CSP sockets enable testing of any area-array device to +200°C
For the first time, applications that require high-temperature device testing and burn-in, as well as those with high-frequency bandwidth, low inductance and high current conditions, can now incorporate cost-effective and high-reliability CSP socket technology to test and burn-in virtually any area-array device at temperatures up to +200°C. The AR4HT sockets accommodate a variety of area-array devices including BGA, LGA, QFN, DFN, CSP, MLCC and POP as well as bumped die with full and partial arrays. Full socket operating temperature is -55 to +200°C with a life expectancy of more than 10,000 actuations. The socket can accommodate IC devices with a pitch of 0.4 mm or greater as well as mixed pitch environments. The interposer set is comprised of silver particles within a silicon elastomer with a patented polyimide core. Initial contact force is 20 to 30 grams per lead. The socket is available in custom sizes and configurations to suit specific customer applications.
