XLT20QFN-1 Soldering Suggestions
This socket is difficult to solder since the device pins
are not exposed, but embedded, into the socket’s
Surface Foot (SF).

You are now ready to attach the QFN header to the SF.

To start, add tack flux to the target land pattern.
Visually align the QFN SF with the target land
pattern. Then solder two opposite SF pins to the
target lands so that the SF does not move
around.
Finish soldering the rest of the SF pins.
If the SF has a middle ground pin, feed solder
through the bottom side of hte target board via
holes. This will connect the center QFN SF pin
to the target board.
Check each solder connection on the QFN SF
pins.
