Detailed Steps of Stainless Steel Electrochemical Etching
Stainless Steel Electro Cleaning Line
- Process: Utilizes high-quality water to remove contaminants from stainless steel.
- Water Quality Recommendation: Use deionized water to prevent impurities.
Stainless Steel Electro Painting and Drying Line
- Temperature Control: Precise control is crucial for uniform paint application.
- Process Flow: Stainless steel is painted, then dried at controlled temperatures to ensure adhesion.
Exposure Line
- LED Exposure: Suitable for less complex patterns; works by exposing photoresist-coated stainless steel to UV light.
- LDI (Laser Direct Imaging): Ideal for high-precision patterns; uses laser beams for direct imaging.
- Work Flow:
- LED Exposure: Place the photoresist-coated steel under an LED light source.
- LDI Exposure: Use laser beams to expose the steel, adjusting parameters for pattern complexity.
Developing Line
- Post-Exposure: Develops the image after exposure by removing unexposed photoresist.
- Necessity: Developing reveals the pattern created during the exposure phase.
Stainless Steel Electrochemical Etching Line
- Process: Involves immersing the developed stainless steel into a copper chloride solution.
- Parameters:
- Temperature: Maintain between 40-50°C.
- Etchant Concentration: Typically 15-20% copper chloride.
- Experience Tips: Regularly monitor etchant strength and temperature for consistent results.
Stainless Steel Electro Stripping Line
- Details: Strips away residual photoresist and other unwanted materials post-etching.
- Procedure: Uses chemical baths or mechanical methods for cleaning.
