8 / 16 page Mechanical information M4T28-BR12SH, M4T32-BR12SH 8/16 4 Mechanical information Electrical connection to the SOIC is made through four pins that connect to the four press fitted sockets at each 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 with high point contact force to provide the lowest possible contact resistance. The SNAPHAT® top also incorporates four molded-in retaining clips which hold 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. 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 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. Figure 2.
