碱性蚀刻线路锯齿状现象分析与改善

Analysis and improvement of sawtooth status in alkaline etching lines

图形电镀板件蚀刻后线路边缘不规则凸起或凹陷,俗称"狗牙"现象,可能导致线路短路或开路,造成产品报废,特别是高频高速信号传输方面易造成信号干扰,影响信号准确性。文章通过对图电板件线路、电镀、蚀刻等生产流程中影响因素进行分析,以解决实际生产遇到的线路狗牙问题。

Graphic electroplating plate etching after the line edge irregular bulge or sag,commonly known as"dog tooth"phenomenon,may lead to short circuit or open circuit,resulting in product scrapping,especially when the highfrequency high-speed signal transmission is easy to cause signal interference,which affects signal accuracy.In this paper,the influence factors in the production process of graph and plate wiring,electroplating and etching are analyzed to solve the problem of line dog tooth encountered in actual production.
