Frequently Asked Questions

What are the advantages of ceramic PCBs?

Compared to standard FR4 PCBs, ceramic boards offer higher thermal conductivity, temperature resistance, electrical insulation, and ruggedness. These attributes suit them to harsh environments in aerospace, defense, and high-power applications.

What are the main ceramic PCB substrate materials?

Aluminum oxide and aluminum nitride are most common. Other options include glass/glass ceramic, beryllium oxide, and silicon carbide. Materials are chosen based on thermal, mechanical, and electrical requirements.

How is the manufacturing process different from FR4 PCBs?

Ceramic PCB fabrication involves pressed/fired layers, metallization, laser drilling, and lamination steps that differ from FR4 processing. Precise machining and drilling are required for microscale ceramic boards.

Why are ceramic PCBs more expensive than FR4?

The ceramic materials, fabrication techniques, and specialized processing increase costs substantially over standard glass-reinforced epoxy laminates. Lower production volumes also prevent economies of scale.

What thickness of ceramic PCBs can be produced?

Ceramic board thickness can range from ~0.25mm to over 2.0mm depending on layer count, material, and other requirements. Thinner constructions with more layers provide enhanced performance.
