🟢 Product Name: Solder Mask Ink - UV Photosensitive Green Ink
Packaging: 100g
⚫ Available Colors: Red, Blue, Green, Black, White, Yellow
💍 Description: This specialized UV photosensitive green ink serves as a protective solder mask for printed circuit boards (PCBs), essential for both prototyping and maintenance. It offers rapid curing capabilities, ensuring efficiency and durability. Designed specifically for screen printing, this ink provides exceptional performance, sealing the protected areas during the printing process (with the pad remaining ink-free) before being cured with UV light.
🔧 Features:
- Fast Curing: The ink cures quickly under ultraviolet light, enabling faster production cycles.
- Strong Adhesion: The ink boasts strong adhesion properties, ensuring longevity and reliability on circuit boards.
- Chemical Resistance: Provides excellent resistance to various solvents and chemicals, enhancing the durability of the solder mask.
- Insulation Properties: Offers impressive insulation resistance, making it suitable for high-performance electronics.
- Dielectric Strength: Demonstrates high dielectric strength of over 500V/mil, ensuring safety and performance in demanding applications.
🧩 Specifications:
- Viscosity: 200±50 PS at 25°C with good thixotropic properties
- Particle Size: Less than 15 microns
- Curing Conditions: Requires a 3000W UV lamp with a recommended irradiation distance of 10cm at a speed of 4-6m/min
- Adhesion: Achieves a score of 100/100, ensuring firm application
- Hardness: Exceeds 5H, providing a resilient coating
- Solder Resistance: Withstands temperatures of 260±5°C for up to 10 seconds, repeated three times
- Solvent Resistance: Resists degradation in trichloroethane after boiling for 2 minutes
- Insulation Resistance: Maintains levels above 1×1013 in a normal state, dropping to 1×1012 after 72 hours at 40°C and 95% RH
💥 Storage Recommendations: Store in a controlled environment at 22±2°C with a humidity level of 55±5% RH to maintain optimal performance.
Usage Notes:
- Stir well before use to ensure a uniform consistency.
- This ink should not be diluted.
- For DIY applications, sunlight exposure (ideally at 30 degrees Celsius for 5-10 minutes) can be utilized for curing.
- For cleaning screens, it is recommended to use 783 washing water.
