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 be-
tween the pins and sockets are gold-plated to re-
sist 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 con-
tact force to provide the lowest possible contact re-
sistance. The SNAPHAT top also incorporates
four molded-in retaining clips which hold onto the
ends of the SOIC insuring mechanical and electri-
cal 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 accor-
dance with MIL-STD-883, method 2007.2, condi-
tion A.
Figure 2 illustrates the affect of repeated insertion
and extraction of the SNAPHAT top to the SOIC.
The force required to extract the SNAPHAT, and
then to re-insert it, reduces each time. After three
or four extractions, though, 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.
