April 19, 2011 — Multitest, a designer and manufacturer of final test handlers, contactors and load boards, announced that its ECON test contactor exceeded 4.5 million insertions at an Asian test house.
The customer was able to run a high-volume application with more than 100k throughput per day at an octal-site set up for more than 1.5 years without contactor-wear related test cell downtime. The contactor performance resulted in a 99% stable test yield.
In this test cell set up, the overall performance also benefitted from the Multitest Plug & Yield program. The test house used the ECON together with the Multitest MT9928 test handler.
The ECON socket was launched for high-power applications of small size and small pitch devices (QFN). It also is available for SO, QFP and QFN packages with a lead pitches down to 0.25mm.
Multitest’s proprietary coatings ensure long life spans and high first pass yields. The high first pass yield results from a precise contact spring geometry and the use of a new type of plastic material that avoids thermal expansion. A high contact force of 0.45N per spring ensures repeatable electrical behavior. Additionally, the ECON socket is load-board compatible with existing RFC sockets and third party socket types. It also supports plunge-to-board applications in the full ambient-hot-cold temperature range.
Multitest designs and fabricates test equipment — contactors, boards and test handlers — for semiconductors. For more information, visit www.multitest.com.
