Embodiment
Below in conjunction with embodiment and accompanying drawing, the technical solution of the utility model is clearly and completely described.
In the first enforcement of the present utility model, the body 1 of flexible PCB is non-bar shaped flexible PCB, Figure 2 shows that a square flexible PCB, on non-bar shaped flexible PCB body, prints strip circuit; Being distributed on described non-bar shaped flexible PCB body of described strip circuit complications; Described in cutting, non-bar shaped flexible PCB body can obtain tortuous strip circuit plate, and described strip circuit plate is corresponding with described strip circuit.
Described square flexible PCB is provided with position or perhaps the range of linearity for cutting corresponding with described strip circuit, in the time of printed circuit design and production, just reserve this range of linearity, in the present embodiment, concrete cutting is as follows: in vertical (not necessarily the leaveing no choice but vertical) direction on described square two relative limits, carry out cutting or cutting formation cut line 2, each cut line 2 can not run through described two relative limits, that is to say, described cut line 2 can not be divided into two described flexible PCB, and what described dotted line 3 represented is the part not running through.The position of cut line 2 correspondences is exactly the position for cutting of reserving, and described cutting or cutting hocket the other way around.Folding described strip circuit plate forms linear strip circuit plate and/or needed shaped as frame strip circuit plate.
Fig. 3 shows the method for folding first step of utilizing the flexible PCB of the utility model making to be folded into the strip circuit plate of wanting.Circuit board line centered by cut line 2 is carried out to doubling, form the shape shown in Fig. 4.
Continue to fold for the second time according to the folding direction shown in Fig. 4, form the shape shown in Fig. 5, Reference numeral 4 is overlapping part, and we also can be referred to as trough 4, and this region only has electrode, does not need welding electronic component.As a preferred embodiment, trough 4 be shaped as square.
Can reach the bar shaped flexible PCB of random length with above-mentioned method for folding.
Fig. 3-Fig. 5 shows the method for folding strip circuit board, can be with reference to prior art for the method that corner is folding, folding at any local corner, also can fold in the position of trough 4, in the folding larger advantage in addition in the position of trough 4, the space of a whole page of the circuit board of folding rear adjacent edge belongs to the same face before folding; Can allow like this after electronic devices and components welding also in the same face, and in the time producing flexible PCB, wires design also can be simpler.Can be according to the requirement of concrete size, make the flexible PCB of coupling, meet that carry out corner in overlapping position folding.
