Test method and system thereof. [Prior Art] Printed circuit board (PCB) is almost out of the current digital and non-digital electrical devices. In addition to the use of various electronic components, the main functions must be able to provide Each of the first $7 _ pieces of _ mutual current connection to achieve the desired function; with ^ in the electronic products, equipment functions are more and more complex, the number of electronic components on the printed circuit board is also more and more, Relatively speaking, when the wiring on the printed circuit board is dense, the product inspection of the printed circuit board becomes a critical technology and process due to the difficulty in detecting the product. Μ Most of the inspection methods for pCB are based on the test of the online test machine. The principle is that each circuit node on the pcB has a space for the job site, which is used for the line contact of the probe disk (10) of the Ια and is connected with the test system, and is dependent on each component=characteristic requirement' The sequence is tested by the associated test points, flow or voltage to check that the quality of each part is good. ;,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, The extent of space required for ICT test points.

In the case where the printed circuit board cannot pass the test, the printed circuit board that cannot be tested is determined to be defective, and the serial number of the untested printed circuit board is printed and the printed circuit board is subjected to an undetected item. The detection action determines that the printed circuit board is a good or bad product measurement process when the initial test is performed. (4) Effect: Compared with the above-mentioned existing known technology, the present invention has the following work: 1. The present invention is to produce money. The printed circuit board is dispersed to some of the different detection programs of the test item to perform the preliminary test. The average time for each of the two printed pen boards to be detected is significantly shorter than the time for all the test items to be completed by a single printed circuit board. It can effectively improve the on-line detection speed of printed circuit boards and increase the productivity of printed circuit boards. 2. The invention can be based on the production speed of the actual production line, and is suitable for the identification of the main detection items and the secondary inspection items, so that the actual detection speed is consistent with the production flow time and meets the requirements of the line balance. 3. The method of the present invention for dispersing the detection process is particularly suitable for a long time-consuming inspection process such as an automatic optical inspection device (ΑΟί) applied to a printed circuit board assembly line. 4 • At least three projects on the printed circuit board assembly line are suitable for inspection work with A 01 equipment, which is post-printing inspection (SPI), post-installation inspection (PMI, Post Mounter Inspection) and reflow Post Ref low Inspection.

Because of the high-reproducibility of the quality of the products produced by the automated production line, the quality of the products produced by the sequential production of the two production lines is quite relevant and consistent, so in the case of printing If the circuit board cannot pass the preliminary test, it cannot be judged as a defective product by preliminary detection of the printed circuit board; as for the printed circuit board that cannot pass the preliminary detection of a serial number in front of the printed circuit board and has passed the preliminary inspection: Then, the detection operation of the undetected item must be performed to further determine that the printed circuit board that has passed the preliminary detection is a good bite defective product, thereby greatly improving the speed of the printed circuit 9 200842346 on the board line and ensuring the dispersion detection process. Reliability of testing. Silk: t::: Widely invented to perform the inspection of printed circuit boards and a decision unit; among them: ten serial numbers are arranged early, and the west recognizes t, and the flat system is all on the printed circuit board. The test items are divided into blowing, test items and main test items, and the main test items or 70 pieces are either absolutely _ _ _ _ _ _::, and it is necessary to strengthen the inspection of the inspection work 2 while the inspection is required The test item is divided into two parts, and the two divided parts are combined with the main detection items to become two detections of A and B. The two detection programs of A and B are respectively used for detecting items. Target - part of the secondary inspection project. The order of the m-order, the flat-unit unit is to be sequentially entered into the serial number of the printed circuit board, and the serial type and odd-numbered printed circuit boards are respectively sent to the A 4 detection program. Separately, a printed circuit board is sequentially tested. 'This A, B detection program can be automatically switched during the inspection to facilitate interval inspection on adjacent printed circuit boards; as for the determination unit is used to Initially passing the detected printed circuit board to the temporary storage area 'and determining that the printed circuit board in front of the printed circuit board has passed the preliminary inspection of the printed circuit board as a good one', and in the case that the printed circuit board cannot pass the preliminary detection, After the complete inspection of the printed circuit board is not possible, it is determined that it is a defective product, and it is determined that the detection operation of the undetected item cannot be performed by initially detecting a printed circuit board whose serial number has passed the preliminary detection on the printed circuit board. The printed circuit board that has been previously tested by the initial step 200842346 is a good or defective product. As shown in the second diagram of the printed circuit board detection flow chart of the present invention, when the printed circuit board detection system of the present invention is in operation, the serial number of the printed circuit board of the system is sequentially sequenced by the serial number sequence, and the serial number is adopted. The serial number even and the odd number of printed circuit boards are respectively subjected to the A and B detection programs to make two printings, and the circuit board performs preliminary inspection of the main items and the secondary items in the actual detection process, and the determining unit firstly The preliminary printed circuit board is sent to the temporary storage area, and in the case where the two serial numbers are successively detected, the front board is judged to pass the preliminary detection circuit board (that is, the front-number has passed the preliminary detection). The board's 'step-by-step record' is printed as a good product: plate order;: as a basis for subsequent judgment comparison and statistics. Next, except for the case of "^田益遇Λ印(四) The board cannot pass the preliminary test. Outside the board 1 'and will not be able to pass the preliminary inspection printing _ = two = printed circuit board that has passed the preliminary inspection printed circuit (four) good quality has passed the preliminary inspection of the secondary Speculation: After the production of the printed circuit board is dispersed to the partial brush circuit board side, the dual test program performs the preliminary test 'the average time of each two prints, which is obviously higher than the line inspection degree of a single printed circuit, and the sigh is raised = the printed circuit is improved. It is used in the production capacity of the printed circuit city and the second-action u-board. It is especially suitable for the long-term inspection process of the automatic optical inspection equipment (A0I) and the 200842346; in the specific implementation, it can also produce the water according to the actual production. Based on the speed, the main inspection items and the secondary inspection items are identified appropriately, so that the actual inspection speed is consistent with the production flow time, and the pipeline balance and the maximum inspection coverage rate are met. The technical content and technical features of the present invention It is to be understood that the subject matter of the present invention may be modified and modified without departing from the spirit and scope of the invention. It should be included in all kinds of replacements and modifications of the present invention and is covered by the patent application scope of the town.
