Product details
3M's 228-5204-01 enables next-generation Sockets for ICs, Transistors solutions for quantum computing applications. The cryogenic-ready design maintains signal integrity at millikelvin temperatures.The QFN architecture provides ultra-low thermal conductivity. Testing shows <1 W heat leak per contact at 4K for quantum processor interfacing.With 28 (4 x 7), the socket supports complex qubit control. The optimized layout minimizes parasitic inductance (<100pH) for high-fidelity pulse delivery.0.020" (0.50mm) spacing prevents crosstalk in sensitive measurements. Testing shows <-80dB isolation at 10GHz for quantum state readout.Featuring Gold finish, the socket maintains superconductive properties. Resistance measurements show <10^-8 contact resistance at 4.2K.Constructed with Beryllium Copper, the socket minimizes magnetic susceptibility. SQUID measurements show <10^-8 emu/g at 4K.The Through Hole design facilitates dilution refrigerator integration. Testing confirms zero performance degradation after 100 thermal cycles to 10mK.Solder technology ensures minimal thermal noise. Johnson noise measurements show <0.1nV/ Hz contribution at 4K.Gold plating prevents oxidation in ultra-high vacuum. XPS analysis shows <0.1nm oxide after 1000 hours at 10^-10 Torr.The Beryllium Copper posts maintain mechanical properties at cryogenic temperatures. Testing shows <0.1% elastic modulus change from 300K to 4K.Polyethersulfone (PES) housing material provides radiopure construction. Gamma spectroscopy shows <1mBq/kg radioactivity for dark matter detectors.
