Bison s-39 is a plastic protective sleeve commonly used to protect wires and cables. It is not a material for soldering, so it cannot directly solder wires or PCBs.
If you need to connect wires to the PCB, you can use appropriate soldering techniques such as thermocompression welding, ultrasonic welding, or laser welding, etc. These soldering techniques can effectively join wires with metal connectors or copper foil on the PCB to achieve reliable electrical connections.
Additionally, if you need to apply Bison s-39 to wires or cables, it is recommended to use it as a protective sheath or insulation material, not for soldering.
