TactoTek IMSE Benefits
Light weight
Reduces weight 50-70 % no separate light guides and large PCBs
Space efficientUp to 90% less assembly depth
Design freedom
New feature/function possibilities seamless surfaces
Fast product updatesEasy model-specific versioning single component customization
Durable and reliable Shock and impact resistant, protected from moisture and debris
Faster to service Single part replacement reduces time up to 40 %
Simple assembly30 % savings from fewer parts and electrical connections
Scalable mass production
Standard equipment and known materials
Excellent touch response
Printed touch controls very close to finger
Improved antenna performance
Antenna radiator closer to surface can follow the 3D contour
Example: HMI Control Panel

IML film with visual finish
Printed circuitry, capacitive controls, SMD LEDs and ICs on IML film
Injection-molded plastic
Traditional Design Example
Design Properties• Limited design possibilities• Assembly depth: 25+ mm• Multiple discrete components• Multiple electro-mechanical interfaces
TactoTek Structural Electronics Design
Design Properties• Design freedom• Wall thickness: ~3 mm• 50-70% less weight• Single-component solution
Surface plastics (IML film and molded plastic)
Flex for capacitive controls
Light pipes
Full width rigid PCB
TactoTek test example• Two film structure• All electronics in-mold• PASSES (Cap touch, lighting, visual quality)
▪ -40…+80 cycling▪ 85°C/85%RH▪ Vibration
Customer designs• Several products under Automotive OEM tests• Some products for wearable parts approved
Every IMSE design needs testing, different• Geometry• Materials• Electronics
