WebThe original National Bureau of Standards set guidelines (IPC-2221 / MIL-STD-275) for current flow in FR-4 Printed Circuit Boards in 1956. Those numbers (10-15 A/mm2, internal layers de-rating up to 50% and via holes at 5-10 A/via)4 were based upon 1 ounce copper on trace with one ounce copper on the back side of a PCB. WebThis standard was originally cancelled in 1995 and replaced by IPC-D-275, "Generic Standard on Printed Board Design." In 1999, that supersession information was modified to additionally include IPC-2221, "Design Standard for Rigid Printed Boards and Rigid Board Assemblies."
