Press-fit technology is one of the core competences of the Würth Elektronik Intelligent Connecting Systems.

before / after

Thanks to the specific benefits of press-fit technology for printed circuit board connectivity, effective problem solutions become both possible and practical, for example

Elimination of complex and fault-prone wiring
Simple realisation of plug and play systems
Simple realisation of three-dimensional design through right-angled press-fit connectors
Compact realisation of keypads and control panels

The benefits of press-fit technology

As compared with conventional solder technology, the use of press-fit technology shows a number of advantages:

possibility for populating both sides of the printed circuit board without added expense
elimination of thermal stress of the printed circuit board
elimination of soldering errors such as, for example, cold solder places, solder short-circuits, …
screw mountings are no longer necessary
elimination of flux residues which can result in contact faults
in comparison to machine soldering, size restriction of the assemblies to be processed no longer has to be considered
long plug connector posts remain clean (no solder) and can be used as male connectors on the other side of the board
assemblies with press-fit technology are also best suited for high-frequency applications as printed circuit board impedances can be specifically defined
simplification of repairs due to easily exchangeable connectors
high environmental compatibility

press-fit technology

Würth Elektronik ICS have specialised in the implementation of solid press-fit technology for high current applications. In a series of theoretical and experimental investigations, we could scientifically prove that solid press-fit technology is outstandingly suitable for use in this area due to the optimum electrical properties.
