PCB Toolkit

Your PCB design pal on the iOS platform!

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)
• Electrical clearance (IPC2221B)
• Pull Up calculator I2C

And now also:

• LED Resistor Calculator
• Mounting Hole Info
• Nearest E-Series Resistor Calculator (Solo/Serie/Parallel)
• Resistor Tolerance / Alpha Viewer
• Via Stitching Calculator
• Cload Calculator (XTAL)

And also links to standard house stackups of JLCPCB, PCBWAY and Aisler are included.

I will add more calculations with updates. (One time buy, so you will get these updates without additional charge later) I am also open to feature requests.

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