Abstract
Flexible circuitry has been used for years in the electrification of instrumentation displays and audio systems. As the complexity of these systems increases, there is a greater need to integrate more functions. Opportunities for integration exist from lighting to full modular assemblies. Modular includes heating, ventilating and air conditioning (HVAC) and audio functions. Flexible circuitry is an attractive power distribution medium for this integration because of its:
Ability to mount electronic components directly on to the flex substrate to eliminate satellite boards and connectors.
Ability to conform to 3D configurations and package more functions in a smaller area.
• “Modular” multilayer capabilities for putting density where needed.
Ease of assembly using flex based self aligning or wipe in style connection systems.
Ability to directly replace wiring harnesses in most applications.
• Lower overall system cost.
This paper discusses integration opportunities in all these areas in light of technology trends.
