Socket your High Speed QFP IC using elastomer socket with superior electrical performance
Ironwood Electronics has recently introduced a new high performance QFP socket for 0.508mm pitch 132 pin QFP. The SG-QFE-7025 socket is designed for 19.39mm x 19.39mm x 4.22mm package size with 24.79mmx24.79mm lead tip to tip and operates at bandwidths up to 30 GHz with less than 1dB of insertion loss. The contact resistance is typically 20 milliohms per I/O. The socket connects all pins with 30 GHz bandwidth on all connections. The socket is mounted using supplied hardware on the target PCB with no soldering, and uses smallest footprint in the industry. The smallest footprint allows inductors, resistors and decoupling capacitors to be placed very close to the device for impedance tuning. The socket also incorporates swivel lid with compression screw, so that IC’s can be changed out quickly. The socket features a floating compression plate made out of Ultem1000 material to force down the QFP leads on to elastomer. There is also a hard stop feature built into the compression mechanism.
The SG-QFE-7025 sockets are constructed with high performance and low inductance gold plated embedded wire on elastomer as interconnect material between device and PCB. The temperature range is -35 °C to +125 °C. The pin self inductance is 0.15 nH and mutual inductance of 0.025 nH. Capacitance to ground is 0.01 pF. Current capacity is 2 amps per pin.
