UV-LED Curable Conductive Ink for Printed Electronics & PCB Marking

The UV-LED Ink for character marking on PCB has several key technical specifications and performance features:

Color and Shelf Life: The conductive ink for pcb is white in color and has a shelf life of 12 months.

Packaging and Print Head: It comes in 1KG packaging and is designed to be used with an industrial print head.

Material Compatibility: It is specifically formulated for use on PCB boards with solder mask.

Technical Parameters:

Viscosity: 20-40 mPa·s (industrial head)

Surface Tension: 20-30 mN/m

Printing Conditions:

Temperature: 20-30°C

Humidity: 40-80%

Performance Tests:

Adhesion Test: After baking in the oven at 150°C for 50 minutes, the adhesion grade is 0 (best possible result).

Yellowing Resistance: When soaked in a solder pot at 280-290°C, there is no yellowing.

Printing Fluency Test: In all tested scenarios (printing 2, 4, and 10 plates), there were no nozzle missing issues before or after printing.

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 conductive inkjet 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 conductive inkjet 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 conductive ink for inkjet 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.
