Jupiter Gravity Feed

The Cohu Jupiter Gravity Feed is a test-and-probe handler for semiconductor devices. The Cohu Jupiter Gravity Feed Handler is a tri-temp semiconductor handler with auto loading and unloading and tube-based input and output characteristics.^[2]

The Cohu Jupiter Gravity Feed uses automatic loading and unloading and supports tube-based input and output. The Cohu Jupiter Gravity Feed has input tube stack height of 2 x 275 mm and output tube stack height of 1 x 275 mm. The Cohu Jupiter Gravity Feed has soak capacity up to 16 tubes and desoak capacity up to 16 tubes. The Cohu Jupiter Gravity Feed is specified as a 300 mil single-site configuration.^[1][2]

The Cohu Jupiter Gravity Feed is a tri-temp handler with a temperature range of -60 °C to +175 °C. The Cohu Jupiter Gravity Feed has soak time accuracy of +/- 2 °C and test site accuracy of +/- 2 °C. The Cohu Jupiter Gravity Feed has guard band down to +/- 1 °C. The Cohu Jupiter Gravity Feed has TTL parallel and RS 232 as standard electrical interfaces, with IEEE 488 optional and USB at OPI as standard. The Cohu Jupiter Gravity Feed is specified for throughput up to 10,000 uph and index time down to 750 ms.^[1][2]

Test handlers of this class sit in the back-end device flow around final electrical test and related screening operations. Test handlers are used after assembly and packaging, when finished devices need temperature-conditioned electrical verification before packing, binning, or downstream quality operations.

The Cohu Jupiter Gravity Feed is intended for semiconductor device handling in test-and-probe use. The Cohu Jupiter Gravity Feed combines tube-based part presentation, automatic loading and unloading, and tri-temp operation for temperature-conditioned test handling.^[2][1]
