New Plant for High-Performance Insulating Ink Completed

Showa Denko K.K.
November 7, 2008

Nippon Polytech Corporation (NPC), a consolidated subsidiary of Showa Denko K.K. (SDK) located in Hachioji City, Tokyo, completed its new plant for high-performance electrical insulating ink for use in the manufacture of electronic parts based on the chip-on-film (COF) technology. These electronic parts—flexible components holding IC chips—are used to send electrical signals to liquid crystal display (LCD) panels for TVs, PCs and mobile phones to produce images. NPC will start up the new plant later this month.
The insulating ink, after being painted on the surface of the COF component, becomes an electrical insulating film that prevents short-circuit-induced malfunctioning.
As finer electronic circuits are needed to achieve higher image quality and lower cost, demand is growing for inks with higher electrical insulating property. NPC's ink drastically improves electrical insulation for the current 30-µm-pitch COF component. The ink can also be used for the latest production of 25-µm-pitch COF component, contributing to further improvement in image quality and longer life of LCD panels. NPC's high-performance insulating ink is made by using SDK's newly developed urethane-based thermoset resin.
Demand for LCD panel TVs is expected to continue growing in Japan due partly to the scheduled termination in July 2011 of analog broadcasting. Furthermore, world demand for LCD panel TVs is expected to increase steadily. Thus, demand for high-performance electrical insulating ink is forecast to grow substantially.
The Showa Denko Group will strengthen its IT chemicals business, covering photo-curing and thermoset resins for the production of semiconductors and displays, as one of the company's strategic businesses.
