While pre-baking a hermetic package may prevent some outgassing, hydrogen may still be released inside the package over time. Hydrogen reacts with Oxygen to produce moisture which then can corrode. Hydrogen can also attack palladium and platinum semiconducting gates in microwave chipsets (e.g. GaAs) causing failure.
To address this issue, the Hi-Rel has developed hydrogen getter solutions in several different formats – a foil getter, as well ink and tablet getters - for multiple product applications and industries. Our offerings are described below, but if you have a unique requirement, please let us know. We work very closely with our customers to develop custom solutions.
