What type of solder is best for electronics?

rosin core solderFor electronics soldering, the most commonly used type is lead-free rosin core solder. This type of solder is usually made up of a Tin/Copper alloy. You can also use leaded 60/40 (60% tin, 40% lead) rosin core solder but it’s becoming less popular due to health concerns.

What happens if you leave a soldering iron on?

Power up soldering iron with new tip without immediately tinning the tip with solder as it is heating up.
