Customer Cases

Anti-corrosion coating for sensors

The challenge

Common scintillator materials include Cesium Iodide (CsI) and Sodium Iodide (NaI), which are sensitive to moisture. Competitive product lifetime requires a thin film encapsulation coating.

The customer

A leading scintillator plate manufacturer.

Beneq solution

ALD coating was applied on almost finished sensor assemblies to coat surfaces that are exposed to corrosive gases. Highly conformal and pin-hole free ALD coating solved the corrosion problem without compromising the sensor sensitivity.
