Printed Electronics Using Polymer Pastes At Würth Elektronik

WÜRTH ELEKRONIK is using Printed Polymere as an alternative to assembly

Reducing the overall height and size of an assembly requires increased integration of functionalities into the printed circuit board. Based on conductive polymers, flat components such as robust contact areas, intelligent connection systems or complex resistors can be realized on the inner and outer layers.

Printed polymer technology can be used to realize the following components and applications:

Keyboards
Switches
Resistors

The latter can be placed on the inner and outer layers. The possible applications range from pull-up/pull-down resistors to voltage dividers, potentiometers, pulse resistors and heaters.

This technology is used in the automotive, medical, building, household and security technology sectors as well as in commercial vehicles.

Advantages of Würth Elektronik Printed Polymer Technology

Possible Savings Due to Elimination of Assembly Costs

Reduction in Overall Height Due to Flat Components

Miniaturization Through Integration of Components in the PCB

Fewer Solder Joints

High Reliability in Case of Temperature Changes and Vibrations

Can Be Combined With Other Technologies Such as HDI Microvia, RIGID.flex or Thermal Management

Know How Basics

The print is used as a passivation of the copper to prevent from oxidization and to achieve a constant contact resistance during the lifetime.
The contact resistance is influenced by the contact material and the contact pressure and is normally < 20 Ω.
Two areas with a different electrical potential are shorted by conductive rubber mats or metal contact springs.
Switches are used with sliding contacts; two contact areas of different electrical potentials are shorted by the slider.
