Claim 8:
9. A method for reducing etching due to galvanic effect in a printed circuit board in an electronic device, the method comprising:
determining a ratio of a surface area of a contact finger to a surface area of an exposed portion of a contact trace electrically connected to the contact finger, wherein the contact finger is configured to provide an electrical connection to an external electronic device;
determining whether the ratio exceeds a predetermined threshold;
responsive to determining that the ratio exceeds the predetermined threshold, separating the exposed portion of the contact trace into a via connection pad and an outer connection pad configured to be coupled to an impedance trace, wherein the via connection pad and outer connection pad are physically separated by a separation distance;
plating the contact finger and the via connection pad with a common material; and
electrically connecting the via connection pad and the outer connection pad using a solder joint.
