Ceramic Lids

Innovative Ceramic Combo Lid

As the industry's cover lid innovator, Materion manufactures a variety of high performance hermetic lids to meet your microelectronic packaging application whether for the semiconductor, MEMS, medical, or optical market. In response to customer requirements for a non-magnetic hermetic cover that could be metalized, we developed the Ceramic Combo-LidTM.

A variety of elements must come together to manufacture the new Lid. Our metallization process creates effective organic free seal rings that allow excellent soldering, while a gold-tin alloy delivers perfect hermetic sealing. Other non-precious and lead-free soldering can also be used.

In addition, Materion can produce edge metallization. This unique feature assures high performance and quality of the sealed packages at the customer end.

Customized Ceramic Combo-LidsTM

Materion is tooled for over 15,000 preform shapes which allow us to custom-design and manufacture the new Ceramic Combo-Lid™ to meet specific customer requirements. The lids are available in a variety of shapes, sizes, materials and configurations. We also offers the service of tack welding solder preforms onto ceramic lids.
