Manufacturing Process

The manufacturing process of the SMD 2538 involves several steps, including material preparation, die forming, lamination, and packaging. The ceramic material used for the dielectric is mixed with other components to form a paste, which is then applied to a substrate. The substrate is then baked to remove any moisture and ensure proper curing of the ceramic material. After the dielectric layer is formed, the capacitors are etched and trimmed to the desired size. The terminals are then attached to the capacitors, and the entire assembly is coated with a protective layer to prevent damage during transportation and assembly. Finally, the capacitors are packaged in a leadless, surface mount package and tested for quality assurance.
