DESCRIPTION
The M4Zxx-BR00SH SNAPHAT top is a detachable lithium power source for ST’s non­volatile Z ER OPOW ER s urface mou n t SO IC (M H) package (28 pin).
The SNAPHAT top contains a lithium battery and is designed to be "snapped on" after the SOIC is surface mounted on the PC board. Thus th e two piece solution prevents the battery from ha ving t o be exposed to the hi gh temperatures of the sur­face mount process.

MECHANICAL INFORMATION
Electrical connection to the SOIC is made through two pins that connect to the press fitted sockets at one end of the SO IC. Critical contact points be­tween the pins a nd 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 t o provide hi gh point c on­tact 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 separat ing. Th is pack age 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 SNAPHA T 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.

GENERAL NOTES
To remove the SNAPHAT top for replacement, a DIP/IC extractor tool should be used.
Caution: To avoid draining battery do NOT place SNAPHAT pins in a conductive foam.
Caution:Tto avoid damaging SNAPHAT sockets do NOT wave solder SOIC.
