摘　　要：振动电镀机是一种新型的散件电镀设备,特别适用于针状、柱状微小零件及薄片状零件的电镀。振动电镀具有镀层厚度均匀、成品率高等优点。介绍了振动电镀的工作原理以及不锈钢弹簧针振动镀金工艺流程及各工序操作要点。性能测试表明,反复弯曲后镀层无脱落;通过(235±2)℃、3s焊锡实验,沾锡面积比大于95%;经过72h中性盐雾实验,镀层外观无明显变化。Vibration plater is a odd parts, specially suitable for new plating equipment for micro-parts with needle or pillar shape and flaked parts. Plating with vibration has the advantages of deposit with uniform thickness and high finished product rate, etc. The working mechanism of vibration plating and the process flow and main points of each procedure of gold plating with vibration for stainless steel spring needles were introduced. The performance tests show that the gold deposit doesn＇ t fall off after repeated bending; The area stained with tin accounts for over 95 % of the total area of the deposit after soldering test at （235 ± 2）℃ for 3 s ; No obvious appearance change of gold deposit is found after neutral salt spray test for 72 h.
