Description
technical field [0001] The invention relates to the technical field of electronic circuit board testing equipment, in particular to a PCBA function testing system. Background technique [0002] With the rapid development of electronic technology, the PCBA (circuit board mounted) used in various electronic devices is becoming more and more sophisticated. The performance of PCBA directly determines the quality of the entire product to a large extent. Therefore, in the PCBA production process, it is required to add various test equipment and test tools at the end of the production process to ensure that all the installed circuit boards in the factory conform to the various specifications and parameters at the time of design. [0003] PCBA testing includes multiple indicators such as circuit testing, voltage, current, resistance, and power consumption, and requires the use of a variety of testing instruments. The current testing methods have many problems such as low testing ef...
