Since the solder balls are touched
by two contacts on each side,
the solder ball damage can be
minimized; additional features
are low actuation force and
compact socket size
We have depopulated versions from existing NP276 base sockets.
As new versions are continually being tooled up we rcommend
to contact Yamaichi for your specific pin count
and matching IC
