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. For more information on the use of Lead Free Solder, please refer to http://www.sony-training.com KDL-32BX320/32BX321/32BX420/32BX421/40BX420/40BX421/46BX420/46BX421...
