摘要:
针对黄铜镀镍框架的镀锡层容易高温变色等问题，本文研发了一种由磷酸、复合有机酸、复合缓蚀剂及添加剂等成分构成的抗变色环保溶液。经过这种溶液处理后，镀锡零件表面形成了薄薄的透明致密保护膜，可以明显提高镀锡层在高温、高湿等环境中的抗变色能力、焊接性能和耐腐蚀性能等。测试结果表明，这种抗变色处理，可以满足铜合金镀锡产品的JESD22-A101-D标准，JESD22-B102E标准和J-STD-020E标准等技术要求。
Abstract:
Aiming at the problem that the tin-plated layer of the brass nickel-plated frame is prone to discoloration at high temperatures, an anti-discoloration and environmental protection solution composed of phosphoric acid, composite organic acid, composite corrosion inhibitor, and additives is developed in this paper. After this solution treatment, a thin, transparent and dense protective film is formed on the surface of tin-plated parts, which can significantly improve the anti-discoloration ability, solderability and corrosion resistance of the tin-plated layer in high temperature and high humidity environments. The test results show that this anti-tarnishing treatment can meet the technical requirements of JESD22-A101-D standard, JESD22-B102E standard and J-STD-020E standard of copper alloy tin-plated products.
