Abstract

The invention relates to a keyboard testing system of an intelligent mobile phone and a testing method thereof. The keyboard testing system of the intelligent mobile phone comprises a computer, a testing board connected with the computer through an asynchronous serial interface and a mobile phone main board connected with a testing tool through the asynchronous serial interface. A keyboard interface on the mobile phone main board is connected to a plurality of analog switches on the testing board through the testing tool; and an ARM on the testing board is connected with the analog switches on the testing board through an IC bus. The keyboard testing system of the intelligent mobile phone and the testing method thereof are used for testing the keyboard of the intelligent mobile phone after adopting the mobile phone main board surface mount technology (SMT) and can provide simple operation for production workers, provide a simple judgment basis to obtain accurate detection results, reduce the number of production personnel and the production cost, improve the production efficiency, and improve the product quality.

Description

technical field [0001] The invention relates to a keyboard test system and a test method for a smart phone, in particular to a keyboard test system and a test method for a smart phone after the surface mount technology (SMT) of the main board of the mobile phone. Background technique [0002] At present, in the fiercely competitive mobile phone market, it is required to respond quickly to customer needs. In addition to competition in terms of product cost performance and appearance, there is also pressure on the delivery cycle. On the premise of ensuring the quality of the produced products, we must Increase daily production capacity. To increase daily production capacity, there must be an efficient testing method. First, intelligence; second, high efficiency; third, simple operation. At present, some mobile phone manufacturers with large-scale production still use manual key operations, and detect whether there is a correct display judgment on the mobile phone display scr...
