PCB Toolkit

Antonius Hurx

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.
