Pröll KG to showcase its portfolio at LOPEC 2019


Pröll KG from Weißenburg, Germany, will once again showcase its solutions for the printed electronics industry at LOPEC 2019, the leading European tradeshow for this sector.

The Hybrid PS Screen is a high-tech screen printing stencil, developed for industrial applications. The stencil shows excellent detail reproduction and highest print accuracy. Image carrier is a highly precise nickel shadow mask made by SPGPrints, fixed in a PET mesh. The hexagonal mesh design leads to a homogenous ink or paste transfer. Due to the excellent printing resolution of the stencil, line structures of >30µm can be realised. The accurate dimensional stability of the Hybrid PS Screen guarantees constant print runs and reduced production costs. Due to virtually distortion-free printing, accurate multi-layer sequences for the manufacture of complex micro electronic devices can be produced. The subsidiary Pröll Services GmbH Hildesheim is a leading supplier of technical screen printing screens.

NORIPHAN XMR is a halogen-free two-component ink system for IMD/FIM technology. NORIPHAN XMR is formable, shows extremely high wash-out resistance, outstanding cohesion in compound and long-term durability in the final part. The mild screen printing ink can be used as decorating ink or wash-out protective layer on PC films and PET films. NORIPHAN XMR shows high electrical resistance in capacitive fields. The black colour shades can be used for back printing of conductive pastes in functional IMD/FIM parts due to its non-conductivity. The highly resistant screen printing ink can be used for conventional printing applications as well. NORIPHAN XMR shows excellent adhesion on PC films, PC blend films, pre-treated PET films and corona treated PE and PP films. Even on various scratch resistant surfaces or hard coat lacquers and TPU materials a good ink adhesion can be achieved.

NORIPHAN HTR N is a proven, formable, backmoldable and solvent-based one-component screen printing ink for film insert moulding technology. Due to the development of the new opaque black colour shade NORIPHAN HTR N 990 NC, a carbon-free, non-conductive black is available for printed electronic applications now. The colour shade can be used for decorative prints but is mainly used for plane multi-layer printing or backing of metallic and polymer conductive pastes. Carbon-based pigments, so called carbon blacks, normally used for black colour shades, are electrically conductive and can interfere with the functional structures. The NORIPHAN HTR N 990 NC colour shade has been formulated and optimised regarding the interlayer adhesion and shows good adhesion in compound values in the final film/ink/injection material composition.
