Place the VCF 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 some resistors, switching

diodes and the power protection

diodes. Bend the resistor leads and insert

them in the relevant places according to the

part placement diagram above. All compo-

nents on the PCB have both their value and

denomination printed onto the silkscreen. If

you are not sure about a resistor’s value, use

a multimeter to double-check. Next, insert the

diodes. Remember – when inserting the

diodes, orientation is critical! A thick

white 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.
