are recommended techniques
such as grooves and ribs which
may be used on a printed circuit
board to achieve desired creepage
and clearances. Creepage and
clearance distances will also
change depending on factors such
as pollution degree and insulation
level.
board, minimum creepage and
clearance requirements must be
met as specified for individual
equipment standards. For creep-
age, the shortest distance path
along the surface of a printed
circuit board between the solder
fillets of the input and output
leads must be considered. There
All Hewlett-Packard data sheets
report the creepage and clearance
inherent to the optocoupler com-
ponent itself. These dimensions
are needed as a starting point for
the equipment designer when
determining the circuit insulation
requirements. However, once
