6. Soldering irons
When soldering is performed manually using lead-free solder, a soldering iron that has
little reduction in its temperature needs to be used. This refers to a soldering iron that
has a smaller degree of decrease in the temperature at the soldering iron's tip, such as
when the soldering iron is applied to the base metal or solder is supplied, and the
temperature is soon returned to the specified temperature.
With soldering operations using lead-free solder, the requirement for the temperature of
the soldering iron's tip is the same as that for conventional solder, however, the melting
point of lead-free solder is higher than that of conventional solder so productivity will
decrease with conventional soldering irons.
Some tool manufacturers sell soldering irons designed for lead-free solder and that can
maintain the productivity of the soldering operations.
The soldering irons used at BIL are model no. 941 manufactured by HAKKO and M6-
SIC-40 manufactured by BONKOTE. The prices of these soldering irons for use with
lead-free solder are three to four times higher than those for conventional soldering irons
with a temperature controller built in.
7. No mixing of different solders
When repairs are made on a PCB with an "LF" indication on it, lead-
free solder with the same metal composition, which is expressed by
the digit following "LF", must be used on a single PCB. For a PCB
with an "LF" indication on it, neither tin-lead solder nor lead-free solder
with a different metal composition must be used.
Compatible solder for each countries are listed below. Solders are freely available from each
manufacturer. Visit the web site below for more detail.
