Top Ceramic PCB Manufacturers in China: 6 Companies Compared

The main Chinese makers of ceramic circuit substrates and ceramic PCBs with public, checkable documentation are Ferrotec’s China power-substrate operations, Fujian Huaqing Electronic Material Technology, Bomin Electronics, Hebei Sinopack Electronic Technology, Chaozhou Three-Circle (Sanhuan, CCTC) and Guangdong Fenghua Advanced Technology. They are not interchangeable: the first three make metallized ceramic substrates such as DBC, AMB and DPC, Sinopack focuses on aluminum nitride substrates and ceramic packages, and Sanhuan and Fenghua are broader electronic-ceramics and materials groups. Choose by the part you need, then confirm the process, site and documents for your drawing.

Company information was checked against each company’s own product pages and stock-exchange disclosures in September 2026. This is a document review, not a factory audit or a test of their products.

How Was This List Chosen?

We included companies that are based in China, make ceramic substrates, metallized ceramic circuits or the materials for them, and publish their products and corporate identity in sources a buyer can check: their own product catalogues, stock-exchange filings or official exhibitor listings. We left out sites that only claim to be “ceramic PCB factories” without process or company detail, and we did not use capacity, yield or customer figures that the companies do not publish.

The list is ordered by how directly each company makes metallized ceramic circuit substrates, the item most ceramic PCB buyers are actually sourcing: power-substrate makers first, then AlN and package specialists, then the broader materials groups. It is not a ranking of quality or size.

Three terms come up throughout. DBC (direct bonded copper) bonds thick copper to alumina or AlN at high temperature; AMB (active metal brazing) brazes copper to AlN or silicon nitride and is used where thermal cycling is severe; DPC (direct plated copper) sputters and plates thinner copper for finer patterns. Our comparison of AMB and DBC explains the trade-offs.

Ferrotec (China Power-Substrate Operations)

Ferrotec makes power electronic substrates in China and publishes the widest range of copper-metallized ceramic processes on this list: DCB (its name for DBC), AMB, DPC and DAB, with operations in Dongtai, Shanghai and Sichuan. DAB uses aluminum rather than copper, so it is a separate product, not another name for DBC.

It fits power-module work for electric vehicles, rail, industrial drives and renewable energy, where the part is a metallized substrate rather than a multilayer circuit board. The ceramic, copper thickness and site depend on the product line, so ask which plant would build your part and request the data for that construction.

Huaqing Electronic

Fujian Huaqing Electronic Material Technology lists aluminum nitride and alumina ceramic substrates alongside DBC and AMB metallized products in its current catalogue. It is a substrate specialist rather than a general PCB maker.

It suits custom metallized ceramic substrates where you control the drawing. Older announcements mention HTCC as well; if you need it, ask for current product documentation rather than relying on the announcement.

Bomin Electronics

Bomin Electronics is a PCB manufacturer that has added a ceramic-substrate business. In a March 2026 announcement to the Shanghai exchange, it describes AMB and DPC ceramic-substrate operations in Shenzhen.

It is the most PCB-oriented company here, which helps if your team works in PCB terms and wants a supplier used to Gerber data. The announcement does not establish every ceramic and process combination, so confirm the ceramic type and whether DBC is offered before assuming it.

Sinopack

Hebei Sinopack Electronic Technology specializes in electronic ceramic packages and ceramic materials, and its product catalogue includes AlN ceramic substrates. It is listed in Shenzhen.

It is relevant when the part is an AlN substrate or a ceramic package rather than a patterned circuit. A package supplier’s drawing review and documents are built around housings, seals and plating, so check whether your quote covers a bare substrate, a metallized substrate or a package.

Sanhuan (CCTC)

Chaozhou Three-Circle (Group) is an electronic components and advanced materials group founded in 1970 and listed in Shenzhen since 2014. Its portfolio includes electronic ceramics and ceramic substrates among many other products.

Use it for material and substrate sourcing at scale. For a small custom metallized part, ask which business unit or channel handles it and whether it covers metallization, patterning and inspection.

Fenghua Advanced Technology

Guangdong Fenghua Advanced Technology is a Shenzhen-listed electronic components and materials group whose products include ceramic powders, precious-metal powders and electronic pastes. That makes it an upstream supplier to the ceramic circuit chain rather than a maker of patterned ceramic boards.

It belongs on the list as context for where Chinese ceramic circuit makers get materials; it is not a first stop for a ceramic PCB quote.

Which Type of Supplier Fits Your Project?

The one that makes the item on your drawing. Match the project to the supplier type first:

Material choice comes before supplier choice. Alumina (about 24 W/m·K) suits LED, sensor and insulation boards; AlN (about 170 W/m·K) suits high heat flux; silicon nitride suits power modules with heavy thermal cycling. Our ceramic PCB guide covers the materials in more depth.

How Do You Verify a Chinese Ceramic PCB Supplier?

By asking questions only a real maker of your part can answer, and checking the answers against documents. Four steps:

1. Name the deliverable. Ask whether the quote is for ceramic sheets, a metallized substrate, a patterned circuit board or a package, and which steps the supplier performs itself.
2. Name the process. Ceramic grade, metallization (DBC, AMB, DPC, thick film, HTCC, LTCC), copper thickness and surface finish, for your drawing.
3. Name the site. The legal entity and plant that will build your part, and the certificates for that site.
4. Ask for evidence. A sample from the same construction, a dimensional report, peel or adhesion results and, for power parts, thermal-cycling data at your profile.

A capable supplier will come back with questions about copper thickness, flatness, outline method, thermal path and assembly temperature. A reply that repeats “ceramic PCB” without any of these is a reason to look further. Our list of questions for evaluating a ceramic PCB manufacturer goes through them in detail.

Where QueenEMS Fits

QueenEMS is not part of the list above; we are the publisher of this guide. Our Shenzhen factory builds conventional rigid, flex and metal-core boards and, on the ceramic side, alumina, AlN and Si3N4 boards by DBC, DPC, AMB, HTCC or LTCC. The factory is IATF 16949, ISO 9001 and ISO 14001 certified, with UL certification as well. We have no minimum order quantity, so a prototype or a small batch of ceramic boards gets the same drawing review as a production order, with questions and quote assumptions sent back in English. Our ceramic PCB manufacturer page lists what we build.

Conclusion

Pick the supplier type from the part on your drawing, then verify process, site and samples before ordering. Contact us with your Gerber files, ceramic and copper specification and quantities if you would like a quote from us as well.

FAQ

Who are the top ceramic PCB manufacturers in China? Among companies with public documentation: Ferrotec’s China operations, Huaqing Electronic, Bomin Electronics, Sinopack, Sanhuan (CCTC) and Fenghua Advanced Technology, each covering a different part of the ceramic circuit supply chain.

What is the difference between a ceramic substrate and a ceramic PCB? A ceramic substrate can be a plain sheet or a metallized blank; a ceramic PCB has a patterned copper circuit, finish and outline made to your drawing.

Can large Chinese ceramic suppliers handle prototypes? Some can through sample programs, but many are set up for large supply contracts. Ask about minimum quantity, engineering contact and lead time before sending a small order.

Should I choose DBC or AMB? DBC is the established choice for alumina and AlN power substrates; AMB is chosen for silicon nitride and for applications with severe thermal cycling.

What should I send for a ceramic PCB quote? Gerber or ODB++ files, a drawing with ceramic type and thickness, copper thickness, surface finish, tolerances, quantity and delivery date.
