Ceramic PCB

Hitech Circuits: Your Ceramic PCB Partner

Hitech Circuits Co., Limited offers ceramic PCB and Ceramic Substrate PCB for your printed circuit board’s needs.

Many users of printed circuit boards find ceramic PCBs advantageous over traditional boards of other materials. This is because they provide suitable substrates for electronic circuits with high thermal conductivity and a low expansion coefficient (CTE). The multilayer ceramic PCB is extremely versatile and can replace a complete traditional printed circuit board with a less complex design and increased performance. You can use them for high-power circuits, chip-on-board modules, proximity sensors, and more.

We provide specialized ceramic printed circuit board (PCB) solutions for companies needing high-reliability boards. With over 10 years of experience designing and fabricating ceramic substrates, we are an industry-leading supplier in China committed to quality, service, and technical expertise.

What are Ceramic PCBs?

Ceramic printed circuit boards (PCBs) provide a substrate made of ceramic material rather than the traditional fiberglass for the circuits. Common ceramic materials include aluminum oxide, aluminum nitride, beryllium oxide, and silicon carbide. Ceramic PCBs offer higher heat resistance, superior thermal conductivity, lower expansion coefficient, better high-frequency performance, and smaller package sizes than traditional PCBs.

Benefits of Using Our Ceramic PCBs and Ceramic Substrate PCB!

Several key benefits make Ceramic Substrate PCB and ceramic PCBs an advantageous choice:  

• Higher Operating Temperatures - Can withstand temperatures exceeding 350°C.
• Enhanced Thermal Properties - Aluminum nitride boards provide thermal conductivity exceeding 150W/mK.
• Lower Expansion Coefficient - More stable performance across temperature changes.
• Compact Form Factor - Allows greater component density and miniaturization.
• Superior High-Frequency Performance - Low dielectric loss for high-frequency operation.
• Hermetic Packaging - Prevents moisture absorption issues.
• Lower System Costs - Simpler designs can reduce testing/assembly costs.Benefits of Using Our Ceramic PCBs and Ceramic Substrate PCB!

With their exceptional thermal conductivity, electrical insulation properties, and high heat and corrosion resistance, ceramic PCBs outperform conventional PCBs in demanding applications.
