The Application of Ping-pong Mode in IC Production Test
With the current international IC packaging and test industry constantly transferring to China,more renowned international companies in China hope to find low cost but high quality solutions.Testing cost is an important part of the whole IC industry chain which makes sure the quality of the IC.Statistics show that many IC testing costs are more than 45% of the whole IC production cost,so low testing cost can dramatically reduce the IC manufacturing cost.The expensive Automatic Test Equipment(ATE) is the main factor leading to high cost of testing,using the ATE effectively needs to be explored and studied.The ping-pong test mode that has been detailed introduced in this paper,which can make full use ATE resources and reduce the IC test cost effectively.
