Copper erosion: The influence of metallurgy on copper dissolution: The rate of copper dissolution

2008
Lead-free solder alloys, particularly those with higher silver and lower copper contents, have been shown to react with the copper on circuit boards, dissolving the copper much more quickly than tin-lead solders. Rapid dissolution of copper into tin-rich alloys can create hidden defects and reliability issues, and as copper is washed off the PCB, the ...

Maximisation of extraction efficiencyin copper metallurgy

2016
Мідна виробництво складається з двох основних стадій: плавлення матеріалу і перетворення, що супроводжуються великими втратами міді. Окремі дослідження збільшення продуктивності, на цих двох стадіях не дали добрих результатів до теперішнього часу. Ця робота пропонує новий підхід до проблеми підвищення продуктивності виробництва міді.
