The PCBA test in this comparison document uses a testing platform including a bed of needles, and there are test needles corresponding to the PCBA test points on the testing platform of the needle bed. When testing the PCBA, it is necessary to reserve a test during PCB design. At the same time, it is necessary to make the needle bed, which greatly increases the time from research and development to the testing process, and also increases the testing cost of the enterprise.
At the same time, when...

Abstract

The invention provides a method and system for testing a communication module on an embedded printed circuit board assembly (PCBA). The fast testing method includes the following steps: scanning a pluggable storage in a storage interface on the PCBA; loading testing codes pre-stored in the pluggable storage, and testing the communication module; if the testing result is normal, driving a prompting device on the PCBA to send normal prompting information, and if the testing result is abnormal, driving the prompting device on the PCBA to send abnormal prompting information. By using the embedded PCBA to load the testing codes of the pluggable storage to conduct communication module testing, quality of the surface mount technology (SMT) of the communication module can be tested fast, the testing result can be observed directly, testing efficiency is greatly improved, and hardware guarantee is provided for follow-up normal work of a whole machine.

Description

technical field [0001] The invention relates to a method and system for testing a communication module on an embedded PCBA. Background technique [0002] PCBA: It is the abbreviation of Printed Circuit Board + Assembly in English, that is, the empty PCB board, after SMT (surface mount technology) upper part, and then through the whole process of DIP plug-in. The PCBA in the present invention is a circuit board that has not been fully assembled after patching. [0003] Embedded devices are increasingly entering people's lives. In industry, such as industrial computers, touch screens, etc., in business, such as client computers, display screens, etc., and common embedded devices in life include MP3 and MP4. Wearable electronic devices, set-top boxes, mobile phones, tablets, etc. As far as tablet is concerned, according to current industry development trends and analysis, the shipment of tablet PCs in 2013 is close to 200 million units. In the context of such a large-scale b...
