Multitest, a designer and manufacturer of final test handlers, contactors and load boards used by integrated device manufacturers (IDMs) and final test subcontractors worldwide, 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 (DUT) 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. For more information, visit http://multitest.com/mercury/.
