Transition Socket Specification
QFP TRANSITION SOCKET
QFP (MQFP, TQFP, PQFP) transition sockets and
associated hardware are shown below.
FIGURE 5: QFP ONE-PART TRANSITION
FIGURE 6: QFP TWO-PART TRANSITION
The QFP transition socket is required for use along with
the QFP device adapter. The device adapter is
equipped with four socket strips that interface with the
transition socket.
Microchip offers the following QFP transition sockets:
One-Part:
• XLT44PT: One 44-lead QFP transition socket,
• XLT64PT1: One 64-lead QFP transition socket,

To avoid solder bridging, do not place vias
within 0.025-inch of the QFP footprint.
Also, any vias near the QFP should be
directly on the centerline of the pad.
The XLT64PT1 for the PIC16C92X is not
symmetrical. Please note Pin 1 orientation
prior to soldering to the target system.
