Webinar recordings about our Powerelements

In cooperation with Altium, we hosted a live webinar with the following content:

  • Design criteria in high power electronics 
  • High current contacts and their placement methods – What to look for in high current PCB connections
  • Altium Designer implementation – how to analyze voltage waveforms and current densities and use Altium A365 for collaborative design reviews with your manufacturer

In this webinar, our power element specialist Günter Behlau will present the Press-Fit Specification 5.1 for the design of printed circuit boards. The following topics will be explained in more detail:

  • Basics of printed circuit boards – through-hole plating and layer thicknesses
  • Tolerances of printed circuit boards
  • Effects of deviations

Whether for cable, busbar, board to board or components connection – High current applications need reliable connecting solutions. In this webinar, our Powerelement specialist Günter Behlau presents the topics below:

  • PCB technology in power electronics
  • Assembly methods and design guidelines for high current contacts
  • The reliability of the Powerelements based on current-carrying capacity and mechanical stability illustrated by reference projects

In cooperation with Vogel Communications Group Verlag and Wieland Werke AG, we organized a live webinar with the following content:

  • Classification lead(-free): The background to RoHS, Reach and ELV
  • The lead-free challenge: Alternatives to lead as a component in copper alloys – qualification, availability and market trends
  • Production of lead-free Powerelements: Insights from qualification – processing, products and applications
