Metallized Large Ceramic Substrate

Metallized Large Ceramic Substrate

Kyocera's ceramic metallization technology achieves larger component sizes, high positional accuracy by leveraging large substrate forming technology, and high-precision post-firing laser processing and patterning. Additionally, we offer a wide range of pattern materials such as Ag, Cu, Pt, glass, and resistors, allowing you to select the optimal material according to your needs.

Features

  • Larger Size
    Compatible with large substrates up to 330mm square. *Please inquire for even larger sizes.
  • Wide range of materials
    From ceramic materials such as alumina, silicon nitride, and aluminum nitride, to pattern materials like Cu, Ag, and Pt, and even plating materials, you can select the optimal material for your application.
  • High Positional Accuracy

Printed Resistance / Trimming

By adopting printed resistors, the following advantages can be obtained compared to chip resistors.
・Improved mounting area efficiency and design flexibility due to reduced number of components.
・High-precision resistance value adjustment through laser trimming (Adjustment tolerance: ±2%).
・Functional trimming allows for resistance optimization per component.
・Ensures high heat dissipation with a printed structure, achieving improved rated power.
*Please consult regarding the trimming processing range, as there are limitations.
