Ceramic PCB boards are a specialized type of board with excellent thermal conductivity, insulation, and a high dielectric constant, making them ideal for applications requiring heat dissipation. In comparison to regular PCB boards, ceramic PCB boards have several distinct advantages:
1、The materials used are different: ceramic PCB boards use inorganic materials, with the core material usually being aluminium trioxide or aluminium nitride; while ordinary PCB boards use organic materials, commonly FR4 glass fiber boards. Ceramic PCB boards are fragile and cannot be multi-layered, whereas ordinary PCB boards can be multi-layered.
2、Different performances and applications: ceramic PCB boards are mainly utilized in industries with high heat dissipation requirements, such as high-power LED lighting, high-power modules, high-frequency communications, rail power supply, and other fields. On the other hand, ordinary PCB boards are more versatile and are predominantly used in civilian commercial products.
1、Different materials: Ceramic PCB boards are mainly made using aluminum oxide or aluminum nitride, while high-frequency boards are typically constructed from materials such as Rogers, Arlon, PTFE, and others that have a low dielectric constant and high-frequency communication speeds.
2、Different applications: Ceramic PCB boards find widespread use in applications such as refrigeration chips, high-power modules, automotive electronics, and other fields where heat dissipation is crucial. High-frequency boards, on the other hand, are primarily utilized in high-frequency communications, aerospace, high-end consumer electronics, and similar industries.
3、Combined applications: In certain high-frequency communication scenarios, where efficient heat dissipation is essential, a combination of ceramic PCB boards and high-frequency boards is often necessary. This results in the production of high-frequency ceramic PCB boards.
1、Inspect ceramic substrate quality parameters: Ensure that the ceramic substrate selected offers chemical stability (including high-temperature resistance and resistance to strong acids and alkalis), as well as high thermal conductivity. Consult product specifications for detailed information on these quality parameters.
2、Examine the fine craftsmanship of the ceramic substrate: High-quality ceramic substrates must meet strict requirements for the spacing between electronic components, bonding tightness, and flatness. The overall appearance, including flatness and edge quality, also reflects the processing quality.
3、Conduct a trial: Take advantage of the thermal conductivity of the ceramic substrate by allowing it to operate for a period before cutting off power. Measure the temperature and current flow of the circuit. If the temperature rises excessively, it indicates poor thermal conductivity and low-quality ceramic substrates.
4、Research information from ceramic substrate manufacturers: Choose manufacturers with a reputable track record and appropriate qualifications, as this indicates adherence to formal production processes and quality material selection. Investigate the reputation and user feedback of the ceramic substrate brand as this can provide insight into the quality of the product.
