PCB Tools: Design & Calculations

We found two very essential tools for PCB design and fabrication. These tools help to design various PCB features easily.

[1] Saturn PCB Design Toolkit
Saturn PCB Design INC provides this tool free of cost, thanks to them for this good tool for all PCB designers.This software allow to design the following features with great Ease:
  • Via - The through hole interconnect can be modeled for parasitic using this tool. You can also find out the Current Rating, Resonant Frequency and Power Dissipation
  • Trace Width Calculations
  • Transmission Line and Signal property calculations
  • Differential Pair Line design
  • Pad Stack Calculations
  • Crosstalk Calculation
  • Current carrying capacity for critical power traces
  • Embedded Resistances on PCB
  • Thermal Calculator for heat dissipation design
  • Planar Inductor design
  • And Many more very use full tools.
.In fact this tool is updated to IPC-2152 Standard for the PCB design as per industry standards.
Thanks to DP for publishing about this tool

[2] Footprint Expert from PCB Libraries
 This tool is quint-essential if you design complex footprints for the PCB. In general may IC vendors provide the PCB footprint dimensions. However if you want to design as per standard to be Maximized, Normalized or Small footprint dimensions it is not possible. This tool is IPC-7351A compilant and provides a wide verity of footprint design tools.
This also has an inbuilt library that helps you to find commonly used  once the calculator has found your desired dimensions of the PCB footprint the same can be replicated onto a library editor. This tool not only provides the way of calculating footprint but it also has Silkscreen, Solder-mask and Paste generation. Additionally the software automatically updates itself over the net to give the updated libraries of the components.
