Abstract
Manual ball drop testing for device displays can be prone to inconsistencies in drop height and location, which may lead to test variation. A disclosed system automates this process using a vertically-mounted motorized linear stage with an attached electromagnet to hold and release an impactor, for example, a steel ball. A user can input a desired drop height via a software-driven graphical user interface, which directs the linear stage to position the electromagnet at the specified height. The electromagnet is then deactivated to release the impactor onto the display under test. This approach can provide a repeatable and efficient method for conducting ball impact testing, which may reduce manual labor and improve the consistency of test results for device reliability assessment.
