概述

Delta’s Orion system is a test-on-strip handler. In pick-and-place and gravity-feed handlers, ICs are processed in single packages, after they are excised from leadframes or laminate substrates. In test-on-strip, ICs are tested on the leadframe or substrate and are separated in a subsequent operation. Test-on-strip may provide advantages in some applications, such as when testing very small ICs and when testing multiple ICs simultaneously (parallel testing).
