The multiskin Technology
Traditional setup: Integrated setup:
Integrated Setup
Stability Less individual parts, less interfaces, less prone to failure Highly automated production process, high yield, no manual
assembly Compact layer stack, no moving parts, no air gap Close surfaces, protection against dust and humidity
Form factor and design Complex 3D-forms Touch-friendly surfaces Thin design height
Benefits of the Integrated Setup
MID (Molded Interconnect Devices) Conductive structures processed directly on
or into the molded part 3-D mounting of the electric components
Example: 2-K injection-molding, LPKF-LDS ® Process
In-molded Plastic Films Processing on a plastic film Forming, in-molding
Example: plastic electronic multiskin® films
Technologies
… for integrated control consoles
Décor and function can be on one plastic film Processing of décor and conductive structures as well as mounting
of the components can be done on a flat substrate Flexibility in further processing
Forming In-mold processing Back-foaming Plastic film could already be a integrated control panel
Benefits of using Plastic Films
multiskin integrates electronic functionsand décor on one plastic film.
Electronic functions + décor = multiskin film
multiskin film-inserts are ready for injection-molding.multiskin film + injection-molding = control panel
multiskin Films
multiskin films are multi-layer plastic filmsInterface Layers / Décor Layers / Functional Layers

Electronic components likeLEDs, connectors, passive and active components
are presented to multiskin films by pick and place in a sheet-process.
are mounted on multiskin films using special assembly techniques like conductive glueing and selective soldering.
