Breadboarding Techniques
This section contains information which may prove useful when constructing circuits using the
PB-503A. While there are no hard and fast rules for breadboarding, the following tips may save
time and trouble.
Unless a circuit is being prepared for a demonstration or display, avoid cutting component
leads very short. While short wires and leads may look neat, the clipped components will only
fit into a limited “span” of connector sockets, limiting the use of the component. It is perfectly
permissible to use untrimmed components while exploring different circuit possibilities.
The only time short leads may be necessary is when operating at higher frequencies and
experiencing mysterious malfunctions. Sometimes the only way to correct high frequency
circuit problems is to shorten all circuit connections.
Be especially careful when inserting integrated circuits into the breadboard sockets. Unless
the IC pins are straight, it is very easy to crush the pin into a zigzag shape or fold the pins
underneath the body of the IC. Either way the result is a bad connection or no connection
at all.
Always use solid wire for breadboard connections. When stripping the wire ends, be careful
not to strip more than about three-eighths of an inch of insulation from the wire. Too much
bare wire may result in unintentional connections near the wire end.
After you have built up a few circuits, you will have a good collection of pre-stripped jumper
wires. Save them. By reusing these wires, you can save even more time and effort in
assembling future circuits. Pre-formed wires in various sizes are also available from Global
Specialties (please visit web site for available options and accessories).
