Abstract
The utility model discloses an FPC laminated structure which includes a substrate, copper foil, glue, and a covering film which are laminated successively. The FPC laminated structure also includes a silver paste layer which is directly coated on the covering film, and the covering film and the glue which are corresponding to a ground layer or a power supply layer on the copper foil are provided with at least one window, so the silver paste is connected with the copper foil. An electronic device possessing the FPC laminated structure is also disclosed. The FPC laminated structure has the smaller thickness, thus effectively realizing the impedance control and guaranteeing the sliding service lifetime.
Description
Technical field
The utility model relates to hardware electronic, particularly relates to a kind of FPC laminated construction and has the electronic equipment of this FPC laminated construction.
Background technology
In the consumption electronic product of bascule is arranged (for example lateral-sliding mobile phone), reach more than 150,000 times at bending state lower slider number of times in order to guarantee product, usually use individual layer FPC(flexible circuit board) carry out the electrical connection of two disparate modules.Along with its operating frequency of development, the transmission rate of smart mobile phone are more and more higher, during the interface protocols such as employing MIPI or MDDI, the impedance of its differential pair cabling requires to control in certain limit, and this just requires differential pair signal to the reference planes of one deck should be arranged.In existing technology; FPC when design usually can adopt increase again one deck or two layers Copper Foil as circuit as the reference plane; cost can be multiplied like this; increasing simultaneously the Copper Foil number of plies can make the thickness of FPC increase; cause sliding capability greatly to reduce, reduced times influence that FPC slides the life-span of product.And if do not do impedance Control at sliding area, can reduce properties of product
The utility model content
The purpose of this utility model is exactly in order to overcome the deficiencies in the prior art, a kind of FPC laminated construction is provided and has the electronic equipment of this FPC laminated construction, can effectively realize impedance Control with less FPC thickness.
