Elastomer Socket for Infineon's BGA221

Mar 11, 2011

Ironwood Electronics has recently introduced a new high performance BGA socket for 0.4mm pitch 221 ball BGA - SG-BGA7162.

Socket your 0.4mm pitch BG221 using GHz bandwidth elastomer socket

The socket operates at bandwidths up to 10 GHz with less than 1dB of insertion loss. The contact resistance is typically 20 milliohms per I/O. The socket connects all pins with 10 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 socket also incorporates a new quick insertion method using shoulder screws and swivel socket lid so that IC's can be changed out quickly. The application of the socket is to verify the function of IC in a development system with superior electrical performance.

The socket also features independent compression mechanism to accommodate package manufacturing variations. The specific package sizes accommodated by the socket are 0.4mm pitch 7mm x 7mm, 17x17 ball array. To use, drop IC into the socket, place floating compression plate, swivel the lid, and apply down force using compression screw.

The SG-BGA-7162 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 -35C to +100 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.

Pricing for the SG-BGA-7162 is $352 at qty 1.
