Soldering in Industry

What is Soldering?

• Soldering is the process of
• a making a sound electrical
• and mechanical joint
• between certain metals by
• joining them with a soft
• solder.

5
What is Solder?

• Standard 60 tin, 40 lead alloy with a
  non-corrosive flux core
• Flux is a chemical designed to clean the surfaces
  of deposited oxides, and to exclude air during
  the soldering process, which would otherwise
  prevent these metals coming together.
• Solder comes in gauges like wire.
• Lead is poisonous and you should always wash your
  hands after using solder.

Before Soldering (cont.) . . .
Make sure before you plug in your soldering iron
that the cord does not have any cuts or breaks.

• You do not want to get electrocuted

7
Before Soldering . . .
Make sure that you are wearing proper eye
protection.

Soldering Techniques

• Plug in the soldering iron.
• When the iron is hot, apply some solder to the
  working end of the bit, and wipe it on a piece of
  damp cloth or sponge to form a thin film on the
  bit. This is called tinning.
• Contact both parts of the joint with the tip. The
  solder will make a good electrical and mechanical
  joint if the joints are at an equal high
  temperature.
• Apply the solder to the joint. The solder will
  melt immediately and flow around all the parts.
• After a few seconds remove the iron from the
  joint. Make sure that no parts of the joint move
  until the solder is completely hard.

Proper Solder Joints
Use the right amount of solder Too little solder
will give the joint a half finished appearance
too much and the solder will glob. Remember it
is much more difficult to correct a poorly made
joint than it is to make the joint properly in
the first place.

Soldering Video

• Soldering Video a great soldering
  demonstration, however there is no sound so you
  must read the captions on the right-hand side of
  the screen
