A ceramic capacitor, also known as a ceramic dielectric capacitor or monolithic capacitor, is a type of capacitor that uses ceramic material as the dielectric and forms electrodes by coating metal films (usually silver) and sintering them at high temperatures.
As an essential electronic component in electronic devices, ceramic capacitors are widely used in various fields due to their high voltage resistance, low loss, small size, and good stability.
So, do you know what processes are involved in the manufacturing of ceramic capacitors? Let’s take a look at the manufacturing process of ceramic capacitors.
Processes used in the manufacturing of ceramic capacitors:
Pressing Process
The pressing process involves making ceramic materials into sheet-like forms. This is mainly done by using a press machine to compress ceramic powder into uniformly sized sheets.
The pressing process ensures the consistency of the size and thickness of the ceramic capacitors, improving production efficiency and reducing scrap rates and rework.
Sintering Process
The sintering process involves heating the pressed ceramic sheets to high temperatures, turning them into solid block-like materials.
This process aims to increase the density and hardness of the ceramic material, providing higher mechanical strength and improving the ceramic capacitor’s voltage resistance and dielectric constant.
Metallization Process
The metallization process involves bonding a metal layer onto the sintered ceramic body, which acts as the electrodes for the ceramic capacitor. These electrodes need to be tightly bonded with the ceramic dielectric to ensure the electrical and mechanical properties of the capacitor.
Through the ceramic capacitor manufacturing process, we can see that these techniques help improve the quality of the capacitors, making their performance more stable and reliable.
