How is the UV-LED Ink for character marking on PCB applied, and what safety guidelines should be followed?

The UV-LED Ink for character marking on PCB is applied as follows, with specific safety guidelines to ensure proper usage:

Application:

Recommended Environment: The ink should be placed in a constant temperature room and loaded into the printer until its temperature is suitable for printing.

Storage Condition: Store the ink in a black, airtight container in a clean place with a temperature range of 10-40°C and humidity between 40-85%, avoiding light, heat, and steam.

Usage: It is ideal for marking characters on PCB boards, providing clear and durable white markings with excellent adhesion and hardness on solder masks.

Safety Guidelines:

Handling: Avoid contact of uncured ink with skin. If contact occurs, wipe with a cloth or tissue and then wash with soap.

Medical Attention: If any skin allergies occur, seek medical attention promptly. Refer to the Material Safety Data Sheet (MSDS) for detailed information on the product's main components.

Storage After Opening: Keep the ink sealed after opening and store it in a cool place away from direct sunlight. Use the ink within two weeks of opening to maintain its quality.
