Surface contamination involving micrometric particles, microbiological agents, molecular adsorbate and others, represent a significant hazard in many areas of industry. For instance, high-level cleanliness is a critical requirement that any EEE device has to fulfil at any development stage: from the fabrication process of single components, before encapsulation, to the final PCB assembly.
