取代化学镍金的新型碱性化学银工艺具有以下特点:(1)镀层是纯银而不是酸性化学银的有机银,它在焊接时不会产生气泡;(2)它的焊接与邦定效果接近于化学镍金;(3)它的成本仅为化学镍金的25%-40%;(4)它易于除去铜和有机杂质,溶液可以长期使用;(5)使用专用的无氰退银和修复液使它易于返工和修复;(6)由于使用了特种的防变色剂,使它不需要除尘室、无硫手套和无硫包装纸.因此,新型的碱性化学银工艺是将来最具潜力替代化学镍金的表面涂(镀)工艺.

The new alkaline immersion silver process has following characteristics:1. Deposit is pure silver instead of organic silver of acid immersion silver process, so it does not produce void in welding 2. Its effect of welding and bonding is close to ENIG 3. The cost of alkaline immersion silver process is only 25%~40%of ENIG 4. It is easy to remove copper and organic impurity, so solution can be long-term use 5. It is easy rework and repair, because of new non-cyanide silver stripper and drop repairer are used 6. It does not require dust chamber, sulfur-free gloves and packaged paper, because of new antitarnish agent is used Thus new alkaline immersion silver process is the most viable alternative of ENIG in the future.
