Solder QT Py

QT Py

Get the QT Py ready to solder onto the Heart PCB. Castellated pads on the QT Py make it easy to surface mount.

SMD QT Py

Secure the Heart PCB to a stickvise and placed the QT Py PCB on top in the center.

Position

Check the pads on both sides so they fit evenly spaced apart.

Solder QT Py Pads

Place the tip of the iron on the side and add solder. Start by tinning the tip of the iron and add it to one pad using tweezers to keep it in place. After the first pad is soldered, the rest gets easier.

Inspect Pads

To get the most mechanical strength, flood the through-hole pins with solder. Thoroughly check the solder joints are fully touching the pads.
