PLCC Transition Socket
Target/Application Board
The PLCC transition socket is required for use along
with the PLCC device adapters. The DAF18-1 device
adapter is equipped with eight socket strips that inter-
face with one of two transition sockets. The DAF18-3
device adapter is equipped with four socket strips that
interface with one transition socket.
The PLCC transition sockets are designed with a
threaded insert in the center of the footprint so that a
4/40 screw can securely fasten the transition socket to
the device adapter.
The PLCC transition sockets are designed to be sol-
dered to the target PCB PLCC surface mount pattern or
inserted into a PLCC socket on the target PCB.
