Ceramic PCBs are high-performance circuit boards that use ceramic materials such as alumina (Al₂O₃), aluminum nitride (AlN), and beryllium oxide (BeO) as insulating substrates. Compared to traditional FR-4 or metal-core PCBs, ceramic PCBs offer superior thermal conductivity, excellent electrical insulation, low thermal expansion coefficient (CTE), and outstanding mechanical strength, making them ideal for high-power, high-frequency, and high-temperature applications.
Introduction to DUV Purifier PCBs
Deep Ultraviolet (DUV) purifier PCBs are specialized circuit boards designed to power and control germicidal 200-280nm UV-C light systems, which are scientifically proven to destroy 99.9% of bacteria, viruses, and pathogens. These PCBs integrate high-efficiency drivers, sensors, and control circuits to ensure safe and effective disinfection in medical, industrial, and consumer applications.
Key Features of DUV Purifier PCBs
High-Voltage UV-C Driver Circuits – Precision-controlled power delivery to mercury-vapor or UVC LED lamps.
Advanced Thermal Management – Ceramic or metal-core substrates to dissipate heat from high-power UV emitters.
Safety & Monitoring Systems – Motion sensors, timers, and fail-safe shutoff to prevent human exposure.
EMI/RFI Shielding – Prevents interference with sensitive medical/communication equipment.
Corrosion-Resistant Materials – Protected against ozone (O₃) byproducts generated by UV-C wavelengths.
