The specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
PCB composite plate of the present invention is at least the pcb board of 2 layers, and preferred PCB composite plate is the pcb board of 3 to 10 layers.In the PCB composite plate of 3 to 10 layers, every layer of pcb board all comprises that an insulated substrate and is printed on the conductive pattern layer on insulated substrate.What on a surface of insulated substrate, print conductive pattern layer is one side pcb board piece, what on two surfaces of insulated substrate, be printed with respectively conductive pattern layer is double-sided PCB board piece, the PCB composite plate of 3 to 10 layers can only consist of one side pcb board piece, also can only by double-sided PCB board piece, be formed, can also be combined and formed by one side pcb board piece and double-sided PCB board piece, concrete formation be determined according to specific needs.Between two adjacent pcb board pieces, an insulation adhesive sheet is set; insulation adhesive sheet is adhesive material; with insulation adhesive sheet, each pcb board piece is bonded to an integral body; thereby can make a whole PCB composite plate of 3 to 10 layers; can more effectively reduce the overall volume of PCB composite plate, insulation adhesive sheet can also play the effect of protection conductive pattern layer.
For example: 3 layers of PCB composite plate can be comprised of a double-sided PCB board piece and an one side pcb board piece; 3 layers of PCB composite plate also can be by three one side pcb board pieces with forming.
4 layers of PCB composite plate can be comprised of two double-sided PCB board pieces, or are comprised of two one side pcb board pieces and a double-sided PCB board piece, or are comprised of four one side pcb board pieces.
8 layers of PCB composite plate can be comprised of four double-sided PCB boards, or formed by two one side pcb board pieces and three double-sided PCB board pieces, or formed by four one side pcb board pieces and two double-sided PCB board pieces, or formed by six one side pcb board pieces and a double-sided PCB board piece, or formed by eight one side pcb board pieces.
Generally, to there being independently pcb board piece of some layers, respectively each insulation adhesive sheet is arranged between adjacent layer pcb board piece, by each layer independently pcb board piece be bonded to a whole PCB composite plate.

As shown in Figure 1, each layer of pcb board shape is identical, and each layer of pcb board is superimposed with each other along identical direction position centered by same point, and each pcb board size reduces gradually, superimposed to reach each layer of pcb board energy part.For example: superimposed with pcb board 101, pcb board 102 and the mutual part of pcb board 103 that pcb board 101 is same center position along same direction and the central point of pcb board 101 of take, when being superimposed with each other, pcb board size reduces gradually,, pcb board 102 is identical with pcb board 101 shapes, and, along same direction with same point center position, be superimposed with each other, pcb board 102 is less No. one than pcb board 101, at two pcb boards when superimposed, pcb board layer 101 part are superimposed, and each LED light emitting diode is arranged on the place that is not superimposed of pcb board layer 101.And for example pcb board 103 is identical with pcb board 102 shapes, and, along same direction and same position, be superimposed with each other, pcb board 103 is less No. one than pcb board 102, at two pcb boards, when superimposed, pcb board layer 102 part are superimposed, and each LED light emitting diode is arranged on the place that is not superimposed of pcb board layer 102; So analogize.Each layer of pcb board of PCB composite plate arranges at least one LED light emitting diode.As: LED light emitting diode 106 is installed and is arranged in pcb board layer 101, LED light emitting diode 105 is installed and is arranged in pcb board layer 102, LED light emitting diode 104 is installed and is arranged in pcb board layer 103, and, each LED light emitting diode of installing on each layer of pcb board is installed in the same direction, that is, LED light emitting diode 104, LED light emitting diode 105 are identical with LED light emitting diode 106 exiting surface directions.
On the conductive pattern layer of each pcb board layer, all install or be printed with a large amount of electronic devices and components and electronic circuit, for the LED light emitting diode that is arranged on each layer is normally worked as required.As: power line is set, to guarantee the power supply source of LED lumination of light emitting diode, resistance is and for example set, excessive to prevent the electric current of power supply circuits, or prevent LED light emitting diode to burn out.In order to make LED specious, and the dot spacing of minimizing LED light emitting diode, at less area, more LED light emitting diode is installed, on pcb board, install or the electronic devices and components of printing and the superimposed place that electronic circuit is all arranged on each pcb board layer.
The identical pcb board piece of each shape that forms PCB composite plate, its shape is different according to the occasion of application, or be triangle or for square or for circular or for star or for polygon or be that other are irregularly shaped.For example, the PCB composite plate finally forming can be hollow, linear, bar shaped, annular, chain, U word, water chestnut, semicircle, circle, ellipse, cylinder, trapezoidal, square, net form, prismatic, triangle, quadrangle, regular polygon, star, tree-like, regular shape combination, irregularly shaped combination, various customized graphicses etc.Customized graphics is as Santa Claus, snowman etc., and the present invention does not impose any restrictions this.
According to the occasion needs of application, each pcb board piece that forms PCB composite plate can be flexible PCB plate, can be also rigidity pcb board piece, or is both combination.Rigidity pcb board piece has certain mechanical strength, and the parts of dressing up with it have certain bending resistance, in use in flattened state.Flexible PCB plate is to take soft laminated plastics or other soft insulating materials to make as base material, and its made parts can be crooked and flexible, in use can be according to installation requirement by its bending moulding.And had under certain mechanical strength by the PCB composite plate of rigidity pcb board piece and the combination of flexible PCB plate, can carry out bending moulding to a certain degree.
More particularly, a certain pcb board piece can be the combination of flexible PCB plate and rigidity pcb board piece, that is, its part is flexible PCB plate, and part is rigidity pcb board piece; For example, the rigidity pcb board interblock row of the flexible PCB plate of pcb board piece bar shaped and bar shaped form, i.e. the flexible PCB plate A of a row bar shaped, and side is the rigidity pcb board piece B of a row bar shaped, the another side of rigidity pcb board piece B is the flexible PCB plate C of a row bar shaped, is arranged in order.
As shown in Figure 2, identical shaped each layer pcb board can also be along same direction, superimposed with the mutual part of different center position, and, each layer of pcb board measure-alike.In Fig. 2, pcb board layer 206, pcb board layer 204 and pcb board layer 202 are the identical and measure-alike pcb board layers of three shapes, three pcb board layers are along same level direction, centered by diverse location, put mutual part superimposed, and, on each pcb board layer, at least form a space, each pcb board layer is at least installed a LED light emitting diode, and each LED light emitting diode is installed and is arranged on each space.
Each layer of pcb board that shape is identical, along same direction, when superimposed with the mutual part of different center position, the size of each layer of pcb board can be also difference, as long as reach can each pcb board part superimposed.In Fig. 2, pcb board layer 206, pcb board layer 208 and the outer pcb board layer that three shapes are identical and size is not identical of pcb board layer 210, pcb board layer 206, pcb board layer 208 and pcb board layer 210 are when part is superimposed mutually, on each pcb board layer, at least form a space, each pcb board layer is at least installed a LED light emitting diode, and each LED light emitting diode is installed and is arranged on each space.
At least one LED light emitting diode of arranging is installed on each pcb board layer, and each LED light emitting diode not only can be installed and arrange along identical exiting surface direction, can also install and arrange along different exiting surface directions.In Fig. 2, along level direction up, LED light emitting diode 201 is installed and is arranged on pcb board layer 202, and LED light emitting diode 203 is installed and is arranged on pcb board layer 204; Along level direction down, LED light emitting diode 209 is installed and is arranged in pcb board layer 210, and LED light emitting diode 211 is installed and is arranged in pcb board layer 208; Along level to right, LED light emitting diode 205 is arranged in pcb board layer 206, and LED light emitting diode 207 is installed and is arranged in pcb board layer 208.So, each LED light emitting diode can be installed and arrange along 360 degree different directions, and the light of all directions is even, and brightness is large, and visual angle is wider, and decorative effect is relatively good.Each electronic devices and components and electronic circuit are arranged on each layer of superimposed place of pcb board, for LED light emitting diode is normally worked as required.
