The new test handling process differs from traditional tube or tray loading of devices into gravity feed and pick-and-place systems. Instead, singulated devices are loaded into a patented micro-spring carrier frame that is handled on Multitest’s strip handling system.
With the InCarrier® device transfer system, Multitest can achieve very high test parallelism for singulated devices without compromising quality through post-test singulation processing. The actual test handling is practically jam-free, even for devices as small as QFN 2 mm x 2 mm, and thus warrants unprecedented tester utilization.
