Understanding HALT application in desktop, NB and Server

Application of HALT at design stage becomes more and more common in electronics industry. Many discussions and disputations of the HALT test interpretation are in full swing. With our HALT test experiences in notebook, desktop and server products, we intend to share and discuss the safety factor of exact product operating limits to its operation specifications in temperature and vibration and common failure modes stimulated thereby. A general perspective of the test setup techniques by product types and its influence is also provided. The distinctive roles of HALT on board level and system level from thermal flow field point of view are also shared in this paper.
