Product Overview

Concentrate Liquid Photoresist Developer D40 (120 mL) is a high-performance solution tailored for precision PCB photo fabrication. Designed for compatibility with negative-acting photoresist dry films and liquid inks, this developer ensures rapid, reliable results for intricate circuit board manufacturing and microelectronics applications.

Key Features

• Compatibility: Optimized for negative-acting photoresist dry films and liquid inks.

• Fast Development: Achieves full development in under 1 minute, accelerating production cycles.

• Extended Shelf Life: Indefinite storage stability when kept in a cool, dark environment.

• Cost-Efficient: A single 120 mL bottle yields up to 5.4 liters of working solution (diluted 1:18 with deionized water).

• Reusable Working Solution: Maximizes value by retaining effectiveness through multiple uses.

Yield & Dilution

• Working Solution Yield: 120 mL concentrate → 5.4 liters of developer.

• Coverage: Develops approximately 1.5 m² of 40-micron-thick photoresist dry film.

• Dilution Formula:
  Volume of D40 (mL) = 18 × Sump Size (L)
  Example: 18 mL D40 per 1 L deionized water.

Benefits

• Rapid Processing: Reduces downtime with sub-1-minute development.

• Economical: High dilution ratio lowers cost per application.

• Versatile: Suitable for immersion, spray, or manual application methods.
