How to Solder with a Soldering Iron
You will need a soldering iron, solder wire, solder paste, solder parts, diagonal pliers, printed circuit board 1. Plug in the soldering iron to preheat. 2. Adjust the pins of the capacitor and insert it into the printed circuit board. 3. Apply a small amount of solder paste to the contact between the capacitor pin and the circuit board. Tip: It is also possible to apply no solder paste. 4. Press the soldering iron head of the preheated electric soldering iron on the contact between the pin and the circuit board for a moment to raise the local temperature to the melting point of the tin wire. Send the solder wire to the contact between the pin and the tip of the soldering iron, remove the solder wire when the amount of solder is appropriate, and move the soldering iron along the component pins to form a round solder joint. 5. Use diagonal pliers to cut off the excess pins, and the soldering operation is completed. Tip: The dwell time between each soldering step and the correctness of the operation have a great influence on the soldering quality, which needs to be gradually mastered in practice. Do you know? Generally, copper, gold, silver, alloys and nickel have good weldability, while aluminum, cast iron and stainless steel have poor weldability.
