3.1. All resistors (except R4) leads bend in accordance with this picture that each
resistor place on board surface will be minimal.
3.2. By using long nose pliers, bend inductor L1 leads. Bending the
leads directly near casing may discontinue this inductor coil wires
that are soldered to leads.
3.3. Bend the capacitor C1 leads.
3.4. Repeat actions pointed in items 2.5, 2.5.1 and 2.5.3 for proper components insertion into the PCB
and soldering.
