川裕 CHUNG YU INK

The ink is developed for various rigid and flexible boards, providing highly reliable products.

Solder mask inks include UV curing, thermal curing, traditional mask and maskless exposure and development types. The ink composition is halogen-free and complies with EU RoHS standards. It is suitable for processes such as chemical gold, chemical silver, OSP, lead-free tin spraying, pure tin plating or electroplating gold. It also has heat-resistant, thermally conductive, non-discoloring, and highly reflective solder mask ink, making it suitable for LED products. In addition, we provide customized products for plugging, metallic gloss, spraying, dry film type solder mask inks, as well as low dielectric (low Dk) and low loss (low Df) solder mask inks used in high-frequency and high-speed boards, or various types of board insulation inks.

Circuit inks include UV curing, heat curing and exposure developing types, and are easy to remove. It has screen printing, spraying, inkjet and roll coating types, suitable for etching copper, steel or ITO, etc., to make fine lines or patterns. For selective chemical processes, we also provide thermal curing or exposure developing inks.

The character inks include UV-hardening and thermal-hardening types, and are available in screen printing and inkjet types. The fonts are clear, three-dimensional, and have high hiding power. The patterns have high resolution and are heat-resistant and solder-resistant. The gloss is controllable, and the colors are bright and not easy to discolor.

CHUNG YU MARK INK is suitable for various PCB circuit boards. It has excellent anti-color change ability and can prevent text from changing color.
