3 Crucial Things You Need to Know Before Soldering With Lead Free Materials

Lead FreeSoldering with lead-free solder presents special challenges that you should know about before getting started. Knowing these challenges can help make it more likely that you will get the results you want. Three of the top items you need to keep in mind to meet those challenges are outlined below.

1. Lead Free Means Higher Wetting Temperature

Lead free Kester solder requires a higher temperature than those that are lead based. With its tin/silver/copper combination, this temperature is 217 degrees. This solder is no clean, an important aspect of lead free soldering since the higher temperatures required can often lead to unwanted residue.

2. Stability of Components

Though there are other types of lead free solder that are made with other alloys - tin-copper in particular - they have a higher melting point. This means that their wetting time is longer and it needs to be maintained for longer periods of time in order to ensure the right flow. Using Kester flux that is VOC, as well as lead free, helps ensure the balance out the high temperatures required by lead free solder.Kester 63-0004-0971 971M VOC Free No-Clean Liquid Flux

3. Compatibility Issues

When working with lead-free solder, ensuring that materials are compatible is imperative.This compatibility ranges from the tips used to the materials being soldered. Tips that are specifically designed to be used in lead free applications also reduce the residue, giving the finished product a cleaner look.

Though working with lead-free solder can present challenges, they can be overcome with a few key adjustments. The benefits of a lead-free environment make the challenge of lead-free solder one to meet wholeheartedly.
