How to Use:

1. Preparation:
   • Add the entire contents of the sachet to 1 liter (1000 cc) of deionized water.
   • Stir continuously until the powder is completely dissolved to form a ready-to-work solution.
2. Surface Preparation:
   • Ensure the photoresist-coated substrate is clean and free of debris before application.
3. Application:
   • Apply the diluted developer solution by immersion, spray, or brush onto the substrate.
4. Development Time:
   • Monitor the developing process, which should take less than 1 minute, to achieve desired results without over-developing.
5. Rinsing:
   • After developing, rinse the substrate thoroughly with deionized water to remove any residual developer and unexposed photoresist.
6. Drying:
   • Allow the substrate to air-dry or use a lint-free cloth for gentle drying.

Safety Precautions:

• Personal Protective Equipment (PPE): Always wear gloves, safety goggles, and appropriate lab attire when handling chemicals.
• Ventilation: Ensure a well-ventilated workspace to avoid inhalation of any dust or vapors.
• Storage: Store sachets in a cool, dry place away from direct sunlight and moisture to maintain stability.
