PROCEDURE IN USING SOLDERING IRON.pptx

1. Procedure in Using a Soldering Iron

2. What is the purpose of a soldering iron in electronics? A soldering iron is used to melt solder, allowing electrical components to be connected together on a circuit board.

3. 1. Preparing the soldering iron a. Place the soldering iron on the stand before plugging it.

4. b. Wait a few minutes for the soldering iron to attain its operating temperature of about 400°C.

5. c. Wipe the tip of the soldering iron on the wet damp sponge

6. d. Melt a little solder (soldering lead – 60/40) on the tip of the iron.

7. Why? Improves Heat Transfer Prevents Oxidation Improves Solder Flow Enhances Tip Longevity better performance, cleaner joints, and increased tool longevity.

8. e. Wipe again the tip of the soldering iron on the wet damp sponge.

9. 2. Soldering technique a. Hold the soldering iron like a pen, near the base of the handle.

10. b. Touch the soldering iron onto the joint to be soldered. c. Apply a small amount of solder onto the joint.

11. d. Remove the solder, then the soldering iron, while keeping the joint in still position. e. Inspect the joint closely. It should look shiny and in a volcano shape.

12. Why is it important to clean the soldering iron tip? Cleaning the soldering iron tip ensures that old solder and contaminants do not affect the quality of the new solder joint, helping to make a clean and reliable connection.

13. 1. Multiple-Choice Question – Safety Precautions Before using a soldering iron, which of the following safety measures should be taken? A) Wear protective gloves and safety goggles. B) Touch the tip of the soldering iron to check if it’s hot. C) Work on a flammable surface like a cloth. D) Hold the soldering iron by the metal tip for better control.

14. 2. Scenario-Based Question – Proper Use A student is soldering a wire onto a circuit board but notices that the solder is not sticking properly. What should they do? A) Apply more solder without checking the issue. B) Ensure the soldering iron is at the right temperature and clean the tip. C) Use a plastic tool to press the solder down. D) Blow on the solder joint to cool it faster.
