Mobile Phone Keypad Test with USB Data Acquisition Device
应用文章
Mobile phones have been an essential gadget for the past few years, with users of all ages. In an attempt to attract customers, mobile phone manufacturers have reduced the size of mobile phones tremendously and this leads to smaller numeric keypads. These numeric keypads are tested to ensure their ease of use. One important measurement is the force on the keypad. In order to meet the force specific cation, the force should be low enough for use but not so low that it allows accidental activation of the keyboard.
Keypad Test
A basic keypad test system consists of a universal test machine. It is equipped with a low-capacity force sensor fixed on the test arm. In addition, a T-slot table is used to support the phone or keypad module. In this test, the prong will simulate the motion that occurs when a mobile phone user presses a button on the keypad. During this test, the load profile and displacement characteristic of the keypad are monitored.
