ZeDry®/H2 Lid consists of a metal lid, coated with a solventless, thermally cured getter layer engineered for high capacity moisture and hydrogen uptake. Lid material, shape, dimensions and finishing are specified by customers.
ZeDry/H2 Lid is designed for hermetic optoelectronic and microelectronic device packaging. The ZeDry/H2 getter coating deposited on the lid works as a reversible getter for moisture and irreversible getter for hydrogen: it has to be activated with a thermal process at 100°C-120°C, just before the device sealing.
The ZeDry/H2 Lids can be provided in a variety of metals (e.g. Al, Ni, Au, Stainless Steel, KOVAR) and engineered metal alloys (e.g. Ni/Au-plated KOVAR). Ceramic and glass can also be considered as options, for special applications.
