The 2UUL UV Green Solder Mask is a specialized product used in the manufacturing and repair of printed circuit boards (PCBs). Here’s a breakdown of its features and characteristics:
Description:
**1. UV Green Solder Mask Composition:
- Type: UV-curable solder mask.
- Colour: Green, which is a common colour used in PCB manufacturing for its contrast with copper and ease of inspection.
**2. Application:
- Designed to be applied on PCB s to protect the copper traces from oxidation and prevent solder bridging between closely spaced pins during soldering.
- Applied as a liquid and then cured using ultraviolet (UV) light to form a durable, protective layer.
**3. Curability:
- Curing Method: UV light. The UV Green Solder Mask is initially a liquid that remains uncured until exposed to UV light, which hardens it into a solid, protective film.
- Cure Time: Typically, the curing process is fast and efficient under UV light, which speeds up production times.
**4. Needles for Application:
- Thin Needles: The UV Green Solder Mask package includes thin needles, which are used for precise application and dispensing of the UV Green Solder Mask. This allows for accurate placement and control, especially in fine-pitch areas or detailed PCB designs.
**5. Properties:
- Chemical Resistance: Resistant to chemicals used in PCB manufacturing processes.
- Mechanical Durability: Provides a tough, protective layer that can withstand the mechanical stresses of soldering and handling.
