Brushing and spraying with pumice or quartz powder produces excellent results in cleaning PCB surfaces and drilled holes and in creating microfine surface structures. This method is suitable for bore holes with larger diameters. For smaller drilled holes of 100 μm or less, brushing is more suitable.

Inline system for pumice or quartz powder spraying and brushing of drilled holes and surfaces

• Efficient filtration reduces consumption
• Optimized cascade rinsing with high pressure spray bars
• Reduced wear due to transport roller bearing rinse with labyrinth sealing
• No disposal costs for contaminated waste
