Ceramic Printed Circuit Boards (PCBs) by H-CELERITY PCB LIMITED

H-CELERITY PCB LIMITED specializes in the manufacture of high-quality Ceramic Printed Circuit Boards (PCBs), which are designed to meet the stringent demands of industries requiring exceptional thermal conductivity, electrical insulation, and mechanical stability. Our ceramic PCBs are engineered using state-of-the-art process technologies and materials to deliver unparalleled performance and reliability.

Key Technologies

Direct Bond Copper (DBC): This technology involves bonding a thin layer of copper directly onto a ceramic substrate using a high-temperature process. DBC is ideal for applications requiring high thermal conductivity and excellent electrical insulation, making it perfect for power electronics and high-power LED applications.
Direct Plated Copper (DPC): Utilizing photolithographic techniques, DPC allows for the precise deposition of copper layers on the ceramic substrate, enabling fine-line circuits and high-frequency performance. This technology is particularly useful in RF and microwave applications.
Active Metal Brazing (AMB): AMB utilizes brazing alloys to join copper to the ceramic substrate, allowing for the creation of complex structures and high-temperature applications. This technology is often used in aerospace and defense sectors.
High-Temperature Co-fired Ceramics (HTCC): HTCC involves printing conductive pastes (containing metals like tungsten or molybdenum) onto a green (unfired) ceramic tape, which is then co-fired at high temperatures. This results in a dense, reliable structure suitable for high-temperature environments.

Common Materials

Aluminum Oxide (Al₂O₃): Known for its good dielectric strength and thermal shock resistance, Al₂O₃ is a popular choice for general-purpose ceramic PCBs.
Aluminum Nitride (AlN): With higher thermal conductivity than Al₂O₃, AlN is often used in applications requiring better heat management, such as high-power electronics and LED lighting.

Alumina ceramic is a ceramic material with (AI2O3) as the main body, which is used in thick film integrated circuits.

Alumina ceramics have good conductivity, mechanical strength and high temperature resistance. Silicon nitride ceramics is an inorganic material that does not shrink when sintered with (Si3N4) as the main body. Silicon nitride is very strong, especially hot-pressed silicon nitride, which is one of the hardest substances in the world.

These two materials have certain commonalities. It is hard to say which one is better. It depends on the actual usage to choose the material.
