Summary
Stickies particles :
» Most harmful ministickies are mainly mini PSA : Pressure Sensitive Adhesives
Ingede Method #4 :
»Pressing deformation
» No 3D info
» Noinformation on nature
» Time Consuming
Automated stickies 3D STICK measurement method :
» Determines the 3D morphology of screened particles (without any deformation)
» Classifies the particles as stickies among contaminants. This is achieved by a
combination of laser triangulation and local nearinfrared (NIR) spectroscopy.
The Device principle :
» Determination of contaminant morphology in 3D (3DMAP)
» Stickies identification by neay infrared spectroscopy (NIRS)
Richer information :
» 3D morphology
» Macro contaminants classified by their chemical nature
» Not restricted to stickies (plastics)
Non Contact method:
» Stickies are not pressed
» Real size is measured
» Link to exposure index
