40W Ceramic Case

40W ceramic case is a high-reliability packaging solution tailored for high-power electronic components that require long-term continuous high-load operation-such as communication base station high-power RF power amplifier modules and industrial laser power modules-relying on advanced material combination and process technology to meet strict performance standards. As specified, product typically adopts direct copper bonding (DBC) or active metal brazing (AMB) processes, which bond alumina or silicon nitride ceramic substrates with metal frames to achieve high strength and high airtightness. This structural design gives 40W ceramic case two core advantages: an ultra-low thermal resistance of less than 1.5 K/W, ensuring efficient heat transfer, and excellent insulation performance with a breakdown voltage exceeding 15 kV, preventing electrical leakage in high-voltage scenarios.

In terms of airtightness, product meets the strict requirement of less than 10⁻⁸ Pa·m³/s, which is crucial for protecting internal components from moisture and pollutant intrusion-especially in communication base stations located in humid or dusty outdoor environments. When used in high-power RF power amplifier modules of communication base stations, 40W ceramic case efficiently transfers the large amount of heat generated by the amplifier during operation to external heat sinks, keeping the module's junction temperature within the safe range. This stable thermal management ensures that the amplifier does not experience performance attenuation due to overheating, even during 24/7 continuous operation.
