10/22/2002 - Ironwood Electronics’ new high performance Sockets allow 0.5 mm pitch MLF (also called QFN, MLP, LPCC, QLP, HVQFN and LFCSP, just to name a few) IC’s to be socketed and operate without compromising performance in very high speed communication or computing applications. The new 10 GHz bandwidth sockets easily support very dense MLF devices utilizing a high performance conductive elastomer contactor. The socket is a precision device, which guides the IC to the exact position for connection of each lead and uses an aluminum heat sink screw to provide compressive force. The socket shown in the picture is a 10 mm body size SG-MLF-7000. The SG-MLF-7000 accommodates IC packages such as the Amkor MLF68, 0.5 mm pitch.
These patent pending ZIF sockets are mechanically mounted to the target PCB. The socket lid is twisted open, the IC is inserted, the lid is closed and aluminum heat sink screw is rotated to provide downward force on the IC. The sockets are 5 mm high and only 2.5 mm per side larger than the actual IC packages, minimizing footprint on system boards while maximizing system speeds. The socket body and heat sink screw are constructed with aluminum to facilitate heat sinking.
Pricing for the sockets SG-MLF-7000 is $510 at quantity 100.
