Transition Socket Specification
QFP TRANSITION SOCKET
QFP (MQFP, TQFP, PQFP) transition sockets and
associated hardware are shown below.

QFP Transition Socket
Target/Application Board
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.
QFP TRANSITION SOCKET
SOLDERING TIPS
? Use controlled soldering iron tip temperatures
between 300 ? C and 325 ? C (570 ? F to 615 ? F)
? If possible, use a PACE mini wave soldering iron
tip or an equivalent tip design.
? Plan to solder one (1 of 4) side first, then the
opposite side, then the remaining two sides.
? Soldering iron tip movement should be in the
direction of the leads (backward and forward), not
across the leads; dragging the tip across the
leads may cause lead damage.
? Use generous amounts of soldering flux to aid in
the solder flow action.
Note:
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.
There are two parts to the QFP transition socket:
1.
2.
Adapter socket that connects to the QFP device
adapter
QFP header that gets soldered down to the
target application
Microchip offers the following QFP transition sockets:
? XLT44PT3: One 44-lead QFP adapter socket and
one 44-lead QFP header (0.8 mm)
? XLT64PT5: One 64-lead QFP adapter socket and
one 64-lead QFP header (0.5 mm)
? XLT80PT2: One 80-lead QFP adapter socket and
one 80-lead QFP header (0.65 mm)
? XLT80PT3: One 80-lead QFP adapter socket and
one 80-lead QFP header (0.5 mm)
See the drawings in this section for layout dimensions
and clearances for tall components.
