Multitest announces that its Mercury contactor with Q-tip successfully passed a two-month evaluation at a US-based IDM with test operations in Southeast Asia with excellent first-pass yield for more than 500k insertions. Single point spring probes face limitations in terms of targeting a large enough area to ensure contact with device under test pads over the full temperature range of -55° to 150°C.
Multitest studied how materials change over various thermal conditions and applied this knowledge to provide optimum probe targeting.

The triple edge tip geometry of the Q-tip design improves probe to DUT pad alignment targeting, especially over all ranges of temperature testing. Improved targeting means more reliable contact and higher first pass yields.

The Mercury Q-tip demonstrated superior performance during the tri-temp high volume evaluation on a 0.4 mm pitch QFN application.
