Abstract
The utility model discloses a polyimide insulation hot-melt adhesive film structure of an FFC (flexible flat cable), which is characterized in that the structure comprises a layer of polyimide film; and the surface of the polyimide film is coated with a layer of fire-proof insulation hot-melt adhesive. The polyimide insulation hot-melt adhesive film structure adopts the polyimide film to replace a PET (positron emission tomography), and the polyimide film can endure the high temperature of more than 200 DEG C without deformation, therefore, the high-temperature resistance of the insulation adhesive film is greatly improved, and the demands for different cables are satisfied by adjusting the thickness of the polyimide film and the fire-proof insulation hot-melt adhesive.
Description
Technical field
The utility model relates to the sticking structure on a kind of FFC line surface.
Background technology
The English full name of FFC is: Flexible Flat Cable, it is flexible flat cable, it is a kind of with PET insulating material and zinc-plated flat copper wire as thin as a wafer, by the new types of data cable that the pressing of high-tech automation equipment production line forms, have softness, random bending fold, thin thickness, advantages such as volume is little, connection is simple, convenient disassembly, high-temperature space use.Can select lead number and spacing arbitrarily, make on line more convenient, significantly reduce the volume of electronic product, reduce production cost, enhance productivity, be suitable between moving-member and the mainboard most, pcb board between the pcb board, make the usefulness of data transmission cable in the miniaturization electrical equipment equipment.
The structure of the insulation glued membrane use that existing FFC flexible flat uses is PET (polyester film) coating certain thickness fire-proof insulation glue, and using shortcoming is that PET can produce contraction under the state more than 105 ℃, influences the stability in use of FFC wire rod under the condition of high temperature
The utility model content
The purpose of this utility model is, overcomes the deficiencies in the prior art, proposes a kind of hot melt adhesive film structure of new FFC line, still keeps stable under the state of higher temperatures.
The technical solution adopted in the utility model is as follows:
The polyimide insulative hot melt adhesive film structure of FFC line comprises one deck PI (polyimides) film, and polyimide film surface coated has one deck fire-proof insulation PUR.The direct pressing of described hot melt adhesive film insulation glue-line pastes conductor moulding FFC flexible flat cable.
The beneficial effects of the utility model are: adopt the PI film to replace PET, because the PI film can tolerate the high temperature more than 200 ℃ and can not be out of shape, thereby improved the heat resistance of insulation glued membrane greatly, can satisfy the requirement of different wire rods.
Description of drawings
Fig. 1 is the structural representation of the utility model hot melt adhesive film.
Embodiment
The polyimide insulative hot melt adhesive film structure of FFC line comprises one deck PI (polyimides) film 1, and the PI film surface is coated with one deck fire-proof insulation PUR 2.The direct pressing of described hot melt adhesive film glue-line pastes conductor moulding FFC flexible flat cable.
Claims (2)
1.FFC the polyimide insulative hot melt adhesive film structure of line is characterized in that: comprise one deck polyimide film, polyimide film surface coated has one deck fire-proof insulation PUR.
2. hot melt adhesive film structure as claimed in claim 1, the direct pressing of described hot melt adhesive film paste conductor moulding FFC flexible flat cable.
