Test Development Engineering
A fraction of the customers develop their own complete test solutions and offload to Amkor for production. Amkor can enable co-development, or full development, of complete test software and hardware solutions. Engage with us early in the product design for maximum impact or come to us later in the product lifecycle for significant cost savings with migrations to more cost-effective testers and/or higher parallelism.
