Hello Guys,
Today we are gonna be talking about soldering and its
equipment’s
Most people do ask what does soldering mean well soldering
simply means the process in which two or more metal items are joined together
by melting and then flowing a filler metal into the joint—the filler metal
having a relatively low melting point. Soldering is used to form a permanent
connection between electronic components.
The metal to be soldered is heated with a soldering iron and
then solder is melted into the connection.
Only the solder melts, not the parts that are being
soldered.
Solder is a metallic "glue" that holds the parts
together and forms a connection that allows electrical current to flow.
You can use a solderless breadboard to make test circuits,
but if you want your circuit to last for more than a few days, you will want to
solder the components together.
MATERIALS AND
EQUIPMENTS
- A
soldering iron
- A
soldering iron is used to heat the connections to be soldered.
- For
electronic circuits, you should use a 25- to 40-watt (W) soldering iron.
- Higher
wattage soldering irons are not necessarily hotter; they are just able to
heat larger components. A 40-W soldering iron makes joints faster than a
25-W soldering iron does.
- A
soldering iron can be purchased at hardware stores and at most large
department stores.
- Rosin
core solder
- Solder
has a lower melting point than the metals that are being connected do.
The solder melts when it is heated by the soldering iron, but the metals
being joined will not melt.
- The
rosin core acts as a flux. It prevents oxidation of the
metals that are being connected, and enhances the ability of the solder
to "wet" the surfaces that are being joined.
- Solder
that is used to join copper pipes has an acid core, which is appropriate
for pipes, but will corrode electronic connections. Use solder that has a
rosin core.
- For
most electronics work, a solder with a diameter of 0.75 millimeters (mm)
to 1.0 mm is best. Thicker solder might make soldering small joints
difficult and also increases the chances of creating solder
bridges between copper pads that are not meant to be connected.
- An
alloy of 60/40 (60% tin, 40% lead) is used for most electronics work, but
lead-free solders are available as well.
- Stand
on which to hold the hot soldering iron
- There
are a variety of stands available. It is important to always keep the hot
iron in its stand when not in use.
- Sponge
- The damp sponge is used to clean the tip of the iron .
- Solder
braid
- This
is used to remove solder.
- To
use the braid, place it over the solder to be removed and heat it from
above with the iron. The solder will flow into the braid.
- Solder
braid is used to extract an electronic component that is soldered onto a
board.
- It
is also used to reduce the amount of solder on a connection.
- Prototype
board
- A
prototype board is used to assemble the circuit. The board shown is
from www.protostack.com, but Jameco Electronics also supplies
prototype boards.
- Prototype
boards have copper tracks or pads for connecting components.
- Steel
wool or fine sandpaper
- This
is used to clean connections prior to soldering.
- Solder
will not flow over a dirty connection.
- Crocodile
clips
- These can be used as heat sinks, if needed.
