Saturn PCB Toolkit

Saturn PCB Toolkit gathers in one place the calculations that printed circuit board designers need every day: characteristic impedance of microstrip, stripline, differential pair and coplanar conductors, trace width and resistance from current and temperature rise to IPC-2152, via current capacity, fusing current, minimum conductor spacing, planar inductor inductance, power distribution network target impedance and crosstalk. It also has wire gauge, drill and screw tables and a unit converter. Limitations: Windows only, the download goes through a request form on the site, and the crosstalk calculator is marked unsupported.
