• Quick Development Time: Develops photoresist in less than 1 minute, expediting your production process.

Yield Information:
One sachet of PR-3 powder will yield 0.5 liters of working developer solution, sufficient for developing a variety of photoresist substrates based on project requirements. It can effectively develop an area of up to 50 x 30 cm of 40 μm thick photosensitive films.

How to Use:

1. Preparation:
   • Add the entire contents of the sachet to half a liter (500 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: Work in a well-ventilated area to avoid inhalation of any dust or vapors.
• Storage: Keep sachets in a cool, dry place away from direct sunlight and moisture to maintain stability.

Common Applications:

• PCB Fabrication
• Microelectronics
• MEMS Development
• Various Laboratory Processes Involving Photoresist
