New Description: [New Technology Field] [0001] This paper is about a printed circuit board, especially a printed circuit board for transmitting high-speed signals. [Prior Art] [0002] In the prior art, the structure of the Mini SAS connector assembly used in the server is basically similar in both ends, so it cannot be confirmed whether one end of the Mini SAS connector combination is docked with its corresponding connector. For example, the upper and lower surfaces of the printed circuit board inside the Mini SAS connector have a plurality of conductive sheets, and have the same position and structure corresponding to the conductive sheets on the upper and lower surfaces of the printed circuit board inside the other Mini SAS connector. As such, the ends of the Mini SAS connector assembly are indistinguishable from each other and are prone to mismatch with the docking connector. [0003] Therefore, there is a need for an improved printed circuit board to compensate for the above-mentioned drawbacks of the prior art. [New Content] [0004] The main purpose of this creation is to provide a printed circuit board with a foolproof effect. [0005] The purpose of the present invention is achieved by the following technical solution: a printed circuit board having a front end edge, a plurality of conductive sheets formed on the upper and lower surfaces of the front end edge of the printed circuit board, and one of the conductive sheets The width is wider than other conductive sheets. [0006] Compared with the prior art, the present invention has the following effects: the width of one conductive sheet on one surface of the mating end of the printed circuit board is wider than that of other conductive sheets, and the form number A0101 is 3/8 of M425481. Printed circuit boards provide a foolproof effect unlike other printed circuit boards. [Embodiment] [0007] Referring to the first to second figures, the present printed circuit board 1 has a front end edge 11 and a rear end edge 12. The front end edge 11 of the printed circuit board 1 is its mating end for interfacing with the mating connector. The rear end edge 12 of the printed circuit board 1 can be electrically connected to a plurality of cables (not shown). A plurality of first conductive sheets U1 are formed on the upper and lower surfaces of the front end edge 11, and a plurality of second conductive sheets 121 are formed on the upper and lower surfaces of the rear end edge 12. The width of one of the plurality of first conductive sheets hi is wider than the width of the other first conductive sheets 111, and the width of the first conductive sheets 111' is larger than the width of the other two first conductive sheets 111. with. The first conductive sheet 111' may be formed on the upper surface or the lower surface of the front end edge 11 of the printed circuit board 1. [Wake] Printed circuit board 1 can be applied to the Mini SAS connector combination for server or computer internal connection. This Mini SAS connector combination includes two Mini SAS connectors with the same structure and two connectors. Cable. The printed circuit board 1 connects adjacent ones of the first conductive sheets m therein to form a wider one of the first conductive sheets lu, as compared with the prior art. When such a printed circuit board 1 is mounted on one of the two Mini SAS connectors, it can be clearly distinguished from the other existing printed circuit board when viewed from the mating end, providing a foolproof effect in use. On the other hand, the printed circuit board 1 can be designed in blue, so that there is a clear distinction between the current printed circuit board and the green printed circuit board. [0010] It should be noted that 'because the width of one conductive sheet on one surface of the mating end of the printed circuit board 1 is wider than the width of other conductive sheets, the blue printed circuit designator A0101 page 4 / 8 pages M425481 The board 1 is significantly different from the conventional green printed circuit board. Due to the above two factors, the above printed circuit board 1 is different from other printed circuit boards to provide a double foolproof effect. [0011] In summary, the creation complies with the new patent requirements, and the patent application is filed according to law. However, the above description is only a preferred embodiment of the present invention, and the scope of the present invention is not limited to the above embodiments, and those who are familiar with the skill of the present invention are equivalent to the equivalent modifications or changes made by the spirit of the present creation. It should be covered by the following patent application. BRIEF DESCRIPTION OF THE DRAWINGS [0012] The first figure is a top view of the present printed circuit board.
