Health dangers associated with lead use are well-documented, and most countries have already begun the transition to lead-free soldering solutions because of these negative effects. Here’s what you need to know about working with lead-free solder.
Advances in soldering chemistry are slowly allowing lead-free solder to shed its reputation as an inferior alternative to lead-based solder. Adding tin, silver, copper and nickel in various amounts adds strength to lead-free solder and, in some cases, offers superior strength.
Lead-free solder also has less impact on the environment when used over the long term, as properly disposing of lead presents its own unique set of challenges. Lead-free alternatives are easier to dispose of when no longer needed, and they pose a much smaller risk to health.
It is important to note that the more pure lead-free solder is, the stronger and more reliable it is. This means that you should never mix it with lead-based solder, as this can lead to weakened joints. Also, lead-free solder does not require special soldering irons for use, especially when the application calls for switching soldering material.
