CAUTION:
Solder residue usually contains lead, which is poisonous if you ingest it. Do not
breathe the fumes, do not eat the supplies, wash your hands after you handle solder, and
sweep and wipe up your work space after EVERY USE.
Most of the components in your Altura MkII+ kit will be soldered to the printed circuit board (PCB);
only the distance sensors and the display board will be attached to the board via headers. All of the
components will be installed from the “component side” of the board, which is the side that has the
part labels printed on it. The other side of the board is called the “solder side,” which, as the name
implies, is the side on which the legs of the components will be soldered. Proper technique for installing
and soldering components to a circuit board is demonstrated through several great resources on
Instructables and Youtube under the search “PCB soldering tutorial.” The general procedure consists
of the following:
1.
Install the part on the “component side” of the board, by pushing the legs of the components
through the appropriate holes in the board. For your convenience, the board has silk screen outlines
indicating where the components should be placed, along with text indicating the part number and the
component value.
2.
Hold the component in place with your finger and turn the board over.
3.
Tack one of the component legs on the solder side of the board with a small bit of solder
4.
Once the component is secured, thoroughly solder the rest of the legs.
5.
Go back to the original leg that was first tacked down and re-solder it.
