"Eco-Solder"…Environmentally Friendly Lead-Free Solder |
Solder has a history of 5,000 years, and Sn-Pb solder, which consists of tin and lead, has played a fundamental role in this history. In recent years, however, groundwater contamination by lead has become a problem, and various regulations have been enacted to eliminate lead as an environmentally hazardous substance. Recognizing that environmental protection in the 21st century is a social mission, Senju Metal has conducted intensive research and developed "Eco Solder", a lead-free solder.
Senju Metal has developed the "Eco Solder", a lead-free solder, based on its diligent research and development. Senju Metal is able to pluralistically respond to the introduction of lead-free solder and in-line mounting in a variety of ways, as well as provide the most advanced
" Eco Soldering Solution™ " by building a comprehensive technological base and support system from various perspectives.
