Clearance and creepageare two parameters that are related to the distance required between conductors on a circuit board. The distance between two conductors or nodes, measured in air, is referred to as the clearance distance. IPC-2221 defines optimum clearances related to different aspects of the ...
Beyond the IPC-2221 Calculator Please take note that the standards of IPC-2221 are voluntary. However, for the products that safety standards cover as defined in the electrical and building codes, the clearance and creepage requirements in the IEC or UL standard could be mandatory. Take for ins...
