Material Properties: Alumina, also known as aluminum oxide (Al₂O₃), boasts exceptional properties. It combines high electrical insulation, excellent thermal conductivity, and impressive mechanical strength. These attributes make it ideal for electronic applications.
Surface Finish: Alumina substrates undergo meticulous surface treatment to achieve precise grain size and smoothness. This attention to detail enhances fine-line resolution, spacing, and overall yields during thin-film processes.
Applications and Advantages
Hybrid Integrated Circuits (HICs): Alumina substrates serve as the foundation for HICs. These circuits combine both thick-film and thin-film technologies, allowing for compact designs and efficient signal processing.
Surface Mount Devices (SMDs): Alumina substrates support SMDs, such as resistors, capacitors, and inductors. Their durability ensures reliable soldering and long-term stability.
Sensors and Detectors: Alumina substrates find applications in sensors, where precision and sensitivity are critical. Whether it’s temperature sensors or gas detectors, alumina provides a stable platform.
Thick-Film Electronics: Alumina is the material of choice for thick-film substrates. These substrates accommodate small-geometry, high-resistance circuitry. They minimize resistivity variation and maximize adhesion over time.
Design Considerations
Thickness: Alumina substrates come in various thicknesses, typically ranging from 0.381 mm to 2.54 mm. Common thicknesses fall between 0.635 mm and 1.016 mm.
Standard Sizes: CoorsTek offers standard sizes, including 114.3 x 114.3 mm, 139.7 x 165.2 mm, and 127.0 x 177.8 mm. Custom sizes are available upon request.
Edge Finishing: CoorsTek provides edge finishing treatments, ensuring smooth edges for ease of handling and assembly.
Conclusion
Alumina ceramic substrates silently empower our electronic devices, enabling seamless communication, efficient energy conversion, and advanced sensing capabilities. Next time you hold a smartphone or interact with a smart sensor, remember that alumina is the unsung hero behind the scenes.
