Samtec PLCA Series
adaptors use precision
drawn, spring temper
Phosphor Bronze wire
for high reliability mating
with most common PLCC
sockets. These adaptors
are available with a
choice of surface
mount or through
hole tails and either
full tin plating or
selective plating
with gold on the
contact area of the
terminal.
The insulator is
FR-4 epoxy board,
suitable for most infrared
and vapor phase refl ow
soldering processes. It is
available with or without
alignment pins.
See our Full Line Catalog
for a complete selection
of Surface Mount PLCC
sockets, and adaptors for
Pin Grid Array and Dual
In-Line Package sockets.
