Matusewitz MECetch line
This process replaces the brushing process in some areas. It brings far greater copper roughness and therefore it´s bigger surface. This treatment is suitable for application with dry resist, solder mask even for finishes pre-treatment. This technology is used also for copper surface treatment for flexi PCBs thanks to its minimal mechanical stress. Modern line software enables flexible program setting and simultaneously controls the automatic dosing based on continuous copper measurement.
