The "Glass Core Substrate" in semiconductor advanced packaging relies on TGV (Through-Glass Via) technology combined with copper metallization for redistribution layers. It replaces the core layer of traditional ABF organic substrates with glass, eliminating warpage in large AI chips at elevated temperatures while pushing line width and pitch down to the micrometer scale.

Tin bronze is a core industrial copper-based alloy, widely used in machinery, marine, hydraulic, and precision electronics applications thanks to its excellent wear resistance, corrosion resistance, high strength, and good castability. It is commonly used to manufacture critical wear- and corrosion-resistant components such as bearings, bushings, pump and valve parts, marine fittings, and precision elastic elements — serving as a fundamental material for the reliable operation of high-end equipment.

Laser Metal Deposition (LDM) technology uses metal powder as feedstock, building up components layer by layer through a high-power laser to achieve near-net-shape forming of TC11 titanium alloy parts — without the need for large forging dies. This process offers high material utilization and short production cycles. As a high-temperature titanium alloy designed for long-term service at 500 °C, TC11 is widely used in critical load-bearing components such as aero-engine blades and compressor discs.
