The technological process of processing high-frequency signal FFC glued membrane is: be first netted dielectric layer or a dielectric layer for plated metal in the printing of bottom upper surface, namely bottom and dielectric layer bonded to each other become ground floor body; Then, upper epidermis is formed at the upper surface applying hot melt adhesives of interlayer, i.e. interlayer and the upper epidermis layer second layer bonded to each other body, finally, synthesizes the finished product of described high-frequency signal FFC glued membrane by ground floor body and second layer body by the intermediate layer of being made up of compound adhesive material mutually.
A kind of technological process of processing high-frequency signal FFC glued membrane is: first respectively metal dust is become liquid with compound adhesive uniform stirring; Then, upper epidermis is formed at the upper surface applying hot melt adhesives of interlayer, namely interlayer and upper epidermis compound form ground floor body, then, the dielectric layer be made up of liquid metal dust and the intermediate layer be made up of liquid compound adhesive are combined into the first composite layer body mutually, finally, by bottom, the first composite layer body and ground floor body are combined into the finished product of described high-frequency signal FFC glued membrane mutually.
Beneficial effect of the present invention: because the technical program passes through bottom, dielectric layer, intermediate layer, interlayer and upper epidermis sequentially pass through the high-frequency signal FFC film that coating machine laminating is formed successively, in this bonding process, do not need artificial participation to fit, whole operation is formed by the disposable laminating of coating machine, this high-frequency signal FFC film can use as glued membrane of FFC, simultaneously disposable fit into high-frequency signal FFC after do not need any auxiliary material of fitting.。Decrease the fraction defective caused because pasting auxiliary material below.
Below in conjunction with drawings and Examples, technical scheme of the present invention is described in further detail.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of high-frequency signal FFC glued membrane of the present invention.
Embodiment
In order to make technical problem to be solved by this invention, technical scheme and beneficial effect clearly, understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
Please refer to shown in Fig. 1, below in conjunction with the first embodiment, a kind of high-frequency signal FFC glued membrane is described, it comprises bottom 1, dielectric layer 2, intermediate layer 3, interlayer 4 and upper epidermis 5.
PETG chemical formula is-OCH2-CH2OCOC6H4CO-English name: polyethyleneterephthalate, is called for short PET.FFC, the abbreviation of flexible flat cable.
Described bottom 1 and interlayer 4 are made up of PET material respectively.Described upper epidermis 5 is made up of hot melt adhesive material.Described intermediate layer 3 is made up of compound adhesive material.Described dielectric layer 2 is formed in bottom surface by the powder coated of aluminium, carbon, copper and silver, or aluminium, carbon, copper, silver slurries be that netted silk-screen is formed in bottom surface, or aluminium, carbon, copper, silver electroplate formed in bottom surface.
Dielectric layer 2 is fitted in the upper surface of bottom 1, and described intermediate layer 3 is fitted in dielectric layer 2 upper surface, and described interlayer 4 is fitted in above intermediate layer 3, and described upper epidermis 5 is fitted in above interlayer 4.
In the present embodiment, the technological process of described high-frequency signal FFC glued membrane is: be first printed with netted dielectric layer 2 at bottom 1 upper surface, namely bottom 1 and dielectric layer 2 bonded to each other become ground floor body; Then, the upper surface of interlayer 4 will be coated with the upper epidermis 5 of PUR, i.e. interlayer 4 and upper epidermis 5 bonded to each other layers of second layer body, finally, synthesize the finished product of described high-frequency signal FFC glued membrane by ground floor body and second layer body by the intermediate layer 3 of being made up of compound adhesive material mutually.In this embodiment, also metallic aluminium, carbon, copper, silver can be formed dielectric layer 2 by electroplating technique plating in bottom surface.
