Embodiment
By describing technology contents of the present utility model, structural feature in detail, being realized object and effect, below in conjunction with execution mode and coordinate accompanying drawing to be explained in detail.
Refer to Fig. 1, a kind of flexible PCB that present embodiment provides, comprise the first conductive layer, the second conductive layer, the first insulating barrier, the second insulating barrier, the 3rd insulating barrier 2, the first circuit module, second circuit module, connection line, between described the first conductive layer and the second conductive layer, be provided with the 3rd insulating barrier 2, described the first circuit module, second circuit module is arranged on the first conductive layer, described the first insulating barrier is arranged on the first conductive layer, described the second insulating barrier is arranged on the outside of the second conductive layer, described connection line is arranged on the 3rd insulating barrier 2, through the first conductive layer and the first circuit module, second circuit module realizes and being electrically connected to, on described the 3rd insulating barrier 2, a junction is also set, one end of described connecting portion is connected with the connection line on described flexible PCB, and the other end is connected with the connecting portion on another flexible PCB.In the utility model, described connecting portion can be arranged at an end of described flexible PCB, also can be arranged at two ends of flexible PCB, further, its can projection or depression be arranged at the end of the 3rd insulating barrier 2.Described in each, connecting portion one end is connected with each circuit of described flexible PCB, the other end is for being connected with the connecting portion on another flexible PCB, so, described connecting portion not only can play the connection between two flexible PCBs, can also play the connection between two flexible PCBs, connect simple and convenient, and stable connection.
The improvement of above-mentioned execution mode has, described connecting portion comprises Copper Foil 3 and coverlay 4, and described Copper Foil 3 one end faces are attached at the 3rd insulating barrier 2 one end faces, and coverlay 4 one end faces are attached at the other end of Copper Foil 3, described coverlay 4 is provided with a breach 5, and described breach 5 covers glue to be processed.The relative attenuation of gross thickness that described breach 5 makes connecting portion breach 5 places is set, thereby intensity diminishing, and reaches the controlled object of bending of connecting portion, is protection Copper Foil 3, and the position that breach 5 is set at coverlay 4 sprays liquid photo-imaging solder resist and covers glue and process.
Consult shown in accompanying drawing, in figure, shown the structural representation that described flexible PCB is connected with another flexible PCB 1.Flexible PCB is when being connected with another circuit board, and the field strength relatively thin due to connecting portion breach 5 place's thickness is little, therefore bending nature produces from here, for guaranteeing good bending effect, the width of described breach 5 is that any distance in 2-8mm is advisable.
In an execution mode of the present utility model, described Copper Foil 3, for calendering copper or cathode copper, there is no very large difference in the two result of use, therefore can select applicable Copper Foil 3 according to the application of actual conditions.
The foregoing is only embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or conversion of equivalent flow process that utilizes the utility model specification and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
