Description of the Invention The present invention relates to a circuit board detection method for detecting a circuit board circuit leakage, which can accurately detect the circuit board circuit deviation and the resulting problem. ^ The test method is used by the manufacturer to test the quality of the finished circuit board. It is mainly used to understand the details of circuit boards, especially the through holes of multilayer boards. The structure cannot be relied only on the appearance inspection: electrical test, so its structure needs to be further improved-/ ir · less sectioned: oSeCtining) microscopic inspection. As shown in the tenth figure, a schematic diagram of the finished product of the == circuit board (70) is revealed, and the middle part is a complex line of the early (71). As can be seen from the figure, the circuit board (70) ^ The edge of the circuit unit (71) is reserved with a board edge (701) with a suitable width, and the edge of the circuit unit (71) is also reserved with a board edge (711); of which: the circuit board (7 〇) The surrounding board edge (了 〇1) is used by the manufacturer to perform various actions such as clamping during the manufacturing process. As for the circuit unit (7 1) and the circuit board (70), a disconnectable form (Break- away panel), when used, it can be disconnected into an independent circuit board for packaging or other subsequent processes, and the board edge (7 1 1) reserved around the circuit unit (7 丄) is used for the aforementioned process. In addition, the “board edge sample” described in the previous disclosure is generally performed on the board edge (7Q1) around the circuit board (70), mainly because the board edge (7) reserved around the circuit board (70) 〇u has a large area, and the board edge (711) around the line unit (71) is unitized, so the area is very limited. The existing board edge sample must occupy a considerable amount of space. The self-interest method uses the line unit ( 71) board edge (711) for the aforementioned test. This paper size applies Chinese National Standard (CNS) A4 specification (210 X 297 mm) (Please read the precautions on the back before filling this page} Zhuangyi .. #_ Printed by the Consumers ’Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs A7 B7 V. Description of the invention (, there are μ ... description can be seen that there is a limitation in the implementation position of the existing" board edge sample ": this-the problem is actually necessary for the current implementation In addition to this problem, in addition to this problem, there are also accuracy issues: = As shown in Figure 11, the existing "board edge sample" is formed on the circuit board, where, = 2; = 1 (7〇1) Within the range, the shape of the road cutting is slowly pulled along; the line on the line area (72) ^: Zaoyuan (71) makes shapes at the same time It has the same circuit area. When testing the edge of the binding board, the micro-slicing method is used to saw the test line into the ground along the through hole, and then the saw is opened; : No, go to the center of the via hole, and then observe under the via hole with a microscope to see if it is indeed connected to the line to strengthen whether there is a missing connection.: As can be seen from the description of the above application method, first saw and then grind it. The method / knife is complicated, and its accuracy is still open to question. The immortal can only be judged by the-axis that is the same as the direction of the mine. Direction, so it is difficult to ensure the accuracy of the interpretation result. 1 stop [Who opened the mine: ri "board edge sample" Mostly the board edge sample is ordered in the diagonal position of the circuit board (70), but in fact the circuit The offset of the board (7〇) of the Intellectual Property Consumption Co., Ltd. and the offset at the diagonal are not necessarily the same. The report may be one = == 许 = 'the offset at the diagonal is outside the allowable range' … The method confirms that the line offset of that line unit (γ 丄) is still within the allowable range, and must, ', Obsolete, resulting in high costs.

Therefore, the present invention mainly aims at the process, I am a kind of circuit board detection method with a high degree of accuracy and simplicity and low cost. The proper position of the main circuit board adopted in order to achieve the aforementioned purpose is pure # 手 & A detection area to V, at least one common line in the detection area, is located on the bottom surface of the circuit board; most solder pads are located on the surface of the circuit board; alder needles, which penetrate the circuit board and are respectively located on the bottom of the pad, which constitute an electrical connection; : 〃 Then there are multiple windows formed on the common line, each window has an increasing inner #, and is aligned with the aforementioned probes. Under normal conditions, the common line on the bottom of the circuit board and the probe are open. Test; During the test, it is only necessary to test whether there is a short-circuit between the pads, thereby detecting whether the line in the circuit area is shifted, and then determining whether there is a leakage between the line and the pad. A soldering pad of the Keshu detection area is electrically connected to the common line of the bottom surface of the circuit board through a probe. Therefore, when testing, only the other soldering pads and the aforementioned soldering pads are short-circuited to determine whether they are missing. There are multiple circuit areas formed on the circuit board. Board edges are reserved around the circuit board, and board edges are also reserved around the circuit area. The aforementioned detection area can be located on the circuit board or the board reserved around the circuit area. On the edge. The probe in the aforementioned detection area is drilled on the circuit board first, and then perforated 5 (please read the precautions on the back before filling in this page).
