Frequently Asked Questions
What is a microwave communication ceramic gold-plated board?
It is a high-frequency circuit substrate made of high-performance ceramic materials (such as alumina or aluminum nitride) with a high-purity gold layer deposited on the surface. It is widely used in microwave communication, radar, satellite systems, and antennas due to its excellent dielectric constant and temperature stability.
What are the main benefits of the gold plating on these ceramic substrates?
The surface gold plating treatment enhances oxidation resistance and electrical conductivity, provides strong corrosion resistance, and significantly improves the reliability of solder joints when applying gold wire bonding technology.
Can I customize the functional materials and surface treatments?
Yes, we provide customized services. Available functional materials include 99 alumina, aluminum nitride, and beryllium oxide. Surface treatment processes include nickel palladium plating, sputtered copper, and electroplated copper.
What are the thermal conductivity properties of these ceramic boards?
The thermal conductivity varies by material. Aluminum oxide offers a thermal conductivity of 24-28 W/(m·K), while aluminum nitride provides a much higher thermal conductivity of 170-230 W/(m·K) for demanding thermal management.
What are the recommended storage conditions for the gold-plated plates?
To maintain product quality and avoid oxidation, the plates should be stored in a controlled environment with a temperature of 5 ℃ to 35 ℃ and a relative humidity of ≤ 75% RH.
Why are these ceramic gold-plated boards used in aerospace and 5G base stations?
They are ideal because they support low-loss transmission of high-frequency millimeter-wave signals, help reduce equipment weight and size, and offer excellent temperature stability and radiation resistance required in harsh aerospace environments.
