The reinforcing plate is provided with a plurality of PI film layers and a plurality of AD adhesive layers, the thickness of the PI film layers is 25um, and the thickness of the AD adhesive layers is 25 um; AD glue film and PI rete alternate arrangement simplify the structure of stiffening plate.
Description
Technical Field
The utility model belongs to the technical field of the flexible copper-clad plate, specifically a stiffening plate for FPC.
Background
Currently, a reinforcing plate is frequently used when a Flexible Printed Circuit (FPC) is manufactured. The reinforcing plate is also called reinforcing plate, support plate, reinforcing plate and reinforcing rib, and its English name is Stiffeners. The reinforcing plate is widely used in the FPC, which is characterized by being light, thin, short and small, but abnormal losses such as punching, folding, and scars are easy to generate in the using process, so that the reinforcing plate mainly solves the flexibility of the flexible circuit board, improves the strength of the plugging part, and facilitates the integral assembly of the product. However, the conventional reinforcing plate has a complicated structure and high production cost.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a simplify the stiffening plate for FPC of structure.
In order to achieve the main purpose, the utility model provides a stiffening plate for FPC includes a plurality of PI retes and a plurality of AD glue films, and AD glue film is glued to an end face of PI rete, and the thickness of PI rete is 25um, and the thickness of AD glue film is 25 um; the AD glue layers and the PI film layers are arranged at intervals.
According to the scheme, the reinforcing plate comprises a plurality of PI film layers and a plurality of AD adhesive layers, the thickness of the PI film layers is 25um, and the thickness of the AD adhesive layers is 25 um; AD glue film and PI rete alternate arrangement simplify the structure of stiffening plate.
Drawings
The invention is further described with the aid of the accompanying drawings, in which, however, the embodiments do not constitute any limitation to the invention, and for those skilled in the art, other drawings may be obtained without inventive effort from the following drawings.
Fig. 1 is a schematic structural diagram of an embodiment of the PET substrate of the present invention.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.
Referring to fig. 1, a stiffening plate 100 for an FPC provided in this embodiment includes a plurality of PI film layers 1 and a plurality of AD adhesive layers 2, where the AD adhesive layers are bonded to an end surface of the PI film layers, the thickness of the PI film layers is 25um, and the thickness of the AD adhesive layers is 25 um; the AD glue layers and the PI film layers are arranged at intervals.
The AD glue layer is made of epoxy resin, or the AD glue layer is made of acrylic resin.
The reinforcing plate is provided with a plurality of PI film layers and a plurality of AD adhesive layers, the thickness of the PI film layers is 25um, and the thickness of the AD adhesive layers is 25 um; AD glue film and PI rete alternate arrangement simplify the structure of stiffening plate.
Finally, it should be emphasized that the present invention is not limited to the above-described embodiments, but only to the preferred embodiments of the invention, and is not limited to the embodiments, and any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included within the scope of the present invention.
