Clamshell Burn-in Sockets for Standard QFN Packages

The 880 series of clamshell burn-in sockets accommodates standard QFN packages down to 0.35mm pitch. The 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. It 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°C to 155°C and durability of 30,000 cycles. Antares released the 880 series under a deal with Gryphics Inc., a wholly owned subsidiary of Cascade Microtech Inc. Antares Advanced Test Technologies, Vancouver, WA,
