Analysis and Improvement of Constant Acceleration Test Fixtures for Electronic Components
In the field of military industry,constant acceleration exists in most environments.In order to determine the impact of centrifugal force on the device and evaluate whether there are structural or mechanical defects in the component,military units often incorporate constant acceleration testing in the reliability screening process of the component.Due to the complex internal structure of the device,the chip,lead wire,substrate,and packaging shell are very compact.How to design a suitable constant acceleration test fixture to ensure that structural defects can be detected during the screening process without damaging the components has become an important consideration factor in fixture design.This article addresses the problems of several fixing methods in constant acceleration testing.By optimizing fixture design and experimental verification,a new type of constant acceleration testing fixture system is proposed.This fixture can effectively improve detection efficiency and ensure that the appearance of the product is not affected during the testing process.
