Method and system for testing GPS (global position system) module on embedded PCBA (printed circuit board assembly)

Abstract

The invention provides a method and a system for testing a GPS (global position system) module on an embedded PCBA (printed circuit board assembly). The quick testing method includes the following steps: scanning a pluggable storage in a storage port on the PCBA, loading a pre-stored testing code in the pluggable storage, testing the GPS module, if a testing result is normal, driving a prompt device on the PCBA to send out normal prompt information, and if the testing result is abnormal, driving the prompt device on the PCBA to send out abnormal prompt information. The embedded PCBA loads the test code of the pluggable storage to perform a GPS module test, SMT (surface mount technology) of the GPS module can be quickly tested to be good or not, the test result can be read visually, testing efficiency is greatly improved, and hardware guarantee is provided to follow-up normal operation of the whole set.

Description

technical field [0001] The invention relates to a method and system for testing a GPS 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] GPS: Abbreviation for Global Positioning System. [0004] 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 unit...

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

[0010] To sum up, the existing technology for testing the GPS module on the PCBA has problems such as high test cost and cumbersome test process, which have limited the production efficiency of electronic communication products and cannot meet the needs of technological development.
