Once this is accomplished, the part can be installed by holding it with
tweezers in contact with the “tinned” trace and re-heating the solder (see the
associated diagrams). Another commonly used technique is to glue the
surface mount components to the printed circuit board before soldering. The
procedure is to take a small amount of glue (usually with a pin or toothpick)
and “dab” the circuit board in the place where the component will be affixed.
Be careful not to apply too much glue as when the part is placed it may
“squash” the glue underneath the soldering tabs of the component. Carefully
place the part into position, and when the glue dries, solder the connection.
