A method and system for testing modem module on embedded pcba

Abstract

The invention provides a method and system for testing a Modem module on an embedded PCBA (Printed Circuit Board Assembly). The quick test method comprises the following steps: scanning a pluggable memory in a memory interface of the PCBA; loading a test code pre-stored in the pluggable memory and testing the Modem module; driving prompting equipment on the PCBA to send normal prompting information if the result of the test is normal, otherwise, driving the prompting equipment on the PCBA to send abnormal prompting information. By utilizing the embedded PCBA to load the test code of the pluggable memory to perform a test to the Modem module, the quality of an SMT (Surface-mount Technology) of the Modem module can be quickly tested, and the result of the test can be visually observed, as a result, test efficiency is greatly improved, and a hardware guarantee is provided for the following normal working of the whole machine.

Description

technical field [0001] The invention relates to a method and system for testing a Modem 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 thin clients, display screens, etc., and common embedded devices in life include MP3, 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 base, production e...

AI Technical Summary

Problems solved by technology

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 the position of the components on different batches of PCBA changes, once the test points on the PCB are blocked and need to be changed, the needle bed needs to be modified accordingly, which is very cumbersome

[0009] To sum up, there are problems such as high test cost and cumbersome test process in the existing technology for testing the Modem module on the PCBA, which has limited the production efficiency of electronic communication products and cannot meet the needs of technological development.
