PCBA (printed circuit board assembly) detecting device and detecting method

Abstract

The invention discloses a PCBA (printed circuit board assembly) detecting device and a detecting method. The detecting device comprises a code scanning gun, a clamp, a displayer, a control module, a server, a core control system, a digital multimeter module, a simulative battery module, a programmable direct current power module and a direct current electronic load, and others; the core control system comprises a power processing unit, a control unit, a sampling unit, a communication unit, a dry contact unit, a charging machine simulative unit, a small load unit, an insulation simulating unit, a switch matrix unit, a NTC detecting unit, a clock detecting unit and a digital input/output unit. The PCBA detecting device and the detecting method apply a brand-new software framework to realize the complete automation of the function testing process, and the resource is fully used; meanwhile, data is accessed to a MES system and can be checked at any time and any place in the era of unblocked network; moreover, the whole detecting device is convenient to operate and has the advantages of greatly improving the testing efficiency and reducing the testing cost of the factory PCBA.

Description

technical field [0001] The invention relates to the field of PCBA (Printed Circuit Board Assembly: printed circuit board assembly) function testing, in particular to a PCBA detection device and detection method. Background technique [0002] At present, the electronics industry is developing rapidly, and consumers are paying more and more attention to product quality. Therefore, various electronics companies pay more attention to product testing to ensure high-quality products; while investing a lot of manpower and material resources in the research and development stage to test products, the products The testing in the factory is also getting more and more attention, especially automotive electronic products, before the PCBA leaves the factory, it needs to go through a strict functional test to judge whether the PCBA can meet the predetermined functional requirements to ensure its quality, and at the same time keep the factory test records Easy to trace. [0003] Due to th...

AI Technical Summary

Problems solved by technology

[0003] Due to the large number of PCBA functional test items of the vehicle battery management system, the test process is complicated, and the traceability is required

However, at present, the functional testing of the vehicle battery management system requires more manual participation in the functional testing process. Controlling the equipment based on experience and intuition cannot guarantee the integrity and accuracy of the functional testing; the same test platform does not satisfy all battery management requirements. System testing and poor scalability lead to high development costs and waste of resources; test data is generally stored locally on the server or saved in documents, which is not conducive to abnormal data tracking and brings new problems to production management and maintenance
