摘要:
在连接器接触体的镀金过程中，深孔部位常产生黑孔现象，严重影响产品的合格率。针对这一问题，研究了不同工艺条件对深孔镀金层质量的影响。结果表明，振动频率升高时产品合格率先升后降，振动频率为20 kHz时合格率最高，达70.5%；随着镀液温度升高，黑孔数量先降低后升高，温度为35 ℃时合格率最高，达到100%。对振频和温度等工艺进行优化后完全消除了黑孔问题，产品质量得到提升。
Abstract:
During the gold plating process of electrical connectors, black holes often occur in the deep hole, which seriously affects the product’s qualified rate. In response to this issue, the influence of different process conditions on the quality of deep hole gold plating layer was studied. The experimental results show that as the vibration frequency increases, the rate of product qualification first increase and then decrease. The highest qualified rate of the coating is 70.5% when the vibration frequency is 20 kHz. As the temperature of the plating solution increases, the number of black holes first decrease and then increase. The highest qualified rate reaches 100% at the temperature of 35 ℃. After improving processes such as vibration frequency and temperature, the problem of black hole was completely eliminated, significantly improving product quality
