Installing Components
Please install the parts in the order shown. After you mount a part, you may solder it in place. Double
check to be sure the part is snug against the printed circuit board (PCB). After soldering, clip the leads
close to the PCB surface.
Use a temperature-controlled soldering iron, set between 700 and 735 degrees F (370 to 390 C). Keep the
tip clean. Use rosin-core solder. Use of improper flux, or improper cleaning procedures may result in
corrosion of the soldered joint. Sometimes this takes days or weeks to appear.
i
It is important that leads be clipped close to the bottom of the PCB. Use a pair of flush-
cutting pliers, or pre-trim the leads before soldering.
As you install the following parts, check the box only
after
you have inspected the solder connection and
clipped the leads (unless directed to not clip the leads).
