Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
105 words
An electronic component, comprising a member consisting of: a ceramic board substrate having a metallized surface formed thereon; a metal alloy layer coated on the substrate, the metal alloy layer consisting essentially of nickel and cobalt, wherein the cobalt is contained in an amount of 7 to 40% by weight, wherein the metal alloy layer is formed in a thickness of 0.5 to 5 microns; and a gold-plated outer surface layer coated on said metal alloy, said gold-plated outer surface layer forming the outer-most surface of the electronic component, wherein the gold-plated outer surface layer is formed in a thickness of 0.5 to 2 microns.
Claim 2
Dependent Claim
105 words
