SERVICE PRECAUTIONS 1.1 NOTES ON SOLDERING 1.2 NOTES ON REPLACING 1.3 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 oC. Therefore, for lead-free soldering, the tip temperature of a soldering iron must be set to around 373 oC 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 NOT 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. GYP1008 0.3 in dia. The part listed below is difficult to replace as a discrete component part. When the part listed in the table is defective, replace whole Assy.
