Mechanical information
Electrical connection to the SOIC is made through two pins that connect to the press fitted
sockets at one end of the SOIC. Critical contact points between the pins and sockets are
gold-plated to resist oxidation. Internally, each socket contains six independent contact
fingers to form redundant connections between the two components. These sockets were
designed to provide high point contact force to provide the lowest possible contact
resistance. The SNAPHAT
onto the ends of the SOIC insuring mechanical and electrical connection even under severe
mechanical shock and vibration. The combined SOIC and SNAPHAT assembly can sustain
shock levels in excess of 100 g without separating. This package also passes variable
frequency testing in accordance with MIL-STD-883, method 2007.2, condition A.

SOIC. The force required to extract the SNAPHAT, and then to re-insert it, reduces each
time. After four or five extractions, the reduction starts to become unnoticeable and the force
required remains at a fairly constant figure. Typically, though, the SNAPHAT will only need to
be extracted and re-inserted once in its lifetime.
