CLEANING
(OPTIONAL)
Before you begin to move forward, you might want to
clean
your PCB. You can use e.g. isopropyl
alcohol. Put some of the liquid all over the PCB using the brush, let it act for a while and sweep it off.
Then
just
let
it
dry.
You
can
repeat
these
steps
until
you
are
satisfied
with
the
result.
ICs
Don’t forget to place the two
ICs
into the sockets (
NE5532P
). There is a signed
notch on each IC
that has to match with the
notch on the socket
. Installing ICs can be also a little tricky. You should
bend the IC leads in slightly with your fingers first. Then press all the leads into the sockets in one
shot
