And reach the integration of components and parts assembling and wire connection.The volume of electronic product can be substantially reduced using FPC, electronics be applicable and be produced
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 electromagnetic interference signal from being interfered to the signal transmission of FPC, it will usually paste a floor in the signal line area of FPC
Electromagnetic shielding diaphragm, plays a part of shielding and disturbs, but the simple structure of the electromagnetic shielding diaphragm of prior art, electromagnetism
Shield effectiveness is poor, influences the service behaviour of FPC.
Utility model content
In view of the shortcomings of the prior art, main purpose of the present utility model is that a kind of effectiveness of offer is good
And protection is comprehensively electromagnetically shielded diaphragm.
To achieve the above object, the utility model provides following technical scheme：One kind electromagnetic shielding diaphragm, including according to
The insulating barrier of secondary overlapping, FPC, electro-magnetic screen layer, heat dissipating layer, the first adhesive layer, support cushion and the second adhesive layer, it is described
The hot melt adhesive layer being generally aligned in the same plane with FPC is additionally provided with electro-magnetic screen layer, the insulating barrier is connected with hot melt adhesive layer.
Preferably, the electro-magnetic screen layer is copper foil tape.
Preferably, the heat dissipating layer is graphite flake.
Preferably, first adhesive layer is double faced adhesive tape.
Preferably, the support cushion is foam.
Preferably, the two sides of the electromagnetic shielding diaphragm is provided with mould release membrance protective layer.
The utility model has the following advantages that one kind of the present utility model is electromagnetically shielded diaphragm relative to prior art,
