ABSTRACT:
An electronic conductor and a method for manufacturing it are provided. The conductor is made of a base of substantially copper having a diffusion barrier on the base and a coating of tin-lead, or of tin, on the diffusion barrier. The diffusion barrier is either copper in combination with phosphorus, or copper in combination with boron. The method of manufacturing an electronic conductor applies the diffusion barrier to the base by means of an electro-deposition process and then applies the coating on the diffusion barrier.
