Handler runs characterisation in hot, cold temperatures

Keywords:MT2168? cold for characterisation? handler?

Test handling and interface solutions manufacturer Multitest released a pick and place handler that can characterise devices at cold conditions, addressing the evolving requirements for temperature performance driven by applications in the end markets.

Whereas final test of devices in high volume production will only be done at ambient or hot, they need to get qualified for cold conditions before they ramp. The MT2168 offers the "cold for characterisation" option to allow engineers to utilise the same platform for qualification and final test without the need to invest in more complex and more expensive tri-temp test equipment.

The "cold for characterisation" set-up of the solution is an add-on to the standard base unit, which does not require changes in the handler itself. All required features are part of the conversion kit set. The engineer can decide, whether he wants to use existing external chillers or if he prefers to have a LN2-based heat exchanger integrated. The option provides temperature conditioning directly at the contact site and sticks to the chamberless concept of the MT2168. This way, no icing issues or defrost needs occur.

"With changing temperature performance requirements in the consumer markets and new car convenience and car entertainment applications in the automotive market, we anticipate a shift from strict tri-temp test in volume production to cold qualification before ramping," said Gnther Jeserer, VP for Gravity and Pick & Place Handling. "The MT2168 is the only handler with this ability."
