Soldering

Soldering is the process of making permanent electrical connections between components using solder and a soldering iron. In embedded and robotics projects you use soldering to connect headers to microcontroller boards, attach wires to sensors, and build reliable prototypes on perfboard or PCBs. Good solder joints are mechanically strong, electrically reliable, and safe to work with.

For this product, you describe how you applied soldering in your project, which joints and assemblies you made, and how you ensured safety and quality.

Soldering in Embedded & Robotics Projects

Typical soldering tasks in this profile include:

• Soldering pin headers onto development boards (for example ESP32 boards)
• Soldering wires to sensors, buttons, or connectors
• Building small circuits on perfboard or prototype PCBs
• Repairing loose or broken connections

You plan your soldering work so that your hardware is robust enough for testing, transport, and long-term use.

Quality indicators

When assessing this product, the following quality indicators will be considered:

• The soldering work is appropriate for the project (for example headers, wires, or connectors were soldered where needed).
• It is clear which components and connections were soldered and why soldering was necessary.
• The solder joints are functional and reliable (no shorts/bridges, no cold joints, solid mechanical connection).
• The assembly is safe and neat (strain relief where needed, no exposed conductors that can short, tidy wiring).
• Safety was taken into account during the work (ventilation, careful handling of hot tools, organised workspace).
• There is evidence of the soldering work (for example photos of the assembled hardware and close-ups of key joints).
