2UUL PCB UV Green Curable Solder Mask with Thin Needles

The 2UUL PCB UV Green Curable 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. Solder Mask Composition:

• Type: UV-curable solder mask.
• Color: Green, which is a common color used in PCB manufacturing for its contrast with copper and ease of inspection.

**2. Application:

• Designed to be applied on PCBs 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 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 solder mask package includes thin needles, which are used for precise application and dispensing of the 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.
