Burn-In Test: Burn-in test is a process in which components of a system are exercised, monitored and measured in extreme operational conditions such as high temperature, voltage and frequency over time.  The purpose of the environmental and operational stress conditions of burn-in testing is to accelerate and screen early life failures and estimate and monitor long-term degradation and ultimate lifetime.  

System Level Test:  System level test identifies defective SiP products that may not otherwise be screened by traditional wafer level, package level or burn-in testing.  As advanced packaging proliferates and the integration of more individual components into a SiP grows, system level testing becomes more important.  

Test Development Services:  Prior to mass production, an integrated manufacturing ready test solution must be developed and deployed.  Amkor’s test development services offer both co-development and full development of complete test software and hardware solutions to our customers.  These services also enable early engagement with our customers in the product design phases for maximum compatibility with manufacturing.  Our test development teams are experienced in a full suite of test engineering disciplines for Memory, Power, RF, Mixed Signal, Analog and digital test solution development.
