At this moment you can use this PCB Toolkit for iOS to calculate:

- Maximum conductor length / bandwidth
- Conductor Impedance (also differential)
- Via properties
- Via θ (Thermal resistance), and for a via array
- Low Pass Π-filter
- Fusing current (Preece, Brooks & Onderdonk)
- Maximum current or width for a trace

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 is designed in a neutral color, so it will not disturb in all kinds of background-light conditions.
