About three quarters of the production costs for plastic microsystems are due to finishing and mounting processes as well as to connecting the miniscule devices to their macroscopic surroundings.
In this phase thinXXS relies on its extensive know-how in glueing, bonding, or welding to assemble, for example, medical, optical, mechanical, or microchemical components.
Other typical backend processes are the integration of gold or platinum microelectrodes on polymer surfaces, the systematic manipulation of surface properties like hydrophilicity and hydrophobicity, or the local coupling of functional groups as used in many life science applications.
The functionality of microfluidic products relies beside the size and tolerances of the micro features mainly on the surface properties due to the comparable large surface to volume ratio.
Our process technology for coating and conditioning microstructured plastic components allows to adapt and extend the product functions by electrical, optical, fluidic or even chemical properties. These are for example, the application of conductive tracks and highly reflective coatings, the coating of plastics by glass-like layers, the hydrophilic or hydrophobic surface modification, the application of functional groups adapted to specific molecular interactions or the increase of the chemical resistance.
