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
