  Applications  　PSMPin),FSM(Socket)  ●Stacking(Release type)

Board stacking design (space-saving) is achieved by
sandwiching and soldering pins between PC boards.
Release is made possible by combining pins and sockets;
this type of connection is known as "release type." Suitable
for inserting expansion boards due to model changes, etc.
