The Benefits of Electrically Conductive Epoxies Versus Lead Soldering

Electrically conductive adhesive EP21TDCS is the ideal candidate to replace lead soldering for electrical connections and packaging for electronic components. This two component, silver filled adhesive is widely used for high performance bonding and sealing. It readily develops high bond strengths after curing that are remarkably adaptable to thermal cycling and resistant to chemicals. Master Bond EP21TDCS is serviceable over the exceptionally wide temperature range of 4K to +275°F enabling it to be used in cryogenic applications. It is also RoHS compliant.

Why Not Stick with Lead Soldering?

Although lead soldering has been widely used and relied upon for decades, the impressive development and growth of adhesive technology has brought to light the advantages of using polymer compounds for the joining of electronic components. There are two main concerns that can be avoided with the use of polymer compounds. These include:

  • Toxicity: Lead soldering results in harsh environmental impact. In fact, the impact is thought to be so bad that the European Union’s Restriction of Hazardous Substances Directive (RoHS) prohibits the use of lead in consumer electronics.
  • High temperatures: During the soldering process, the assembly is subjected to very high temperatures. Some temperature-sensitive components in the near vicinity might be damaged due to this high-temperature exposure. Lead solders can dissolve gold and form some brittle intermetallic compounds. In such cases, the mechanical strength of the joint is considerably reduced.
