The standard configuration of oxygen sensor Ceramic PCB

In the 21st century, people have begun to pay attention to environmental issues. The most impressive thing is that global temperatures such as rising sea levels and the ozone layer are warming. For example, industrial cities in developed countries have long been infested by polluted gases, and the fog has turned into a haze. Travel and survival have had a certain impact.

Part of these polluting gases comes from more and more cars on the road. There has been an initiative before that an air pollution tax should be levied on automobile exhaust, because the main components of automobile exhaust pollution are hydrocarbons, nitrogen oxides, carbon monoxide, sulfur dioxide, lead compounds, benzopyrene, and solid particulate matter. After a detailed understanding of the exhaust gas composition, the role of the oxygen sensor is well explained. The oxygen sensor is an indispensable part of the automobile oxygen sensor. It mainly uses ceramic sensitive elements to detect the oxygen potential in the exhaust gas. It has a special chemical principle to calculate and obtain the data, and then determine whether the exhaust gas meets the standard according to the oxygen concentration in the data., The ultimate goal is to control the fuel injection nozzle.

Ceramic-sensitive components are very important for oxygen sensors. Because of direct contact with exhaust gas, much organic material PCBs are difficult to handle. The reason why ceramic PCBs are favored by manufacturers is mainly that their oxide layer does not contain organic components and will not easily Participate in chemical reactions, run well in harsh environments, and have long-term stable performance. In addition to this most valued feature, low energy consumption and stable electrical conductivity are also the advantages of ceramic PCB materials. What makes ceramic PCB truly a standard for automobile exhaust gas detection oxygen sensors is because of the improvement of domestic ceramic PCB technology, which effectively guarantees product quality.

For domestic manufacturers, most of the previous ceramic PCBs were imported from abroad, and the cost issue should not be underestimated. There are some practical concerns when using domestic ceramic PCBs. For example, the manufacturing technology of ceramic PCBs also has the problem of high hardness and brittleness in the early research in my country. It is possible when hitting hard objects or blowing with strong airflow. Make it fragmented. Therefore, LAM technology can be regarded as strong medicine for both the professional team that has solved the ceramic PCB upgrade technology and for the manufacturers who have been looking forward to the technology upgrade for a long time. The Silicon brand has been leading the technological progress in the ceramic PCB field, conforming to the development of the times, and providing high-standard, high-performance, low-energy ceramic PCB materials that meet the needs, not only in the field of sensors but also in other electronic industries. Attention and extensive use.
