25、ntal 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 solder

26、s, 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 w

27、eight 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 so
