WEBVTT - PCB traces impedance calculation with QuickField 00:00.000 --> 00:13.000 Hello everybody and welcome to our webinar. My name is Vladimir, and together with my colleague Alex we will discuss calculation of the impedances for printed circuit board traces with QuickField. 00:13.000 --> 00:20.000 But before we start speaking about this, let me briefly outline capabilities of QuickField software for those who never heard about it. 00:23.000 --> 00:34.000 QuickField is a finite–element analysis system for simulating of the variety of problems in electrical engineering, airspace design, thermal engineering, biology, medicine and other fields of science and technology 00:34.000 --> 00:50.000 Set of analysis modules include three suites – Magnetic, Electric and Thermo-structural, which may be further split into DC Magnetics, AC Magnetics, Transient Magnetics, Electrostatics, DC, AC and Transient conduction, Static and Transient heat transfer and stress analysis modules. 00:51.000 --> 01:05.000 These types of analysis may be performed individually or in combination, which makes QuickField a powerful tool for complicated Multiphysics analysis. This slide shows types of field coupling directly supported by QuickField 01:06.000 --> 01:15.000 Directly means that there are more sophisticated ways to perform complicated studies, where core QuickField functions are not enough. 01:15.000 --> 01:37.000 QuickField features open object interface, which we call ActiveField, and this is a technology for combining QuickField with other software applications, including Microsoft Office components, MATLAB or even custom programs written on many current development platforms (C++, Python, Java etc). 01:37.000 --> 01:50.000 And most important – all this variety of features is extremely user friendly, and implemented such way that basic operations with QuickField may be performed without any dedicated training. 01:50.000 --> 02:08.000 This means that QuickField customers range from high school students, who need simple field mapper for school project – to most advanced projects run by national laboratories and NASA, leading technological corporations like Siemens or SONY, top scientists and engineers around the world. 02:08.000 --> 02:16.000 What is particular application, where QuickField is most efficient – it is hard to say. There are so many fields where QuickField is proven effective. 02:16.000 --> 02:20.000 Today we will show you how to use QuickField for designing the printed circuit boards. 02:20.000 --> 02:30.000 Specifically – how to calculate the microstrip impedance, differential impedance, capacitance and inductance matrix for particular trace design 02:30.000 --> 02:46.000 Together with losses calculation (which also may be estimated with QuickField) this gives the PCB designer all information needed for calculating the board or PCB transmission lines parameters. 02:46.000 --> 02:59.000 My colleague Alex will use this application to demonstrate using of QuickField both via its user interface, and through the programming interface ActiveField. 02:59.000 --> 03:06.000 Now lets listen Alex live presentation. Thank you. 03:06.000 --> 03:12.000 On this webinar we will review 6 examples. 03:12.000 --> 03:25.000 1. Single trace microstrip line. The capacitance inductance and the impedance of the line will be calculated 03:26.000 --> 03:39.000 2. The strip line of a pair of conductors the differential impedance is calculated 03:40.000 --> 04:02.000 3. Calculate parameters of equivalent circuit to simulate transient pulse propagation. And we will run the transient simulation too 04:02.000 --> 04:06.000 These were three basic examples. And there are three advanced examples 04:10.000 --> 04:20.000 4. Losses calculation in traces and dielectric 04:20.000 --> 04:34.000 5. Some configurations require 3D analysis. So we will simulate 3D microstrip crossover. 04:35.000 --> 04:45.000 6. The last we will calculate capacitance and inductance matrix in case of multi trace line.
