PCBs manufactured using lead free solder will have the PbF within a leaf Symbol
stamped on the back of PCB.
Caution
- Pb free solder has a higher melting point than standard solder. Typically the
melting point is 50 ~ 70 °F (30~40 °C) higher. Please use a high temperature
soldering iron and set it to 700 ± 20 °F (370 ± 10 °C).
- Pb free solder will tend to splash when heated too high (about 1100 °F or 600 °C).
If you must use Pb solder, please completely remove all of the Pb free solder on
the pins or solder area before applying Pb solder. If this is not practical, be sure
to heat the Pb free solder until it melts, before applying Pb solder.
- After applying PbF solder to double layered boards, please check the component
side for excess solder which may flow onto the opposite side. (see figure below)
Suggested Pb free solder
There are several kinds of Pb free solder available for purchase. This product uses
Sn+Ag+Cu (tin, silver, copper) solder. However, Sn+Cu (tin, copper), Sn+Zn+Bi (tin,
zinc, bismuth) solder can also be used.
