The cyanide copper bath ZF 291 is a high performance electrolyte for the deposition of bright, smooth and fine crystalline copper layers. The electrolyte is often used as an under coat before further electroplating processes. It is suitable for frame and barrel plating.
ZF 290 is a newly developed bright copper process. The coating produced during this process features excellent throwing power and metal distribution. In many cases the exposure time can be shortened significantly due to extremely high leveling. The electrolyte is often used as an under coat before further electroplating processes. The copper layers are fine-grained […]
