The
first step is to apply a little solder to the pad on the PCB. Heat
the pad with the tip of the soldering iron at the same time touch
the end of solder wire to the heated area. The pad will get coated
with solder. |
|
|
Next,
place the SMD (we are using an IC as an example here) in its exact
position on the pads. Hold the SMD down with the tweezers and heat
the pad where you earlier put solder. The SMD will get anchored
on to the PCB by this.
|
|
|
|
|
Now,
solder all the pads one by one. Finally, the first pad that was
heated to anchor down the SMD needs to soldered properly.
Use
this method to solder all other SMDs as well.

A
magnifier with a stand is a useful aid to perform better while soldering. |

| Examine
all soldered joints with a powerful glass to ensure that all connections
are proper. |
