【摘要】：硝酸蒸氣測試實質(zhì)是全面檢驗電鍍后端子金沉積層對其基材的防護能力,而防護能力的高低決定于金的沉積厚度和金沉積層的致密性。通過使用自主研發(fā)的鎳鍍液以及新的金鍍液,實現(xiàn)了基材的填平,提高了金沉積層的致密性。配合各段(主要是鍍金后)采取的防護措施,使端子在金膜厚度不超過32μm的情況下能夠通過2 h硝酸蒸汽測試,滿足了某跨國公司客戶提出的對于端子質(zhì)量的高要求。
[Abstract]:The essence of nitric acid vapor test is to check the protective ability of gold deposit layer on its substrate after electroplating, and the protection ability depends on the thickness of gold deposit and the density of gold deposit layer. By using the self-developed nickel bath and the new gold plating bath, the substrate was filled and the densification of the gold deposit was improved. With the protective measures adopted in each section (mainly after gold plating), the terminal can pass 2 h nitric acid steam test under the condition that the thickness of gold film is not more than 32 渭 m, which meets the high requirement for the terminal quality put forward by the customer of a multinational company.
