Ceramic Lids

Ceramic lids can be used on almost any package style or type, although the most common use is on Cerquad and Cerpac style packages. They typically feature a high-temperature glass sealant for hermetic applications or a low-temperature B stage epoxy sealant where hermeticity is not a concern. Another common use of ceramic lids is on packages where low sealing temperatures are required.

Ceramic lids come in a variety of sizes, shapes, and thicknesses. They are also available with glass or quartz windows for EEPROM applications.
