Description of the Invention: [Technical Field] The present invention relates to a detection system and a detection board therefor, and in particular to a circuit board for detecting a bare board or a plug-in (p〇pulated) The guiding module used. [Prior Art] The general assembly circuit board production process mainly includes surface adhesion, wave soldering and inspection processes. The inspection process (Functi〇n Test Pr〇cess) includes In-Circuit Tester (ICT) Manufacture Defect Analyzer (MDA) and Functional Test (FT) are mainly used to detect whether the board is defective in the process, detecting parts and design functions. In this process, a large number of Manpower and time, so the industry wants to shorten the inspection time or simplify the inspection process to improve the efficiency of detection. Referring to Fig. 1, a motherboard 9 has a circuit board 91 and an electrical connector 92 for electrically connecting an electronic component (not shown). The electrical connector 92 has a valley to 90 and a plurality of conductive terminals 92A. For the convenience of the detection, a conductive module 93 is placed in the cavity 9 of the electrical connector 92. The conductive module 93 has a plurality of conductive holes 9 导1 connected to the conductive terminals 921. Therefore, the detecting personnel only need to use the detecting rod 81 of the detecting device 8 to detect the guiding hole 901 of the guiding module 93, and it can be known whether the motherboard 9 has an open/short circuit or component damage. Referring to FIG. 1, FIG. 2 and FIG. 3, the guiding module 93 for detecting has an upper surface 932 (as shown in FIG. 2) and a lower surface 931 (FIG. 3), and a lower surface 931 cloth 5 1328688 is provided with a plurality of metal contacts. 920, for the corresponding conductive terminal 921 of the conductive connector 92, the upper surface 932 is provided with a plurality of detection points 93 〇 for the detector? Detector 8 of § 8 - The conductive terminals 921 of the detecting electrical connector 92 are turned on or not. However, the currently used guiding module 93 has the following disadvantages: 1. As shown in FIG. 2, since each detecting point 93 of the upper surface 932 has the same appearance, it is difficult for the detecting personnel to quickly find the detecting point 93 that needs to be detected. 〇〇2. Some detection points for adjusting the signal, because they are hidden in many detection points 930, it is very troublesome to rely on the experience of the inspectors or to check the checklists to find the detection points for the adjustment signals. 3. Since the inspection point 930 is also coated with a metal coating on the surface of the contact fastening device (generally an iron cover), it is easy to expose the bare copper to form a short circuit when the fastening device applies pressure. SUMMARY OF THE INVENTION In view of the fact that the function of an electronic component has a certain signal type, for example, it can be classified into a voltage, an address, a material, and a control signal type according to the difference of the transmission signal. If each detection point can be marked with its category, It will help the inspectors quickly identify the detection points that need to be tested. Accordingly, it is an object of the present invention to provide a pilot module for a test circuit board that allows an inspector to quickly find a detection point. Another object of the present invention is to provide a pilot module for a test circuit board that allows an inspector to quickly find an access point. Therefore, the guiding module for the detecting circuit board of the present invention comprises a board body and a plurality of guiding portions extending through the board body, the board body has a first surface and a second surface, and each of the guiding portions a first contact and a second contact H are formed on the first surface 1 to form a contact: the first surface and the conductive path of the circuit board are electrically connected to: the conductive connection Each of the first contacts of the module can be distinguished from the appearance of the signal type by the appearance.

The electrical connector is tested. Referring to FIG. 4, when the detecting personnel detects, the guiding module is only placed in the housing 30 of the electrical connector 32, and then the probe of the detecting device 2 is used to contact the first contact 111 or the detecting point 1丨. 3 can be. Referring to FIG. 7, the guiding module for the detecting circuit board of the present invention is used in the second embodiment to test a circuit board of an empty board (not plugged in) by using a circuit test system 6 for internal circuit detection (In_circuit Tester). 31. The guiding module 1 used is the same as that of the first embodiment, and therefore its construction and principle will not be described again. The circuit test system 6 includes a control host 611, a display device 612, an input device 613, a detection circuit 621, and a detection needle bed (Bed Naf Nails) 622. Referring to FIG. 5 and FIG. 7 , the first surface 11 of the guiding module i is directed toward the detecting needle bed 622 having a plurality of elastic probes 623 , and each of the first contacts and/or the testing points 113 corresponds to each elastic probe.

Each detecting point can be <appears to the associated signal type, such as power, address, data or control. Any of the signal categories are marked with different shapes, characters, colors or lines, and the inspection or maintenance personnel can quickly find the detection points that need to be tested. 2. Set some detection points for adjusting signals to the key detection area. The inspection personnel can easily adjust to the detection points of the key detection areas without having to experience or look up the table. 3. Since the detection point of the general conduction module is also a metal coating on the surface of the contact fastening device (generally the iron cover), the detection points can be changed to the guide holes without metal coating on the surface layer, so when tightening When the device is pressurized, bare copper is not exposed to form a short circuit. 4. Since the maintenance personnel can quickly find out the inspection points that need to be tested, it can save a lot of time for the inspectors to measure each signal during testing or maintenance. The above is only the preferred embodiment of the present invention, and the scope of the present invention is not limited thereto, that is, the simple equivalent changes and modifications made by the present invention in accordance with the scope of the invention and the description of the invention. All remain within the scope of the invention patent. [Simple description of the map]
