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’s Castle handlers incorporate a patented vertical tray handling system that provides high input/output automation in an extremely small footprint. The system is available in both memory and logic configurations. Castle Mx32 provides parallel testing of up to thirty-two devices. Castle Lx offers the same small footprint as the Mx32. Castle EC is interface compatible with the existing Castle Lx system and permits the addition of external process modules, such as input loading, extended sort categories, laser mark, etc. Delta’s Castle Lx is a hot and cold pick-and-place handler and it is capable of thermally conditioning devices from -60C to +160C. The Lx can position from one to nine devices for testing. Its large thermal soak area provides a steady flow of thermally conditioned devices to the test site allowing the handler to process parts at high speed when running at temperature. The Castle contains an innovative vertical tray storage system which saves space on the test floor by minimizing the handler’s footprint.

The Delta Design Burn-In System utilizes a versatile circuit board approach which allows the mounting of any combination of device sockets. An internal load rack design accommodates a density of greater than one device per cubic inch of chamber space (for 14-pin DIP devices), mounted in a useable space of 7” x 10” per board. The environmental chamber provides flexible rear wall seals which allow the circuit board connectors of the device under test to be outside the high temperature environment.

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.

Monitoring of temperature excursions between two present limits is provided by the Temperature Monitor. If limits are exceeded, power to the monitored unit is removed, a warning lamp is illuminated and an audible alarm is activated. When temperature is again within limits, the monitor may be reset for continued operation. A combination pyrometer scale provides reading at a glance with both Fahrenheit and Centigrade ranges.

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).
