The collection grows step by step.
Power Tree
Power distribution on the PCBA: currents through the converter cascade, utilisation against ratings, heat dissipation per component, nominal and worst case.
Trace width
Minimum width for a given current at a permissible temperature rise, for outer and inner layers, in millimetres or mil.
Clearance and creepage
Minimum distances by pollution degree, material group and working voltage, for basic and reinforced insulation.
Impedance
Line impedance for microstrip, stripline and differential pairs from stack-up, trace width and dielectric.
Layer stack-up
Build-up of a multilayer board with copper thicknesses, prepregs and cores, including finished thickness and reference planes.
Via current capacity
Permissible current per via from drill diameter, plating thickness and layer count.
Copper area and heat
Copper area required to remove heat from a component, with thermal resistance and temperature rise.
