Creepage and Clearance on Printed Circuit Boards This article by Dirk Müller focuses on the fundamental problems of the emergence of creepage paths and electric flash-over and flash-through on printed circuit boards of high voltage as they are used on electric motors in electric vehicles (EV). To address such problems he discusses the option to identify these situations early in the design process with NEXTRA® to allow avoidence of such before going into production.

Creepage and Clearance on pcbs for power applications. In this article (in german language) Dirk Müller adresses the specific requirements for the design of PCBs of power electronics concerning the problem of creepage and clearance. Traces to pins of IGBTs and MOSFETs need to honour certain minimum clearances to avoid flashthough or flashover or create creepage paths. The analysis for obeying such requirements can esily done with NEXTRA®.

"Multidesign - editing multiple pcb designs within a 3d environment"
Cit. (translated from german language): "For the first time it is possible to open up multiple pcb design from different 2d design systems in one mechanical CAD environment and edit contours, placement and routing of the pcbs.". In this (german language) paper Dirk Müller explaines the NEXTRA® features to edit multiple pcbs from any 2d pcb system together in one application.

"Efficient design of flex boards by computer aided tools."
The role of flex circuitry carriers within a product is twofold: electronic as well as mechanical. Up to now it was necessary to use two different CAD systems to design a flex board because of this twofold nature. Mecadtron CEO Dr. Thomas Krebs shows how this complex task can be efficiently managed within one application by using the tool NEXTRA®. Read more
