1. SERVICE PRECAUTIONS
1.1 NOTES ON SOLDERING
1.2 CAUTION
• For environmental protection, lead-free solder is used on the printed circuit boards mounted in this unit.
Be sure to use lead-free solder and a soldering iron that can meet specifications for use with lead-free solders for repairs
accompanied by reworking of soldering.
• Compared with conventional eutectic solders, lead-free solders have higher melting points, by approximately 40
°
C.
Therefore, for lead-free soldering, the tip temperature of a soldering iron must be set to around 373
°
C in general, although
the temperature depends on the heat capacity of the PC board on which reworking is required and the weight of the tip of
the soldering iron.
Do
N
OT use a soldering iron whose tip temperature cannot be controlled.
Compared with eutectic solders, lead-free solders have higher bond strengths but slower wetting times and higher melting
temperatures (hard to melt/easy to harden).
The following lead-free solders are available as service parts:
• Parts numbers of lead-free solder:
GYP1006 1.0 in dia.
GYP1007 0.6 in dia.
GYP100
8
0.3 in dia.
• Before removing the Power Amp Assy, it is neccessary to discharge C5721 and C5722.
