Surface-mount test sockets
Staff -- Test & Measurement World, 5/1/2005
Dimensions Consulting has announced a new surface-mount BGA test socket for use with high-speed Serdes applications operating beyond 10 Gbps. In addition, the company announced a test socket for CSP and QFN devices. The socket for use with high-speed Serdes applications is based on a Pogo design with dual independent plungers to optimize force and deflection. In 1-mm pitch applications, each pin exhibits a rise time of less than 40 ps and an insertion loss of 2 dB at 40 GHz with an inductance of 0.6 nH.
The pins employ a radius interface to printed-circuit boards to extend board life; a self-cleaning DUT plunger minimizes solder contamination. A version is also available for lead-free packages.
The new surface-mount test socket for CSP and QFN devices can be used for frequencies beyond 30 GHz. Available in pitches from 0.4 mm to 0.65 mm, it uses injection-molded lids and frames that are configurable per package; 3-mm Pogo-pin-style contacts connect a board and a DUT.
Base price: $550 per socket plus $6 per pin. Dimensions Consulting, www.dci-us.com. .
