CBT-QFN-7008 Dwg

CBT-QFN DIRECT MOUNT, SOLDERLESS SOCKET FOR BURN-IN AND
TEST APPLICATIONS
Features
• Wide temperature range (-55C to +155C).
• High current capability (up to 2.2A).
• Excellent signal integrity at high frequencies.
• Low and stable contact resistance for reliable production yield.
• Highly compliant to accommodate wide co-planarity
variations.
• Automated probe manufacturing enables low cost and short
lead time.
