Problems solved by technology

At present, the outer conductive aluminum foil reinforcement boards used in FFC cables on the market are generally made of aluminum foil wheat grain materials that are fully covered with geothermal heat and laminated on the PET base layer. Although they can meet the production and application requirements to a certain extent, in the subsequent slotting , the tool is in direct contact with the aluminum foil layer, there will be a risk of aluminum chips or aluminum wire remaining, resulting in a short circuit during the use of the finished FFC cable product, which will eventually affect the cable signal transmission and signal transmission effect

preparation example Construction

[0023] A method for preparing an aluminum foil reinforcing plate applied to FFC cables, comprising the following steps,

[0024] S1: Coating the first hot-melt adhesive layer on the lower end surface of the first PET base material to form a bonding inner layer;

[0025] S2: Coating the second hot melt adhesive layer on the PET substrate interface of the aluminum foil Mylar to make the outer conductive layer;

[0026] S3: a plurality of second hot-melt adhesive layers of the outer conductive layer are attached to the upper end surface of the first PET base material of the same inner layer at intervals to make a reinforcing original plate;

[0027] S4: Grooving the upper end surface of the first PET base material bonded to the inner layer in the interval area between adjacent outer conductive layers to make a reinforcing plate with slots between adjacent outer conductive layers.

[0028] In the present invention, a plurality of outer conductive layers are bonded to the same bon...

Embodiment 1

[0045] The preparation of the laminated inner layer,

[0046] Step 1: Select a PET substrate with a thickness of 100 μm as the first PET substrate, and first perform chemical pretreatment on the first PET substrate, specifically, coat the surface of the first PET substrate with 0.5 μm acrylic emulsion coating The cloth is used as a buffer layer to reduce the easy attenuation of the surface properties of the substrate; the acrylic emulsion is specifically the acrylic emulsion produced by DuPont. Carry out electric discharge treatment to the first PET substrate again, strengthen the surface tension of the first PET substrate, the dyne value of the first PET substrate surface is 52dyn / cm;

[0047] Step 2: Coating the first hot-melt adhesive layer with a thickness of 30 μm on the end surface of the first PET substrate by using a comma doctor blade coating method to form a bonding inner layer. Specifically, a comma doctor blade is used to coat the hot melt adhesive layer evenly an...

Embodiment 2

[0058] The preparation method and process of the second embodiment are the same as that of the first embodiment, only the thickness of the second PET base film is changed, specifically, the thickness of the second PET base film is 75mm, and the thicknesses of other constituent materials are the same as those of the first embodiment.

Abstract

A method for preparing an aluminum foil reinforcement board applied to FFC cables and the reinforcement board. The present invention relates to the technical field of reinforcement boards. S1: Coating a first hot-melt adhesive layer on the lower end surface of a first PET base material to manufacture Laminating the inner layer; S2: Coating the second hot-melt adhesive layer on the PET substrate interface of the aluminum foil Mylar to make the outer conductive layer; S3: Laminating the second hot-melt adhesive layers of multiple outer conductive layers at intervals On the upper end surface of the first PET base material of the same laminated inner layer, a reinforcing original plate is made; S4: slotting is performed on the laminated inner layer in the interval area between adjacent outer conductive layers to form adjacent outer conductive layers. Reinforcing plate with slots between conductive layers. During the grooving process of the reinforced original plate, the cutting position of the cutter is located in the interval area between the adjacent outer conductive layers, so that the cutter only contacts the inner layer, and the cutter does not contact the metal layer of the outer conductive layer, which is reasonable Use the reserved space to reduce the residue of metal shavings and metal wires, and reduce the risk of short circuit and abnormal display image quality during the use of the FFC line.

Description

technical field [0001] The invention relates to the technical field of reinforcement boards, in particular to a method for preparing an aluminum foil reinforcement board used in FFC cables and the reinforcement board. Background technique [0002] FFC flexible flat cable is a kind of flat copper wire with PET insulation material and extremely thin tinned plate. At present, the outer conductive aluminum foil reinforcement boards used in FFC cables on the market are generally made of aluminum foil wheat grain materials that are fully covered with geothermal heat and laminated on the PET base layer. Although they can meet the production and application requirements to a certain extent, in the subsequent slotting , The tool is in direct contact with the aluminum foil layer, there will be a risk of aluminum scrap or aluminum wire remaining, resulting in a short circuit during the use of the finished FFC cable product, which will eventually affect the cable signal transmission and...
