H2O AND VOC GETTER LIDS
ZeDry®/VOC Lid consists of a metal lid, coated with a solventless, thermally cured getter layer engineered for high capacity moisture and volatile organic compounds (VOCs) uptake. Lid material, shape, dimensions and finishing are specified by customers.
ZeDry/VOC Lid is designed for optoelectronic and microelectronic device packaging, both hermetic and semi-hermetic architectures.
The ZeDry/VOC getter coating deposited on the lid works as a reversible getter for moisture and for VOCs (e.g. methyl-ethyl ketone or toluene): it has to be activated with a thermal process at 100°C-120°C, just before the device sealing.
The ZeDry/VOC 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.
