A related question to current carrying capacity in circuits: Need a method of calculating current carrying capacity in screened silver polymer traces on 0.007" thick polyester membrane circuits. Resistance of the polymer per supplier data sheet is 0.015 ohms/square at 0.001" applied thickness. Typical width of screened trace is 0.025", and the actual thickness applied in most real designs is 0.0005". Length of the trace varies with application. Is there a formula for determining how much current can be carried by the circuit? Voltage is typically 5 VDC. *************************************************************************** * TechNet mail list is provided as a service by IPC using SmartList v3.05 * *************************************************************************** * To unsubscribe from this list at any time, send a message to: * * [log in to unmask] with <subject: unsubscribe> and no text. * *************************************************************************** * If you are having a problem with the IPC TechNet forum please contact * * Dmitriy Sklyar at 847-509-9700 ext. 311 or email at [log in to unmask] * ***************************************************************************
