Handlers in semiconductor test move packaged devices through a controlled sequence of loading, presentation to the test interface, sorting, and unloading. Handlers are used to automate device flow around electrical test equipment and to keep device orientation and site assignment consistent during high-volume screening.

A semiconductor handler transfers packaged parts from input media to test positions, presents the parts to one or more test sites, and then routes the parts to output destinations based on the test result. A handler typically coordinates indexing, part pickup or transfer, device orientation, contact presentation, and binning while a separate tester performs the electrical measurements.

Handlers sit in the back-end test flow after device assembly and before final packing or shipment release. A handler is used when singulated packaged devices need automated presentation to electrical test hardware for screening, classification, or final verification. A handler is downstream of package assembly and upstream of final pack and logistics steps.

Semiconductor handlers are used for automated electrical test of packaged integrated circuits and other discrete semiconductor parts. Handler platforms support production environments that need repeatable device presentation, multi-site throughput options, and sorting by test outcome.
