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.
