Place the Mixer PCB in a PCB holder for
soldering or simply on top of some spacers
(I use two empty solder wire coils here).
I usually start populating PCBs with lower,
horizontally placed components. In this case,
these are power protection diodes. Bend
the diode leads and insert them in the rele-
vant places according to the part
placement diagram above. Remember –
when inserting the diodes, orientation is
critical! A thick white or black stripe on the
PCB indicates the cathode of a diode –
match it with the stripe on the component.
Flip the PCB over and solder all components.
Then, use pliers to cut off the excess leads.
Next, insert the DIP socket, hold it in
place and solder one of the pins. Make sure
the DIP socket is oriented correctly – the
notch on the socket should match the notch
on the PCB’s silkscreen. Now, turn the PCB
around and solder all remaining pins of the
DIP sockets. Then proceed with the
ceramic capacitors. Place the PCB in your
PCB holder or on spacers, insert the
capacitors and solder them like you did with
the diodes before. After this procedure
PCB should look like this:
