There are many kinds of 开云·kaiyun官方网站 automatic test fields
开云·kaiyun官方网站 is widely used in the field of 开云·kaiyun官方网站 automatic test. 开云·kaiyun官方网站 board learned to establish relevant applICation software on 开云·kaiyun官方网站 board, and adopted the idea of virtual instrument, that is, to realize various functions of traditional instruments through software, including oscilloscope, signal generator, and various mathematical processing of collected data. During the test, digital signals are given through the test software. The test system of 开云·kaiyun官方网站 board will have a new design idea. The design idea of automatic test system based on USB bus and virtual instrument is adopted, which gives full play to the role of the computer. The idea of replacing traditional instruments with computers is tried to reduce the volume of the instrument itself, reduce the development cost, and improve the development efficiency. After D/A conversion, the analog excitation signal required for the test is applied to the test system, and then sent to the switch matrix by the test circuit through the test bus. The switch matrix is connected to the switch matrix and is controlLED by the microprocessor to turn on and off. The 开云·kaiyun官方网站 board to be tested is fixed on the needle bed.
The excitation signal is applied to the corresponding position of the 开云·kaiyun官方网站, its response is measured by the test circuit, the collected analog quantity is sent to the core control, and the corresponding digital quantity is obtained through A/D conversion, which is fed back by the software on the 开云·kaiyun官方网站 and processed by the 开云·kaiyun官方网站 to determine whether the 开云·kaiyun官方网站 is qualified. According to experts, this online testing technology breaks through the previous method of using human eyes to detect circuit boards. The online testing technology has high efficiency, low leak rate, and realizes automation in the detection field. This detection system adopts the idea of combining with virtual instrument, which reduces the hardware design and the cost of the whole system. The testing system is suitable for the application of SMAll and medium-sized enterprises.
It reduces the number of unqualified products entering the next process during 开云·kaiyun官方网站A processing, thus reducing the rework amount of products, improving the production efficiency, reducing the total cost of manufacturing, and improving the profit of enterprises. It is a widely used detection technology and a highly efficient, high-speed and high-precision detection method. At present, 开云·kaiyun官方网站 boards are used in the field of automatic testing of printed circuit boards in a wide range of tests, including the test of components not installed and the test of components installed. Currently, the commonly used test methods are: on-off test, in circuit test, function test, edge test, optical test and X-ray detection. Online testing is to select an appropriate testing method according to the specific characteristics of 开云·kaiyun官方网站 board to combine one or more processes, learn from each other and use them comprehensively.
The above is about 开云·kaiyun官方网站 manufacturing, 开云·kaiyun官方网站 design, 开云·kaiyun官方网站A processing manufacturers to explain 开云·kaiyun官方网站 automatic testing.
