Abstract

The invention discloses a PCBA function detection system. The system comprises an upper probe board, a lower probe board, a test circuit board, a substrate used for power supply and signal bridging, arelay board and a platform circuit board, wherein the upper probe board and the lower probe board are respectively provided with a plurality of probes used for contacting products, and the platform circuit board comprises a frequency test unit, an open circuit test unit, a short circuit test unit and a load test unit; the upper probe board and the lower probe board are in butt joint with a product of a client and form an analog signal through the test circuit board, signal switching is carried out by adjusting the relay board, the frequency is measured through the frequency test unit, the open circuit and short circuit problems are detected through the open circuit test unit and the short circuit test unit, and load state data are extracted through the load test unit. Multiple tests can be carried out, detection can be rapidly carried out, the automation degree is high, a virtual PCBA is formed by simulating products, PCBA problem points can be rapidly positioned, and the efficiency is improved. The invention also discloses a PCBA function detection method.

Description

technical field [0001] The invention relates to the field of circuit boards, in particular to a PCBA function detection system and method. Background technique [0002] With the increasing update of technology, the integration of electronic products is getting higher and higher, the functionality is becoming more and more powerful, and the replacement is becoming more frequent. Therefore, the FCT testing industry has also become the mainstream industry in the testing industry. Tests of voltage, current, frequency, open and short circuits, etc. have also become the priority test requirements of some companies' products, so that the designed PCBA can be quickly tested and verified for specific functions in a timely manner. Therefore, a well-designed FCT test module and the quality of the module have become the focus of various companies. [0003] At present, the test equipment produced by the FCT industry is composed of many non-functional PCBAs that are used together to com...
