  • Page 161 HL-5030/5040/5050/5070N SERVICE MANUAL 5. Precautions for hand soldering operations 1) Soldering operations using lead-free solder are basically the same as those using tin- lead solder, however, due to the lead-free solder's characteristics of being difficult to melt, wet, and spread, as well as being hard, a soldering iron needs to be applied for a longer period of time than when soldering with conventional tin-lead solder.
  • Page 162 CHAPTER 4 DISASSEMBLY AND RE-ASSEMBLY 7) A localized ventilation system and gloves are required for soldering operations. Lead-free solder does not contain the toxic substance lead, however, inhalation of the fumes may adversely affect the health of workers. The silver contained in lead- free solder is also a toxic substance, though it is not as toxic as lead, and, therefore, a localized ventilation system and gloves are required for lead-free solder soldering operations, as required for those with conventional solder.
