PLCC TRANSITION SOCKET
A PLCC transition socket and associated hardware is
shown in Figure 4.
FIGURE 4: PLCC TRANSITION SOCKET
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.
The following PLCC transition sockets have been
discontinued:
• XLT68L1: One 68-lead PLCC transition socket
• XLT84L1: One 84-lead PLCC transition socket

Note:
To avoid solder bridging, do not place vias
within 0.025-inch of the PLCC footprint.
Also, any vias near the PLCC should be
directly on the centerline of the pad.
