  • Page 3: Precautions For Using Lead-Free Solder

    LC-42SV32B PRECAUTIONS FOR USING LEAD-FREE SOLDER ■ Using lead-free wire solder • When fixing the PWB soldered with the lead-free solder, apply lead-free wire solder. Repairing with conventional lead wire solder may cause damage or accident due to cracks. As the melting point of lead-free solder (Sn-Ag-Cu) is higher than the lead wire solder by 40 °C, we recommend you to use a dedicated soldering bit, if you are not familiar with how to obtain lead-free wire solder or soldering bit, contact our service station or service branch in your area.
