Appendix B - A Note About Safety
Burns to your skin can be very painful and can lead to serious injury.
Burns to your eyes can be catastrophic.
Toxic fumes can cause serious harm.
Flying objects such as wire ends etc. can cause painful and serious injuries.
When building your kit please remember that Soldering Irons and Solder are used at High
Temperatures !
Soldering Irons can remain hot for many minutes after being turned off. Never touch the tip to see
if it is hot. Touch the tip to a wet pad to test for temperature.
Wear safety glasses to protect your eyes from flying objects.
Appendix C - Soldering Basics
1. Insert component leads into PCB holes and bend them back slightly to hold the part in
place. You can either trim the lead now or wait till after the joint is soldered. I usually
install several parts at one time and then solder and trim multiple leads.
2. Place a hot and clean iron tip against both the lead and pad as in Fig. A1.
Fig. C1 - Form a heat bridge
3. Create a heat bridge between the lead, the PCB pad and the iron by placing a small amount of
solder on the tip.
4. Apply solder around the outside edge of the pad as in Fig. A2. If the pad and lead are at the
correct temperature, the solder will flow around the connection.
