CHAPTER 4 DISASSEMBLY AND RE-ASSEMBLY 7) A localized ventilation system and gloves are required for soldering operations. Lead-free solder does not contain the toxic substance lead, however, inhalation of the fumes may adversely affect the health of workers. The silver contained in leadfree solder is also a toxic substance, though it is not as toxic as lead, and, therefore, a localized ventilation system and gloves are required for lead-free solder soldering operations, as required for those with conventional solder. 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 M6SIC-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, leadfree 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.

Lead-free solder does not contain the toxic substance lead, however, inhalation of

The silver contained in lead-
free solder is also a toxic substance, though it is not as toxic as lead, and, therefore,
a localized ventilation system and gloves are required for lead-free solder soldering
operations, as required for those with conventional solder.

This refers to a soldering iron that

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.
