Tokyo - Nippon Polytech Corp. (NPC), a subsidiary of Showa Denko K.K. (SDK) of Hachioji City, Tokyo, has built new plant to make high-performance electrical insulating ink, the company announced 7 Nov. NPC said it will start up the new plant later in November.
The ink is used in making electronic parts based on chip-on-film (COF) technology. Demand for this technology continues to grow globally, since the COF approach is used in LCD panels in all types of electronic displays, including HD TV sets, where demand is expanding as the move from analogue to digital technology continues, SDK indicated.
The insulating ink is made using SDK's newly developed urethane-based thermoset resin, said the group.
The ink is used in electronic COF parts, which are flexible components holding integrated circuit chips. These are used to send electrical signals to liquid crystal display (LCD) panels for TVs, PCs and mobile phones, to produce images, NPC explained.
The insulating ink is painted on the surface of the COF component to become an electrical insulating film that prevents short-circuit-induced malfunctioning, according to NPC. "As finer electronic circuits are needed to achieve higher image quality and lower cost, demand is growing for inks with higher electrical insulating property," said NPC.
NPC claims its 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 components, contributing to further improvement in image quality and longer life of LCD panels, said the SDK subsidiary.
Acording to NCP, demand for LCD panel TVs is expected to continue growing in Japan, due partly to the scheduled termination in July 2011 of analogue broadcasting, a phase-out that is happening in Europe as well. As a result, world demand for LCD panel TVs is expected to increase steadily, and consequently, "demand for high-performance electrical insulating ink is forecast to grow substantially," the Japanese group said.
Showa Denko Group said its IT chemicals business, covering photo-curing and thermoset resins for the production of semiconductors and displays, is one of its strategic businesses, and it intends to continue strengthening this activity.
