PCB Toolkit

You can use this PCB Toolkit for iOS to calculate:

- Maximum conductor length / bandwidth (Hammerstad/Jensen & IPC)
- Conductor Impedance (also differential precise calculation by Kirschning/Jansen & IPC calculation)
- Via properties
- Via θ (Thermal resistance), and for a via array (IPC)
- Low Pass Π-filter
- Fusing current (Preece, Brooks & Onderdonk)
- Maximum current or width for a trace (IPC-2521 and IPC-2221)

And also a reference to standard house stackups of JLCPCB, PCBWAY and Aisler is included.

I will add more calculations with updates. (One time buy, so you will get these updates without additional charge later)



Who am I? I am an electronics and programming amateur. When I'm designing a PCB I found myself ALT-TAB-ing a lot and decided to make an app to use next to Altium Designer. This app is not meant as a source of additional income to me, but buying IPC standards and books just cost money. With your purchase I can buy these and process them for use in this app.

The app supports dark mode, portrait & landscape mode and zoomed-in display.
