QFP TRANSITION SOCKET
QFP (MQFP, TQFP, PQFP) transition sockets and
associated hardware are shown below.
FIGURE 4: QFP TRANSITION SOCKET
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.
There are two parts to the QFP transition socket:
1.
2.
Microchip offers the following QFP transition sockets:
• XLT44PT3: One 44-lead QFP adapter socket and
• XLT64PT5: One 64-lead QFP adapter socket and
• XLT80PT2: One 80-lead QFP adapter socket and
• XLT80PT3: One 80-lead QFP adapter socket and

QFP header that gets soldered down to the
target application
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.
