Fellow Members,
I am looking for a method to calculate the resistance of a ceramic chip
that has been terminated on two ends with palladium-silver.
The chip is rectangular [3D] in shape.
L= 0.079"
W=0.051"
H= 0.021"
The terminations form a band around the edges. Measurements have shown that
the resistance varies with the width B of the Palladium Silver Band.
Electrical paths on the surfaces are shorter than those in the middle.
Knowing the geometry, the thickness of the palladium-silver and the
resistivity of the ceramic material, is there a method, a table, or a
formula that allows us to calculate the resistance. Also, knowing the
resistance, can we calculate the width of the termination band B.
Your help with this problem is highly appreciated.
With kindest reagards, I remain,
Sincerely yours,
Nasser Y. El-Awar
