Transition Socket Specification
RECOMMENDED INSTALLATION OF
TRANSITION SOCKETS WITH
CABLES
For transition sockets that use a cable, follow these

instructions for installing your transition socket on the
target board.
PCB Layout Considerations:
Make sure you leave enough room on the PCB to
accommodate the cable, i.e., space your target pads
for each device far enough apart so that the cable from
one pad group will not interfere with another pad group.
