Description of the Invention: [Technical Field] The present invention relates to a printed circuit board test apparatus, particularly a printed circuit board test I which is operated by a computer controlled needle bed for testing. [Prior Art] Know: 'The test of electronic products has its history of sorrow. In the late stage of the β 〇, it was the first automated test method, so it was widely praised but it was woven with the 7G era. The technical skills test seems to be destined to be eliminated. However, today's trend has changed, and online testing is on the issue of “detection methods”. According to the analysis of the National Electronics Manufacturing Group II (face), with the change of circuit board manufacturing technology, the number of nodes available for detection on the circuit board will approach zero, and if the measurement cannot be performed, the online test is almost useless. Ground. j slave electronic products to measure miscellaneous, Wei Weizheng should be widely used in the process of the line; even in the middle of the process test. However, the tenderness, and the previous merits, the high component density and high test speed of the 偻^h king, the functional test by hand is not enough. Replace the test points on the board with the needle bed for function measurement! 258587 Test 0 Refer to the figure - diagram of the typical test needle bed structure. As shown in the figure, the test needle bed 100 structure includes a jig 12, a control circuit board 140 and a computer device 160. Among them, the household °^'12〇 is embedded with a plurality of rides up and down, and the test points on the circuit board 200 are tested (please refer to the first figure a). The computer device (10) is read through the control circuit board 14 and the (10) test point position to be tested. The control circuit board 14 transmits the test result back to the computer device, and also provides the power supply required for the test circuit board 2 to perform the test. Generally, the test obtained through the test needle bed structure is data. According to the information, this information can only represent the short/open circuit or bad situation of the line. As the functions of electronic products become more complex, the testing of circuit boards can sometimes be judged clearly only by data. Therefore, sometimes it is necessary to input the circuit board to be tested with a false signal 'for example, test image', and then detect the output signal of the circuit board to be tested to determine whether the function of the circuit board is normal. However, this test method has to cost several times the time cost and device cost. At the same time, the functions it can test are limited by the design of the false signal, and often cannot be completed. Baxi Yu is how to improve the function of the existing test needle bed structure to meet the needs of today's multi-function circuit boards, so that the time required for the secret board _ is a sub-product functional test towel, the most human OBJECT OF THE INVENTION [1] The main object of the present invention is to provide a printed circuit board test apparatus that can be used for functional testing to meet the needs of today's multifunctional circuit boards. The multifunctional printed circuit board testing device provided by the invention comprises a fixture, a control circuit, a computer device and a diagnostic code. The fixture includes a plurality of probes that can be moved up and down, and are respectively aligned with test buttons on a circuit board to be tested. The control circuit is electrically connected to the fixture to control the movement of the probe. The computer device is electrically connected to the control circuit through the cable, and the input control signal controls the movement of the probe, and a test signal is input through the probe to the circuit board to be tested. The diagnostic code is pre-written in the memory in the board to be tested before the function test of the board to be tested. When the function test is performed, the circuit board to be tested is based on the above test signal to execute the diagnostic code ▲ in the memory, and the execution result is infused into the computer money, and the function of the shutdown circuit board is normal. According to the present invention, the method for functional testing of the multi-wei apparatus circuit board includes the following steps: • writing a diagnostic code to the memory of the circuit board to be tested; The needle makes contact with the test point on the printed circuit board; the test line is connected to a test line, and the test board of the road board is used to test the test result of the functional description characteristic; the result of the probe is ~, 丨^ To determine whether the function of the board to be tested is normal. The advantages and spirit of the attached ^ 彳 = can be understood by the following detailed description of the invention and the drawings. [Embodiment] 凊 Refer to the second figure of the +# road board test device - a block diagram of the multi-function printing electrical example provided by the actual solution. This multi-function printing! 258587 circuit board measurement „sample system includes a fixture 320, a control circuit and a computer device 360. Among them, the fixture 320 includes a plurality of probes that can move up and down 'aligned separately - to be tested The test button on the circuit board 2. The control circuit is electrically connected to the control tool. The electric service system is electrically connected to the control circuit 340 through the cable, and controls the movement of the probe through the input control signal, and transmits the probe through the probe. Input a test signal to the board to be tested 2〇〇. Generally, the text is limited to the way of the probe input. This test telecommunications helmet provides relatively complicated test instructions, so the input is only by the probe. It is difficult to control the circuit board 200 to be tested. Therefore, a diagnostic code is written into the memory of the circuit board 2 to be tested before the test starts. When performing the function domain measurement, the processing center 22 of the circuit board to be tested is based on the test signal from the probe to access the column code of the recording body 2 (4), and the execution result is output to the brain device. For the judgement of the board Whether it can be normal. Explain the control circuit board of the scanner to be tested. Traditionally, it is known that the image is output to the computer, so that the function of the control board is normal. In the case of a printed circuit board test device, if the sputum is stored in the memory as a diagnostic code, and the probe is notified to the control panel to transmit the image charm device for interpretation, the purpose of the function test can be achieved. The simplification of the test signal from the probe is the address and read command of the image slot in the memory. The test signal is passed to the circuit board and the diagnostic code is transmitted to the preset Around the age of the site 1258587
