Electromagnetic Shielding (EMI/ EMS)

EMI or EMS is of importance for consumer electronics, inudstrial and medical applications. Radio-frequency (RF) or electromagnetic radiation can be blocked basically by two types of coatings:

• Conductive films
• Magnetic films

Testing

• Sheet resistance
• Conductivity
• Thickness
• Homogeneity
• Shielding behaviour at certain frequencies

Application

• Deposition process control
• Quality control

Substrates

• Foil
• Plastics
• Glass

Processes

• S2S
• R2R

Environment

• In-vacuo/ In-situ
• Ex-vacuo/ Ex-situ
• Wet and dry
• Inline
• Offline

For characterization of deposition processes in electromagnetic shielding SURAGUS refers to the following products:
