It is strongly recommended to use Lead Free Solder material in order to guarantee optimal quality of new solder joints. Lead Free Solder is
available under the following part numbers :
available under the following part numbers :
Due to the higher melting point of Lead Free Solder the soldering iron tip temperature needs to be set to 370 degrees centigrade. This
requires soldering equipment capable of accurate temperature control coupled with a good heat recovery characteristics.
