08-21 / 2019

励高精密模具有限公司是专业生产设计接触弹片、精密冲压件、非标冲压件等五金小元件。产品广泛应用于连接器、汽车电子、新能源、医疗电子、智能家居、二三极管及IC封装等行业。


接触弹片镀铜有两种方法:


一种是化学镀铜。化学镀铜广泛应用于各行各业,如:电子电器、五金工艺、工艺品、家具装饰........。化学镀铜稳定性较高,工作温度和溶液浓度适用范围较宽。铜层致密,有极佳的结合力。基本适用于所有金属及非金属表面镀铜。镀层厚度均匀,工艺设备简单、镀层性能良好。


一种是电镀铜,在PCB制造业中,电镀铜已经应用许多年了,印制板电镀铜溶液属酸性溶液,具有高酸低铜特点,有极好的分散能力和深镀能力 镀后的铜层有光泽性。铜层可以装饰五金接触弹片的表面,还可以起到抗腐蚀作用。
