Cohu acquires Delta Design, supplier of test handling solutions.

The Delta MATRiX is a high performance pick-and-place handler that provides increased productivity in several dimensions of performance: up to three times higher throughput, four times higher parallelism, and active thermal control per test site. With an adjustable test site configuration, customers can reuse existing load-boards, including boards made for gravity handlers. The system also provides flexibility with field upgradeable options including a chamberless tri-temperature test site and auto contactor cleaning.

Delta 1888 handler for RF/Wireless handling applications. The 1888 is a gravity-feed handler designed specifically for handling RF/Wireless ICs. High frequency devices require special handling to ensure the maximum yield is obtained from the test cell. The 1888 has been designed to create the optimum RF testing environment.

The Delta Flex™, available in three models with various levels of automation, provides hot/cold test capability and broad versatility in IC package and media (tray or tube) handling. Through Delta’s continuous product improvement process, the handler has been successfully adapted to meet the evolving needs of IC manufacturers.

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).

ORION

One of Delta Design’s original offerings, the Delta 40xx series handler is specifically designed to run carrier mounted devices from 3/4" up to 4". These original Delta Design handlers are very well suited for either production lots of carrier mounted devices or engineering lots for custom packages that can be mounted in a carrier. Both handlers also feature 30 minute change over time, vertically mounted contactors, and plunge style contactors that can be retrofitted for plunge to board applications. Single site, Tri-temperature (-60°C to +160° ± 1°C), Carrier mounted devices 3" up to 4" (PGA, QFP, Flat Pack, LCC, PLCC, Hybrid + Custom), UPH ~750, Single sleeve input, 5 sleeve output featuring closed loop positive binning.
