is electrically connected at one for base plate for packaging bearing part on, again with packing colloid this semiconductor chip coated of such as epoxy resin and bearing part, to protect this semiconductor chip and bearing part by this packing colloid, and avoid the infringement of extraneous aqueous vapor or pollutant, then set one as the covering member of metal-back in this packing colloid upper cover; Or only set one as the covering member of metal-back in this semiconductor chip and bearing part upper cover; to be protected this semiconductor chip as impaired in static discharge ESD... etc. from ectocine by this covering member; and the Electromagnetic Interference Electro-Magnetic Interference of inside and outside is stopped by this covering member; EMI and electromagnetic compatibility Electro-Magnetic Compatibility, EMC.

And the grounding system of existing packing component or system in package, the ground structure being located at outside covering member by this is electrically connected, then is electrically connected with system the earth, uses and prevents electromagnetic interference.

But the electromagnetic interference of equipment and electrostatic interference not only derive from external equipment, equipment itself can either produce a large amount of electromagnetic interference, such as, during circuit board access external equipment, when entering to plug, can produce static discharge effect.Producing electromagnetism electrostatic interference to equipment component, there is certain deficiency in traditional exterior shield mode.

Summary of the invention:

The object of this invention is to provide the Rigid Flex of anti electromagnetic wave interference, its design is ingenious, adopt the mode of inside and outside set, surface surrounding be provided with detect shielding conductor can near electromagnetism and electrostatic interference, and circuit board inside is also provided with barricade, can external electromagnetic interference be shielded, economical and practical.

In order to solve the problem existing for background technology, the present invention is by the following technical solutions: it comprises Rigid Flex body, circuit board Connection Block, circuit board integrated components, grounding assembly, detect shielding conductor, fixing pin, shielding board, the side of described Rigid Flex body is connected with circuit board Connection Block, the centre of Rigid Flex body is integrated with several circuit board integrated components, circuit board integrated components is electrically connected with circuit board Connection Block, the corner of described Rigid Flex body is provided with grounding assembly, detection shielding conductor is connected with between adjacent grounding assembly, detect shielding conductor and be connected to grounding assembly by fixing pin, the inside of described Rigid Flex body arranges and has shielding board, shielding board is connected with grounding assembly.

Its manufacture method: first according to designing draft cutting substrate, screen substrate, then the screen substrate cut and substrate were carried out compound, and then screen substrate surface carries out Copper Foil, and then the composite plate completing Copper Foil is carried out punching fluting, grounding assembly and detection shielding conductor are embedded in composite circuit board surface, finally carry out showing clean packaging.

The present invention has following beneficial effect: its design is ingenious, adopt the mode of inside and outside set, surperficial surrounding be provided with detect shielding conductor can near electromagnetism and electrostatic interference, and circuit board inside is also provided with barricade, can external electromagnetic interference be shielded, economical and practical.
