This calculator helps translating the color bars from the resistor to its value. Our friends at Flomerics have posted an interesting article [1] that describes some of the shortcomings of the IPC-2221 design rule for determining the current carrying capacity of PCB traces. 725 where k, b, and c are constants resulting from curve fitting to the IPC-2221 curves Disclaimer: These calculations are believed to be correct, but not guaranteed. Trace Width Calculator & other calculatorsAnother point to consider is the distance between conductors across a dielectric. Once the Hole Size is established, the main point for pad size calculation in the IPC-2221 standard is the minimum annular ring of the plated through-hole pad stack after fabrication tolerances are applied. The formula will enable you to find the tolerable current conducted through a particular trace. 60 mm (4) Level A Pad Diameter = minimum hole size + 0. To use it, first select the tolerance of the resistor: 10%, 5% or equal or smaller than 2%. Avoiding common flex PCB errors will enhance the stability of your design. where k, b, and c are constants resulting from.
