From specialty ceramics,
to electronic substrates.
SIDAO Technology (Suzhou) Co., Ltd. is a high-tech enterprise integrating R&D, production and sales of specialty ceramic materials, with high-end aluminum nitride (AlN), ZTA, silicon nitride and alumina (Al₂O₃) electronic ceramic substrates as its core products. Main forming processes include tape casting and dry pressing.
The products are widely used in thick-film integrated circuits, semiconductor IGBTs, printers, LED lighting, new-energy vehicles, photovoltaics and energy storage, high-speed rail, aerospace and defense, and communication equipment — a new foundational material defined by high technical content, high added value and high entry barriers.
As international trade barriers intensify, domestically-made electronic ceramic substrates have clear room to grow. Leveraging tape casting's strength in high-volume industrial production, SIDAO targets insulation and heat-dissipation scenarios across electronic devices — built to fill a domestic gap.
