Explore Our Core Glass Technologies
YEKGLASS delivers high performance glass materials across five specialized product lines.
Glass Frit & Paste
YEK’s glass frit and paste are engineered for high integrity bonding between a wide range of materials. Designed for low temperature processing and tailored thermal expansion, our formulations support stress free, hermetic sealing in sensors, microelectronic packages, and optical modules-enabling durable protection against moisture and environmental stress.
Glass Wafer Processing
Our high purity glass wafers deliver excellent dimensional stability, ultra-low TTV, and smooth surface quality. Tailored for TGV (Through Glass Via), 2.5D/3D integration, or temporary carrier applications, these wafers enable high density interconnects, clean processing, and compatibility with next generation semiconductor packaging.
Precision Glass Processing
From ultra flat windows to multi functional substrates, YEK offers complete in-house processing including CNC machining, ultrasonic cleaning, and thin film coating. Our capabilities support demanding use cases in display manufacturing, semiconductor equipment, optical instrumentation, and aerospace components.
Phosphor in Glass
YEK’s PiG solution embeds phosphor particles in low-melting-point glass to achieve excellent heat dissipation and chemical stability. Designed for high power LED modules, automotive lighting, and horticultural systems, it offers consistent luminous flux and spectral integrity under harsh operating conditions.
Microfluidics Glass
Leveraging proprietary glass molding technology, YEK fabricates microfluidic chips with high aspect ratio channels, precise well depths, and exceptional glass clarity. These devices support ELISA, DNA amplification, sample prep, and other microfluidic workflows requiring chemical resistance and structural rigidity.
