Use lead free solder in servicing from the standpoint of antipollution for the global environment.
・ Be precautious about lead free solder. Sn-Ag-Cu (tin, silver and copper) will tend to splash when heated too high (approx. 600°C or higher).
・ Use lead free solder for the P.C.Board (specified on it as “PbF”) which uses lead free solder. (When you unavoidably use lead solder, use lead
・ solder after removing lead free solder. Or be sure to heat the lead free solder until it melts completely, before applying lead solder.)
・ After soldering to double layered P.C.Boards, check the component side for excess solder which may flow onto the opposite side.
For the P.C.Board which applies lead free solder, the symbol as shown in the figure below is printed or stamped on the surface
or the back of P.C.Board.
