52GHz Bandwidth Socket for 035mm Pitch BGA
Ironwood Electronics introduced a new high-performance elastomer socket for 0.35mm pitch BGA package.
Ironwood Electronics recently introduced a new high-performance elastomer socket for 0.35mm pitch BGA package. The SG25-BGA-2054 socket is designed for a 2mmx2mm package size and operates at bandwidths up to 52 GHz with less than 1dB of insertion loss (GSSG configuration).
The contact resistance is typically 20 milliohms per pin. Network analyzer reflection measurements for the G-S-S-G case were taken with all except the pins under consideration terminated into 50 Ohms. The socket is mounted using supplied hardware on the target PCB with no soldering and uses the smallest footprint in the industry—only 2 mounting holes. The smallest footprint allows inductors, resistors and decoupling capacitors to be placed very close to the device for impedance tuning. The socket also incorporates a simple swivel hardware installation method so that IC's can be changed out quickly. A spring-loaded compression plate is integrated into the swivel lid.
The SG25-BGA-2054 sockets are constructed with high performance and low inductance elastomer contactor. The temperature range is -35C to +100 C. The pin self inductance is 0.06 nH and mutual inductance of 0.019 nH. Capacitance to ground is 0.129 pF and mutual capacitance is 0.017pF. Current capacity is 2 amps per pin.
About Ironwood Electronics
Ironwood Electronics is ISO9001:2008 certified and offers a wide selection of high performance adapters and sockets, plus experienced engineering for quick-turn customs. Ironwood Electronics offer probing, prototype, and SMT package emulation for all SMT packages. Ironwood Electronics products include High-bandwidth 40 GHz sockets for BGA/QFN, pitches down to 0.3 mm, only 2.5 mm larger than IC. Latest adapters include QFN/MLF package emulators, BGA high endurance test sockets, BGA production adapters, and back-to-back Xilinx-compatible BGA sockets. These adapters/sockets support the product life cycle. In the design cycle, engineers are able to test and develop products more quickly with Ironwood prototype and test adapters for all package type--along with the very high density 40 GHz BGA and QFN/MLF sockets. In production, Ironwood can help extend the product life of PCBs, using package converter technology to replace or upgrade original or obsolete components and provide small to high volume turn-key solutions.
