Distinction Of Lead Free (PbF) Printed Circuit Board• Printed circuit boards (manufactured) using lead free solder will have a PbF stamp on the Printed Circuit board.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 solder 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/600°C).• If you must use Pb solder, please completely remove all of the Pb free solder on the pin or solder area before applying Pbsolder. If this is not practical, be sure to heat the Pb free solder until it melts, before applying Pb solder.12.2.
