Anyone working in electronics should make time to learn how to solder well. Thankfully it
isn't hard, it just takes practice and having the proper tools. Once you are able to solder well,
your projects will be more professional and more reliable.
Refer to our video “How To Solder” for detailed explanations.

But before you get started, here are a few safety tips that should be followed:
–
Fumes from soldering can be harmful therefore it is important to always have adequate
ventilation.
–
Wear appropriate clothing when working around hot, molten solder. Never wear shorts
or open toes shoes.
–
protect hands and equipment from burns by using a soldering iron holder. An
improperly stored soldering iron is a fire hazard
–
Do not eat, drink, or smoke while you are soldering. Limit exposure to lead.
–
Wash hands often when soldering.
–
Wear safety glasses when soldering.
Purpose of Soldering
Soldering is used to bond two or more metals together. By applying heat to a connection
and feeding solder into this connection, the solder will melt and flow around the metals. A
small surface amount of each of the metals will additionally melt and inter-mix with the liquid
solder forming an alloy. This connection is called an inter-metallic bond and the two metals,
when properly soldered together, act as if it they were one solid, very strong connection.
Importance of Proper Soldering
Proper soldering is the basis for faithful equipment operation. A good solder connection is
physically strong and electrically reliable. A poorly soldered connection will have intermittent
operation which can cause electrical damage to neighboring components. At the very least, a
bad solder connection will create an unpleasant audible experience. Therefore the importance
of good soldering skills cannot be over emphasized. Your sound will rely on it.
Basic Soldering Rules
The following are some basic soldering rules that if followed, will result in reliably soldered
connections every time:
1. Make sure the surfaces to be soldered are clean and free of corrosion. A dirty, greasy,
or oxidized surface will not properly accept solder, creating an intermittent solder
connection. Clean all surfaces prior to soldering.
2. Establish a firm mechanical connection of the components prior to soldering. Solder
should only be used to develop an electrical connection and not a mechanical one.
3. Insure that the soldering tip is clean prior to any soldering. A clean solder tip is one
wiped lightly across a damp sponge to remove oxides prior to use. It is essential for
maximum heat transfer that the tip is shiny and clean.
4. When applying the soldering iron to a connection to be made, it is important to lay the
tip in such a position that the maximum surface area of the tip is against the
connection. In this way, the maximum heat is transferred to the connection in the
