It is folded, thickness is thin, small, connection is simple, convenient disassembly, easily solves the advantages that electromagnetic shielding (EMI).FFC can be selected arbitrarily
Wire count and spacing, are more convenient on line, greatly reduce the volume of electronic product, reduce production cost, improve production efficiency,
Be best suited between moving parts and mainboard, pcb board between pcb board, miniaturization electrical equipment in make data transmission cable it
With.FFC is widely used in the connection between various printer port of printer and mainboard, plotter, scanner, duplicator, sound equipment, liquid
Signal transmission and plate the plate connection of the products such as brilliant electric appliance, facsimile machine, various video disc players.In modern electrical equipment, almost nowhere
Do not exist.At present, existing FFC wire rods are needed after laminating in the compound one layer of hot melt adhesive of wire rod appearance.
But there are following defects for existing hot melt adhesive：
Existing FFC hot melt adhesive films fissipation factor is higher, signal transmission process, attenuation it is excessive, it is difficult to meet height and keep pouring in
Defeated requirement.
Utility model content
For overcome the deficiencies in the prior art, the purpose of this utility model is to provide a kind of hot melts with attenuating
Glued membrane, the hot melt adhesive film include release layer, PET film layer, adhesive and hot melt film layer successively from top to bottom, can be in FFC lines
Direct combination hot melt adhesive film on material, the hot melt adhesive film can significantly reduce the attenuation of signal transmission under high frequency condition, reduce FFC lines
The fissipation factor of the hot melt film of material.
The purpose of this utility model adopts the following technical scheme that realization：
A kind of hot melt adhesive film with attenuating is covered including release layer, PET film layer and hot melt film layer, the PET film layer
It covers in hot melt film layer, the release layer is covered on PET film layer, and the thickness of the hot melt film layer is 10-50 μm, the PET
The thickness of film layer is 12-50 μm, and the thickness of the release layer is 5-9 μm, is additionally provided between the PET film layer and hot melt film layer
Adhesive, the thickness of the adhesive is 3-6 μm.
Further, the hot melt film layer, adhesive are identical with PET film layer length, and the length of the release layer is more than
The length of PET film layer.
Further, the thickness of the PET film layer is 16-32 μm.
Further, it is described hot melt film layer for polyolefin film layer, improved polyalkene film layer, SBS and its hydride film layer,
One kind in SIS and its hydride film layer, butadiene-styrene rubber film layer.
Further, the hot melt adhesive layer is single layer structure layer or is covered for two layers or more than two layers of hot melt adhesive
Composite construction layer.
Further, the adhesive is layer of polyurethane.
Compared with prior art, the beneficial effects of the utility model are：
The hot melt adhesive film with attenuating of the utility model, the hot melt adhesive film from top to bottom successively include release layer,
PET film layer, adhesive and hot melt film layer, direct combination hot melt adhesive film, the hot melt adhesive film can significantly drop on FFC wire rods
The attenuation of signal transmission under low high frequency condition reduces the fissipation factor of the hot melt film of FFC wire rods.
