SECTION 1 GENERAL
CAUTION
Lead Free Soldered Boards
example
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 to be taken as
outlined below.
Lead Free Solder material must be used to comply with environmental requirements of new solder joints. Lead Free Solder is available under
the following part numbers :
Partnumber Diameter Remarks
7-640-005-19 0.3mm 0.25Kg
7-640-005-20 0.4mm 0.50Kg
7-640-005-21 0.5mm 0.50Kg
7-640-005-22 0.6mm 0.25Kg
7-640-005-23 0.8mm 1.00Kg
7-640-005-24 1.0mm 1.00Kg
7-640-005-25 1.2mm 1.00Kg
7-640-005-26 1.6mm 1.00Kg
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.
