Abstract
A double-faced flexible circuit board with asymmetric copper thicknesses on two faces relates to the technical field of printed circuits. The double-faced flexible circuit board comprises a first polyimide cover film, a polyimide base material and a second polyimide cover film. The first polyimide cover film is adhered to the upper surface of the polyimide base material through an epoxy glue; the second polyimide cover film is adhered to the lower surface of the polyimide base material through the epoxy glue; and the upper surface of the polyimide base material is pressed with a first pure copper layer, the lower surface of the polyimide base material is pressed with a second pure copper layer, and the first pure copper layer is thicker than the second pure copper layer. The double-faced flexible circuit board is used to gather different applications on the same piece of product and can meet requirements of a user for different thicknesses on the same piece of product.
Description
Technical field
The utility model relates to the printed circuit technique field, is specifically related to the thick asymmetric double-faced flexible wiring board of a kind of two sides copper.
Background technology
Flexible PCB is that make take polyimides or polyester film as base material a kind of has height reliability, excellent flexual printed circuit board (PCB), the main use in a lot of products such as mobile phone, notebook computer, digital camera.Double-faced flexible wiring board product positive and negative circuit general in the prior art all is same thickness.But in some special application, the client needs the positive and negative circuit that different thickness is arranged.
Summary of the invention
The purpose of this utility model provides the thick asymmetric double-faced flexible wiring board of a kind of two sides copper, and it can be used in different application is collected in the same flake products, and can satisfy the client on the same flake products to the demand of different-thickness.
In order to solve the existing problem of background technology, the utility model is by the following technical solutions: it comprises the first polyimides coverlay 1, polyimide base material 2, the second polyimides coverlay 3; The first polyimides coverlay 1 is bonded in the upper surface of polyimide base material 2 by epoxy glue 4, and the second polyimides coverlay 3 is bonded in the lower surface of polyimide base material 2 by epoxy glue 4.
The upper surface pressing of described polyimide base material 2 has the first pure copper layer 5, and the lower surface pressing has the second pure copper layer 6.
Described the first pure copper layer 5 thickness are greater than the second pure copper layer 6.
The utlity model has following beneficial effect: can be used in different application is collected in the same flake products, and can satisfy the client on the same flake products to the demand of different-thickness.
Description of drawings:
Fig. 1 is structural representation of the present utility model.
Embodiment:
Referring to Fig. 1, this embodiment by the following technical solutions: it comprises the first polyimides coverlay 1, polyimide base material 2, the second polyimides coverlay 3; The first polyimides coverlay 1 is bonded in the upper surface of polyimide base material 2 by epoxy glue 4, and the second polyimides coverlay 3 is bonded in the lower surface of polyimide base material 2 by epoxy glue 4.
The upper surface pressing of described polyimide base material 2 has the first pure copper layer 5, and the lower surface pressing has the second pure copper layer 6.
Described the first pure copper layer 5 thickness are greater than the second pure copper layer 6.
This embodiment is aspect production technology, and is different from general double sided board, when producing a Copper Foil thickeied by copper plating process, and an other Copper Foil is not thickeied when electroplating via.
This embodiment can be used in different application is collected in the same flake products, and can satisfy the client on the same flake products to the demand of different-thickness.
