1. SERVICE PRECAUTIONS
1.1 NOTES ON SOLDERING
• F or environmental protection, lead- f ree solder is used on the printed circuit boards mounted in this unit.
Be sure to use lead- f ree solder and a soldering iron that can meet speci f ications f or use with lead- f ree solders f or repairs
accompanied by reworking o f soldering.
• Compared with conventional eutectic solders, lead- f ree solders have higher melting points, by approximately 40 º C.
There f ore, f or lead- f ree soldering, the tip temperature o f a soldering iron must be set to around 373 º C in general, although
the temperature depends on the heat capacity o f the PC board on which reworking is required and the weight o f the tip o f
the soldering iron.
Do N OT use a soldering iron whose tip temperature cannot be controlled.
Compared with eutectic solders, lead- f ree solders have higher bond strengths but slower wetting times and higher melting
temperatures (hard to melt/easy to harden).
The f ollowing lead- f ree solders are available as service parts :
• Parts numbers o f lead- f ree solder :
