Chipmakers Stress Latest QFN Packages With New Clamshell Burn-In Socket From Semiconductor Test Supplier Antares Advanced Test Technologies

Antares Releases Its New 880 Series Under Deal With Gryphics, Inc. -- a Wholly Owned Subsidiary of Cascade Microtech, Inc.

VANCOUVER, WA--(Marketwire - October 31, 2007) - The world's largest supplier of semiconductor test sockets, Antares Advanced Test Technologies, has released a new clamshell burn-in socket that accommodates standard QFN packages down to 0.35mm pitch -- the 880 Series -- in response to chipmaker demand for sockets that accommodate the latest QFN packages and reduce maintenance-related downtimes on the back-end that affect yield, according to Mark Murdza, Antares' director of marketing.

Many chipmakers have effectively called on burn-in suppliers to deliver QFN sockets that both support finer-pitch packages and make it easy for them to replace and maintain sockets to maximize their production capacities, Murdza said.

Antares will supply its latest QFN socket through its global distribution network under an agreement it established with Gryphics, Inc. -- a wholly owned subsidiary of Cascade Microtech, Inc. (NASDAQ: CSCD) -- in the second quarter of this year.

"The 880 essentially supports our clients' innovation and expands our burn-in portfolio to accommodate lower pitch QFN packages," Murdza said.

Murdza added that the 880's compression mount clamshell is designed to allow chipmakers to remove or replace the sockets and retain production capacity if, for whatever reason, they were to damage them. The socket's wiping-action contact works to create consistent resistance during burn-in and reduce chipmakers' related maintenance and downtimes.

The 880, he said, accommodates QFN packages down to 0.35mm pitch and features a traditional cantilever contact. The socket also features high-performance contacts housed within replaceable contact sets.

The socket's key materials and specifications include its beryllium copper alloy contact, gold contact plating, 20g contact force, temperature rating of -40 degrees C to 155 degrees C and durability of 30,000 cycles.
