I recently designed a piece of in-house gear that uses the PCB as part of
the protective earth GND return. At first I thought I would be forced to use
a wire(s) only (which was awkward given the mechanics of the unit) but then
was convinced that EN61010 did not require it. To get around the via is
Chris,
I have estimated this type of thing in the past assuming adiabatic
conditions. That is, the energy put into the material heats it and no energy
is lost during the heating. This gives the worse-case temperature rise. So,
what is needed is the electrical resistance of the material and the spe
What is needed is the I squared t rating of the breaker. Then the (I^2)(t)
rating of the PCB. Then you know if the PCB can take it.
