3. Enclosure types
Here, we divide components into two types: discrete components (one chip per package) and modules (several chips per package, forming one or more elementary functions). This distinction is explained by the internal structure of the components:
discrete components have only two (in the case of a diode) or three (transistor, thyristor) terminals, connected directly to the chip terminals. In most cases, the heat exchange surface is not electrically insulated (it is one of the component's terminals);
modules have a variable number of terminals connected, via a more or less direct electrical circuit, to the terminals of several chips. Because of the multiplicity of electrical potentials present in the module, the substrate (which also serves as the thermal interface) must be electrically insulating. Consequently,...

Digital tools
In addition to power electronics "circuit" simulation tools such as Saber (editor: Synopsys), the design of power modules requires mechanical-thermal calculation resources. These include Ansys (Ansoft) and Comsol Multiphysics (Comsol), both based on the finite element method.
To optimize electrical performance, it is useful to be able to calculate the parasitic elements of the circuit, particularly...
Events
At European level, there are two main power electronics conferences, which include sessions on packaging: EPE (European Power Electronics) and PCIM (ower Conversion Intelligent Motion). The former is more research-oriented, while the latter is aimed more at industry, even if the boundary is sometimes blurred in a field as applied as power electronics.
Packaging is also discussed at power electronics conferences...
