Primoceler, ON Semiconductor to Provide Hermetically Sealed CMOS Sensors for ESA
TAMPERE, Finland — Laser glass-welding firm Primoceler has teamed up with ON Semiconductor to provide hermetically sealed CMOS sensors for European Space Agency orbital missions.
Based on ON Semiconductor’s HAS3 hermetic design, the sensors are encased in an impermeable seam of glass using laser welding technology, which helps to avoid any problems due to pressure and temperature changes and the vacuum of space.
Glass offers a fully hermetic seal of all components, the company said, along with an extremely small heat affected zone during the welding process.

- A noncrystalline, inorganic mixture of various metallic oxides fused by heating with glassifiers such as silica, or boric or phosphoric oxides. Common window or bottle glass is a mixture of soda, lime and sand, melted and cast, rolled or blown to shape. Most glasses are transparent in the visible spectrum and up to about 2.5 µm in the infrared, but some are opaque such as natural obsidian; these are, nevertheless, useful as mirror blanks. Traces of some elements such as cobalt, copper and...
