Ironwood's GT sockets are ideal for prototyping and testing almost any BGA or QFN device application. These IC sockets provide excellent signal integrity yet remain cost effective. Innovative elastomer interconnect technology that delivers low signal loss (1dB at 75GHz) and supports BGA or QFN packages with pitches down to 0.15mm was utilized in these sockets. GT BGA sockets are mechanically mounted over a target system's BGA lands using mounting and alignment holes at proper locations (page 2 of the individual socket drawing shows recommended PCB layout information). These low-profile sockets are only 2.5 mm per side larger than actual IC packages (industry's smallest footprint).

BGA sockets and QFN sockets using GT contact technology provide >75GHz signal speed in a smallest footprint for prototype and test applications. These sockets support pitches from 0.15mm to 1.27mm. Standard sizes typically ship within 5 days ARO.

GT is a new elastomer technology that has silver particles held in a conductive column like buttons which are embedded in a non-conductive polymer substrate on a proper pitch that provides high compliance and extreme temperature ranges. GT is available for BGA, LGA, QFN, PoP and other packages from 0.15mm to 1.27mm pitch. The contact resistance is <30 milliohms. The operating temperature range for the elastomer is -55°C to +160°C.
