The
Plastic Leaded Chip Carrier,
or PLCC is a four-sided plastic package that has "J" leads
around its periphery.
These "J" leads occupy less board space than the gull-wing leads that
other packages like the SOIC have. PLCC lead
counts range from 18 to 84. PLCC packages can either be square or
rectangular in shape. The ceramic equivalent of the PLCC is the
JLCC.
PLCC body widths range from .35"to 1.15". PLCCs
have JEDEC-standard package outlines. The standard lead pitch of the
PLCC is 1.27 mm. The PLCC must not be confused with the LCC, which is a
leadless and more expensive ceramic package.
