Used ICs: MIP2H2, CXA3809M
The circuit boards used in these models have been processed using Lead Free Solder. The boards are identified by the LF logo located close to the board designation e.g. H1 etc [ see example ]. The servicing of these boards requires special precautions.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.
