Melstrip SE-100

Melstrip SE-100 是一种用于印刷电路板制造的铜种子层蚀刻液。可有效抑制蚀刻过程中因异种金属连接引起的电偶腐蚀。

◆特点
1.工作液为弱碱性液体。
2.有效抑制因异种金属连接引起的电偶腐蚀。
3.对铜蚀刻选择性高,对锡、镍等其他金属损伤小,适用于精细图形形成。
4.不含卤素:设备可使用不锈钢材质。

Suppression of the galvanic corrosion

Suppression of the galvanic corrosion
When copper is in contact with more noble metals, excess disolution of copper caused by electrochemical reaction so-called "galvanic corrosion", is observed during copper seed layer etching. Melstrip SE-100 is effective to suppress the galvanic corrosion with high selectivity to copper etching.

Relation between etching time and etched thickness

Relation between etching time and etched thickness
Etched copper thickness increases proportional to etching time.
