Where coating quality determines product function
In printed electronics, the coating is the product. A conductive ink trace that varies in thickness may fail to carry its design current. A sensor element with uneven reagent produces unreliable readings. Coating quality determines whether the product works at all.
Substrates are thin flexible polymer films (PET, PEN, polyimide). Contamination control is critical — a single particle can cause an electrical short.
Coating methods
Slot die for precision control, clean edges, wide viscosity range. Precision servo positioning, Coriolis flow control.
Gravure for thin uniform coatings at higher speeds. Precision doctor blades, enclosed chambers.
Multi-station lines for multi-layer functional structures.
Contamination control
Enclosed stations, HEPA-filtered air, sealed web paths, non-shedding surfaces. Cleanroom-compatible designs.
Thin film web handling
Closed-loop tension, low-inertia idler rolls, sub-millimeter web guiding. Registration systems for pre-patterned substrates.
Drying and curing
Multi-zone convection, UV curing, IR drying — integrated and coordinated with web transport.
Process control
Recipe management, real-time monitoring, trend data for correlating parameters with product performance.
