2.3.4 Component placement of boards and 
The boards and have to be placed on their bottom sides and on their
top sides. We start with the bottom sides of the boards:
The black phototransistors are soldered into the
soldering pads PT53 and PT54.
You have to pay attention to the polarity:
The short leg must be placed into the
rectangular soldering pad!
PT53 and PT54 are for measuring the motor rotation speed. The
phototransistors have to be put through the hole from the BOTTOM side so
that the shorter leg can be soldered onto the shorter soldering pad.
(If the phototransistors don't fit through the hole you can expand the hole with
a 3 mm drill for some hundredth mm).
Afterwards the legs must be bend over towards the soldering pads:
After bending, the legs must
be trimmed:
