ELECTRONICS: Ironwood Electronics has recently introduced a new high performance BGA socket for 0.65mm pitch 588 pin BGA. The SG-BGA-7181 socket is designed for 13.5mm x 25.2mm x 1.95mm package size and operates at bandwidths up to 10 GHz with less than 1dB of insertion loss. The contact resistance is typically 20 milliΩ 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 smallest footprint allows inductors, resistors and decoupling capacitors to be placed very close to the device for impedance tuning. The socket also incorporates a new quick insertion method 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 specifically memory functions.
The SG-BGA-7181 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 +100C. The pin self inductance is 0.15nH and mutual inductance of 0.025nH. Capacitance to ground is 0.01 pF. Current capacity is 2A per pin.
Pricing for the SG-BGA-7181 is $1204 at qty 1; with reduced pricing available depending on quantity required.
Samsung's Galaxy line of smartphones used to fare quite well in the repairability department, but last year's flagship S5 model took a tumble, scoring a meh-inducing 5/10. Will the newly redesigned S6 lead us back into star-studded territory, or will we sink further into the depths of a repairability black hole?
In 2003, the world contained just over 500 million Internet-connected devices. By 2010, this figure had risen to 12.5 billion connected objects, almost six devices per individual with access to the Internet. Now, as we move into 2015, the number of connected 'things' is expected to reach 25 billion, ultimately edging toward 50 billion by the end of the decade.
NASA engineer Brian Trease studied abroad in Japan as a high school student and used to fold fast-food wrappers into cranes using origami techniques he learned in library books. Inspired by this, he began to imagine that origami could be applied to building spacecraft components, particularly solar panels that could one day send solar power from space to be used on earth.
