SO 2000

The Rasco SO 2000 is a semiconductor test handler. The SO 2000 is a modular gravity handler for small devices. The SO 2000 is designed for tube-to-tube and bowl-to-bulk handling configurations. The SO 2000 is available in single, dual, and quad configurations. The SO 2000 supports up to four test sites in parallel.^[4][5]

The SO 2000 uses a gravity-handler architecture with various input and output possibilities. The SO 2000 provides tube input and output and also supports bowl input with bulk output. The SO 2000 features a fast plunger with up to four plunger heads. The SO 2000 has index time down to 450 ms. The SO 2000 has throughput up to 14,400 UPH. The SO 2000 supports full split kit capability so one handler can handle two different packages.^[4][5]

Test handlers sit after assembly and singulation in the manufacturing flow for integrated circuits and similar packaged components. Test handlers operate alongside automated test equipment by positioning each packaged part for contact during electrical test. Test handlers are followed by binning, packing, and other downstream device disposition steps based on the test outcome.

Test handlers of this class are used for packaged semiconductors that are small enough to be singulated and moved through mechanical tracks or tubes. Such equipment commonly supports electrical screening, temperature characterization, and production sorting for analog, sensor, logic, and discrete style packages. Gravity handlers are especially suited to package families that can move reliably by controlled mechanical feed without wafer-level handling.
