Press-Fit Technology 

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

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

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.
