Solder mask Ink

The solder mask ink has the characteristics of high resolution and low exposure energy, good insulation resistance and high temperature resistance and resistance to gold/chemical tin, with the processing capability of SMT parts, this series of products described in the following table.

Marking Ink

The Marking ink has good printability in operation and is not easy to dry. It has good three-dimensional characters, high whiteness, good yellowing resistance, heat resistance, and acid and alkali resistance. This series of products are described below.

Legend Ink

The legend inks have the advantage of large unit area, low exposure energy and high resolution, and good resistance to etching, making it easier to form lines. This series of products is described in the table below.
