[Click eStock] "NJET Expected to Emerge as a Glass Substrate Stock Leader with EHD Printing Technology"

On December 17, independent research firm ValueFinder analyzed that NJET is expected to emerge as a key player among glass substrate-related stocks, thanks to its EHD printing technology.

NJET, established in 2009 and listed on the KOSDAQ market in 2022, is a provider of EHD printing and coating solutions. EHD technology is a precision printing and coating technology that uses electricity to finely draw and spray liquid. This technology utilizes an electric field to delicately pull and spray droplets from outside the nozzle, enabling the implementation of finer line widths and uniform film thickness. As a result, it is known to be in high demand in high-precision manufacturing fields such as displays and semiconductor packaging. Based on EHD technology, NJET has commercialized both printing and spray methods, securing the technological capability to apply these solutions to packaging processes across various industries.

Lee Chungheon, a researcher at ValueFinder, stated, "In order to commercialize glass substrates, which are considered a game changer in semiconductors, major domestic companies such as Samsung, SK, and LG have recently begun to actively pursue related businesses." He added, "While improving chip performance is essential for managing data in the AI industry, there is a lack of advanced packaging technology, making glass substrates a proposed alternative."

He further explained, "However, the key to commercialization is solving the yield issue. The biggest current problem is yield reduction due to TGV micro-defects. When holes are drilled, fine cracks can occur, which may cause the substrate to break, resulting in a decline in overall substrate reliability, which is directly linked to costs." NJET has recently developed a high-precision inspection AI software capable of automatically detecting micro-defects down to 3μm in the glass substrate packaging process.

In November, NJET announced its plan to acquire the recycling division of EMR Co., Ltd. Products such as PCBs and glass substrates that cannot be repaired are typically discarded, but these parts contain significant amounts of metal, making them recyclable. While the company possesses facilities capable of extracting gold, silver, nickel, and other metals, it is understood that the decision to sell was made because it was unable to purchase expensive raw materials. Through this acquisition, NJET is expected to generate strategic synergy with its existing EHD-based packaging equipment business unit.

Researcher Lee added, "On December 11, NJET issued the first round of convertible bonds worth 6 billion KRW. The proceeds are expected to be used for research and development costs for the newly developed AI software and the advancement of existing EHD equipment, laying the groundwork for NJET to establish itself as a mid- to long-term player among glass substrate-related stocks."
