Abstract

The utility model discloses a three-layer double-sided copper foil FCCL (Flexible Copper Clad Laminates) structure which comprises an adhesive layer, and a first copper foil layer and a second copper foil layer which are arranged at both sides of the adhesive layer, wherein the adhesive layer has the thickness of 8 to 120mum, and the first copper foil layer and the second copper foil layer have the thicknesses of 9 to 110mum. Due to structural innovation of the FCCL material of the three-layer double-sided copper foil FCCL structure, the coating and compounding need to be carried out only once in the machining process, so that the complexity and difficulty of the existing process flow are obviously reduced, and the production efficiency and the yield are greatly improved. The flexible copper clad with three-layer double-sided copper foil in the structure has high size stability, and has good flexibility performance. Moreover, the adhesive layer with excellent insulating property is adopted to replace an insulating material PI (Polyimide), so that the production cost of the FCCL is greatly reduced, the cost can be reduced by about 20 to 25 percent, and meanwhile, the manufacturing cost of a FPC (Flexible Printed Circuit) is effectively reduced. Therefore, the three-layer double-sided copper foil FCCL structure is beneficial to wide application of the FPC in the fields of civil electronic product, military product, mechanical appliance, space flight and aviation and the like.

Description

A kind of FCCL structure of three layers of two-sided Copper Foil

The technology contents of the utility model is:

A kind of FCCL structure of three layers of two-sided Copper Foil, its characteristic comprise adhesive layer and first copper foil layer, second copper foil layer of being located at the adhesive layer both sides, and the thickness of said adhesive layer is 8-120um, and the thickness of said first copper foil layer, second copper foil layer is 9-110um.

A kind of production equipment of FCCL structure of three layers of two-sided Copper Foil, its characteristic comprise first bin, encapsulating machine, glue spreader, first baking oven, second bin that set gradually, are laminated with machine and rewinding frame; First bin wherein is used to install the Copper Foil coiled material of first copper foil layer; Second bin is used to install the Copper Foil coiled material of second copper foil layer.

Its further technical scheme is: also comprise second baking oven of being located at rewinding frame side.

Its further technical scheme is: also comprise frame, described frame is provided with aforesaid encapsulating machine, glue spreader, first baking oven and is laminated with machine, and described second baking oven is located at the tail end of frame, and described first bin is located at the head end of frame.Wherein, the length of second baking oven can increase according to actual needs, and the length of first baking oven decides according to the recombination velocity of Copper Foil and the time of first heating.

Its further technical scheme is: the top of said frame is provided with aforesaid second bin.

The utility model beneficial effect compared with prior art is: the utility model FCCL material; Because structural innovation; Only need take once to be coated with (being gluing), once-combined (promptly being laminated with) man-hour adding; Significantly reduced the complexity and the difficulty of existing technological process, enhanced productivity greatly and yields.The flexibility coat copper plate of three layers of two-sided Copper Foil of the utility model, dimensional stability is high, and has flexural property preferably.In addition, owing to adopt the adhesive layer (because adhesive oven dry back forms) with good insulation performance to substitute insulating materials PI, greatly reduce the production cost of FCCL, can reduce cost is about 20-25%, has also reduced the manufacturing cost of FPC simultaneously effectively.Thereby help FPC in extensive applications such as consumer electronic product, military use product, medicine equipment, space flight and aviation.

Below in conjunction with accompanying drawing and specific embodiment the utility model is further described.
