Study Notes
Preparing the Soldering Iron
- Position the soldering iron on its stand before connecting to power.
- Allow the soldering iron to heat up for several minutes until it reaches approximately 300°C.
- Clean the soldering iron tip by scraping off any residues.
- Coat the cleaned tip with a small amount of solder, ensuring proper heat conduction.
- Scrape the tip again after applying solder to maintain its cleanliness.
Soldering Technique
- Grip the soldering iron like a pen, near the base of the handle for better control.
- Place the heated soldering iron directly onto the joint that requires soldering.
- Introduce a small quantity of solder onto the joint while the iron is in contact.
- Withdraw the solder first, followed by the soldering iron, ensuring the joint remains still during the process.
- Examine the soldered joint carefully; a proper joint should have a shiny appearance and a volcano-like shape.
