Product scope of application
Microwave communication ceramic gold-plated board refers to a high-frequency circuit substrate made of microwave ceramic materials. It is usually made by precision machining high-performance ceramic substrates such as alumina and aluminum nitride, and depositing a layer of high-purity gold on their surface through processes such as sputtering and electroplating. Microwave ceramic materials have excellent characteristics such as high dielectric constant, high quality factor, and good temperature stability, and are therefore widely used in high-frequency circuit fields such as microwave communication, radar, satellite communication, and antennas. The dielectric constant of microwave ceramic substrates is usually between 5 and 15, with a quality factor between 10000 and 100000. They have low dielectric loss and good frequency stability, making them suitable for the production of high-frequency circuits. As a key core material in the field of microwave and radio frequency, it is necessary to strictly control parameters such as plating solution composition and current density to ensure uniform coating thickness and avoid increased signal transmission loss. Especially in the aerospace industry, which is sensitive to material weight, it is necessary to optimize the thickness of the gold plating layer to reduce the overall weight.
