The board also has polarising orientation
marks within the idents. The square solder
pad is the plus and the round, the minus.
On these boards, the plus side also has a
(+) symbol next to it. So, as per the pic to
the right, the long leg goes in the square
hole!..
Again, as before, bend the leads outwards
to hold the component in place.
Both Capacitors now in place. Check
polarity one more time before you turn the
board over to solder.
Capacitors ready to be soldered.
