- Generally speaking, a conventional circuit board for carrying and electrically connecting a plurality of electronic components is mainly constituted of a plurality of wiring layers and a plurality of insulating layers which are stacked alternately. The wiring layers are formed of copper foils via a lithography/etching process, and the insulating layers are disposed between the adjacent wiring layers respectively, so as to isolate the wiring layers. Furthermore, the stacked wiring layers are electrically connected to one another through conductive vias. Additionally, various electronic components, such as active components or passive components, are further arranged on the surface of the circuit board, so as to achieve the purpose of electrical signal propagation through the circuits inside the circuit board.
- In notebook computers, with different sizes (such as 14 inches, 15 inches, or 17 inches) of the displays of the notebook computers, the sizes of the mainboards arranged inside the mainframes of the notebook computers are also different. In the conventional art, manufacturers usually adopt different processes to meet different requirements on the sizes of the mainboards. However, the manufacturing cost is high if the mainboards with different sizes are manufactured through different processes.
- In addition to the aforementioned conventional art, another conventional art is further provided.
FIG. 1 is a schematic view of a conventional mainboard. Referring toFIG. 1 , theconventional mainboard 100 is applicable to a notebook computer having a 14-inch display. When theconventional mainboard 100 is applied in a notebook computer having a 15-inch display, a plurality ofconnectors 110 on themainboard 100 cannot meet the design of the internal space of the mainframe (not shown), so theconnectors 110 cannot be exposed outside the mainframe. Therefore, themainboard 100 must be electrically connected to amedium circuit board 10. - In particular, the
medium circuit board 10 has a plurality ofconnectors 12. Theconnectors 110 on themainboard 100 are electrically connected to theconnectors 12 of themedium circuit board 10 through aconnection cable 120. Theconnectors 12 are partially exposed outside the mainframe to connect peripheral equipments. However, themedium circuit board 10 and theconnection cable 120 causes an increase of the cost and occupies the internal space of the mainframes, and also more working hours must be spent in assembling themedium circuit board 10 and theconnection cable 120. - Accordingly, the present invention is directed to providing a circuit board which is applicable to notebook computers with different sizes.
- The circuit board provided by the present invention comprises a board body, at least one first connector, and at least one second connector. The board has an edge and at least one auxiliary scribed line. The auxiliary scribed line is substantially parallel to the edge. The first connector is disposed on the board body and adjacent to the edge. The second connector is disposed on the board body and adjacent to the auxiliary scribed line. The second connector is electrically connected to the first connector. The first connector and the second connector are located on the different sides of the auxiliary scribed line.
- In an embodiment of the present invention, the board body may have a connection circuit and the second connector is electrically connected to the first connector through the connection circuit. Furthermore, the connection circuit may have a plurality of connection wires, and the interval between every adjacent two of the connection wires may be larger than or equal to 1 mm.
- In an embodiment of the present invention, the board body may have at least one single wiring layer area. Two opposite borders of the single wiring layer area maintain a first interval and a second interval with the auxiliary scribed line respectively, such that the single wiring layer area covers the auxiliary scribed line. Furthermore, the first interval may be larger than or equal to 3 mm and less than or equal to 4 mm. Additionally, the second interval may be larger than or equal to 3 mm and less than or equal to 4 mm.
- In view of the above, because the circuit board provided by the present invention is manufactured through the same process and then cut so as to be applied in notebook computers with different sizes, compared with the conventional arts, the manufacturing cost of the circuit board provided by the present invention is lower and the manufacturing process is simpler. Since the circuit board provided by the present invention is cut to be disposed in the mainframes of the notebook computers with different sizes, compared with the conventional arts, the circuit board provided by the present invention is not required to be electrically connected to the medium circuit board. Accordingly, the circuit board provided by the present invention does not occupy more internal space of the mainframes, and the signal transmitted by the connectors of the circuit board provided by the present invention has a preferable quality.

Thefirst connectors 220 are disposed on one side of the auxiliary scribedline 214 near theedge 212 and thesecond connectors 230 are disposed on the other side of the auxiliary scribedline 214 near theedge 212. Furthermore, thethird connectors 240 are electrically connected to the second connectors 230 s respectively. Thesecond connectors 230 are disposed on one side of the auxiliary scribedline 214 away from theedge 212 and thethird connectors 240 are disposed on the other side of the auxiliary scribedline 214 away from theedge 212. - It should be noted that the
circuit board 200 of this embodiment is applicable to the notebook computers having 17-inch, 15-inch, or 14-inch displays. Thecircuit board 200 of this embodiment may be directly applied in the notebook computer with a 17-inch display. If thecircuit board 200 of this embodiment is applied in the notebook computer with a 15-inch display, thecircuit board 200 is cut with reference to the auxiliary scribedline 214 near theedge 212. In this way, if thecircuit board 200 in this embodiment is applied in the notebook computer with a 14-inch display, thecircuit board 200 is cut with reference to the auxiliary scribedline 214 away from theedge 212. Therefore, thecircuit board 200 in this embodiment may be applied in the notebook computers with different sizes. - In this embodiment, the
board body 210 may have a plurality offirst connection circuits 216 and a plurality of second connection circuits 218. Each of thefirst connection circuits 216 has a plurality offirst connection wires 216 a (twofirst connection wires 216 a schematically shown inFIG. 2 ), and each of the second connection circuits 218 has a plurality of second connection wires 218 a (two second connection wires 218 a schematically shown inFIG. 2 ). Each of thesecond connectors 230 is correspondingly electrically connected to one of thefirst connectors 220 through thefirst connection wires 216 a of one of thefirst connection circuits 216. Each of thethird connectors 240 is correspondingly electrically connected to one of thesecond connectors 230 through the second connection wires 218 a of one of the second connection circuits 218. - It should be noted that the
first connectors 220, thesecond connectors 230, and thethird connectors 240 in this embodiment may be suitable for connecting peripheral equipments, such as a mouse, a display, a keyboard, a printer, or a plotter. It should be emphasized that as for the relative positions as shown inFIG. 2 , if thefirst connectors 220 are suitable for connecting the mouse, the keyboard, and the printer from left to right thesecond connectors 230 and thethird connectors 240 are also suitable for connecting the mouse, the keyboard, and the printer from left to right. In other words, one of thefirst connectors 220, one of thesecond connectors 230, and one of thethird connectors 240 which are correspondingly electrically connected are suitable for being connected to the same peripheral equipment. - In this embodiment, the interval d1 between every adjacent two of the
first connection wires 216 a may be larger than or equal to 1 mm, and the interval d2 between every adjacent two of the second connection wires 218 a may be larger than or equal to 1 mm. The intervals d1 and d2 prevent the short of the adjacentfirst connection wires 216 a or the adjacent second connection wires 218 a of thecircuit board 200 after being cut. Referring toFIGS. 2 and 3 ,FIG. 3 is a schematic view of the circuit board ofFIG. 2 after being cut. For example, after thecircuit board 200 is cut with reference to the auxiliary scribedline 214 near theedge 212, thefirst connection wires 216 a are also cut and anew edge 212′ of thecut circuit board 200′ is substantially the auxiliary scribedline 214 of theoriginal circuit board 200 near theedge 212. Since the interval d1 between every adjacent two of thefirst connection wires 216 a is larger than or equal to 1 mm, the adjacent cutfirst connection wires 216 a′ at thenew edge 212′ of thecut circuit board 200′ may not contact one another to cause the short circuit. - Referring to
FIG. 2 again, theboard body 210 of this embodiment may have a first singlewiring layer area 211 and a second single wiring layer area 213. Twoopposite borders 211 a and 211 b of the first singlewiring layer area 211 maintain two intervals d3, d4 with the auxiliary scribedline 214 near theedge 212 respectively, such that the first singlewiring layer area 211 covers the auxiliary scribedline 214 near theedge 212. Twoopposite borders 213 a and 213 b of the second single wiring layer area 213 maintain two intervals d5, d6 with the auxiliary scribedline 214 away from theedge 212 respectively, such that the second single wiring layer area 213 covers the auxiliary scribedline 214 away from theedge 212. Furthermore, the intervals d3, d4, d5, d6 may be larger than or equal to 3 mm and less than or equal to 4 mm. - In the range covered by the first single
wiring layer area 211, the wiring is layer where thefirst connection circuits 216 are located is a single wiring layer of theboard body 210. Thefirst connection circuits 216 may be disposed on the surface of or inside theboard body 210 according to the requirements of the designers. In this way, in the range covered by the second single wiring layer area 213, the wiring layer where the second connection circuits 218 are located is a single wiring layer of theboard body 210. The second connection circuits 218 may be disposed on the surface of or inside theboard body 210 according to the requirements of the designers. - Referring to
FIGS. 2 and 3 , it should be noted that after thecircuit board 200 is cut with reference to the auxiliary scribedline 214 near theedge 212, since the wiring layer where thefirst connection circuits 216 are located is a single wiring layer, thecut connection wires 216 a′ at thenew edge 212′ of thecut circuit board 200′ may not contact other wiring layers to cause the short circuit. - In view of the above, the circuit board provided by the present invention has at least the following advantages.
