In-Depth Review TG4G Review ·2026-06-25 · For reference only

Basic Website Info

esubstrate.com is the official website of Shanghai Kaiqi Technology (including Anhui Kaiqi Technology). This company is a Chinese manufacturer focused on R&D and production of AMB copper-clad ceramic substrates, inheriting the technical experience of China's earliest team that developed mass production of AMB copper-clad ceramics. It mainly offers metallization products for various ceramic substrates, and supplies to high-end manufacturing fields such as power semiconductors and new energy.

Core Business and Highlights

Kaiqi Technology masters the full range of high, medium and low temperature AMB brazing technologies. It can provide AMB copper-clad substrates with multiple types of base materials including alumina, aluminum nitride, and silicon nitride. It also offers custom ceramic aluminum-clad substrates and thick-film ceramic circuit boards. It can achieve copper cladding up to 2.5mm thick, to meet the requirements of high-current applications. The company currently holds 19 related patents, has an existing annual production capacity of 6,650 square meters, and is expanding capacity to 100,000 square meters, which will greatly increase its supply capability in the future.

Pros, Cons, and Suitable Users

The official website only serves as an entry point for corporate presentation and business contact. Its advantages are: rooted in local technical accumulation, products adapted to multiple high-end niche fields, independent and controllable core technology, and support for customized requirements. The disadvantages are: the website has very basic functionality, and does not disclose core business information such as product specifications and pricing, so customers face a high threshold to obtain necessary information. This company is suitable for domestic power semiconductor packaging manufacturers, new energy power battery/energy storage manufacturers, and high-end communication device manufacturers to connect with as a local supplier.

Accessibility in China

The website has completed ICP filing, so it can be accessed directly and normally within mainland China. It supports multiple contact methods including QQ, phone and email, making communication very convenient.
