Derating

The numbers specified in datasheets are usually only accurate in ideal, laboratory conditions.  And the real world is nothing like a laboratory.  So individual values will fluctuate with temperature, age, voltage, current, etc...

The process of adjusting the value down from the specified value is referred to as derating.  It is done by either looking at a graph, called a derating curve, or by following an equation.


Design for Manufacture

Not everything that can be drawn in a cad program can be made in a factory.  Design For Manufacture is a series of checks that ensure that a printed circuit board can be built in a factory.
