How to solder in electronics Material: - Soldering Iron (30/40 Watts) - Solder (electrical, flux (rosin) core, lead-free) - Tip cleaner (steel wool or sponge) - Iron stand - Desoldering pump / Wick - Flux pen - Cutting pliers - Fine sand paper - Wire stripper - Helping hand Caution: - Do not burn yourself - Avoid breathing the fumes directly. It’s good to have a fan blowing on you. o Lead-free solder is always safer to use. - Do not overheat the components. A good solder joint is done in 4 seconds. o Let cool and start over if it doesn’t solder smoothly. Preparation: 1. Allow 10 minutes for the iron to heat up. 2. Clean tip by poking the steel wool until it’s shiny. 3. Apply flux on the parts (if necessary). This is better when the metals are dirty or oxidized. 4. Position the parts as needed. You have to be ready before you tin the tip. 5. Tin the tip - Add a little bit of solder on the tip. It’s done only when ready to solder. This helps conduct heat to the parts. Prepare the parts. Apply a light pressure on the BOTH parts with the TINNED tip. Approach the solder. As soon as you see the tin spread on both parts, apply pressure on the solder on the OPPOSITE side. Do not move the iron. You can move the solder. Let the solder melt around the parts. As soon as the solder is applied, quickly remove the iron and the solder. A good solder joint has a smooth texture and is very shiny. If not, remove the solder and start over. Cut off the extra wire or terminals after you’re done, they help absorb the heat and protect the components from overheating. Avoid applying too much solder as it creates extra resistance and can cause other issues.
