With free bend, winding, fold, can require any according to space layout and arrange, and arbitrarily moved and flexible in three dimensions, from
And reach the integration of components and parts assembling and wire connection.The volume of electronic product can be substantially reduced using FPC, electronics production is applicable
The need for product develop to high density, miniaturization, highly reliable direction.Therefore, FPC space flight, military affairs, mobile communication, laptop computer,
It is widely used on the fields such as computer peripheral equipment, PDA, digital camera or product.
Applications of the FPC on smart mobile phone or computer is mainly connection mainboard and display module, and then completes the biography of signal
Pass.To prevent that electromagnetic interference signal from interfering to FPC signal transmission, it will usually paste a floor in FPC signal line area
Diaphragm, plays a part of shielding interference, but the electromagnetic shielding diaphragm of prior art is simple in construction, electrical insulating property is poor,
Effectiveness and radiating effect are poor, influence FPC service behaviour.
Utility model content
In view of the shortcomings of the prior art, main purpose of the present utility model is to provide a kind of effectiveness
Good, the FPC diaphragms that electrical insulating property is good and thermal diffusivity is good.
To achieve the above object, the utility model provides following technical scheme：A kind of FPC diaphragms, including fold successively
The upper mould release membrance protective layer of conjunction, insulating barrier, electro-magnetic screen layer, heat dissipating layer, the first adhesive layer, support cushion, the second adhesive layer
And lower mould release membrance protective layer, FPC is arranged between electro-magnetic screen layer and upper mould release membrance protective layer.
It is preferred that, the electro-magnetic screen layer is copper foil tape.
It is preferred that, the heat dissipating layer is graphite flake.
It is preferred that, the surrounding of the graphite flake is provided with edge sealing.
It is preferred that, first adhesive layer is double faced adhesive tape.
It is preferred that, the support cushion is foam.
It is preferred that, it is provided with the upper mould release membrance protective layer and tears hand.
The utility model has the following advantages that relative to prior art, a kind of FPC diaphragms of the present utility model, and it passes through
Insulating barrier ensures FPC insulating properties, shields electromagnetic interference by electro-magnetic screen layer, it is ensured that FPC job stabilitys, and heat dissipating layer is protected
Hinder its thermal diffusivity, support cushion is mainly to ensure FPC and heat dissipating layer structural stability, the first adhesive layer and second gluing
Layer is two-sided tape, can play the good effect of being connected.FPC diaphragms of the present utility model can provide for FPC
Good electrical insulating property, electromagnetic wave shielding and thermal diffusivity, Stability Analysis of Structures, protective effect is comprehensive so that FPC being capable of steady operation.
