💡 What is the best way to use leaded solder with rosin flux for PCB assembly?

- Leaded solder with rosin flux provides reliable wetting on copper and tin-plated pads when you keep the iron around 350-370 C - For fine-pitch components, the 0.015 in diameter helps control solder deposition and reduces bridging - Use fresh flux-core solder and clean surfaces to achieve bright, sturdy joints after reflow
