There are many different types of lead finishes presently used on components. Can they all be reliably plated to?

Answer: The base metal on most components today is copper and it is possible to remove the finish to expose copper, which can be reliably plated to. This has been well demonstrated over the history of PCB technology. There are some Alloy 42 lead frame materials in use but mostly for ceramic packages. Plating processes and compensatory measures, within the improved process and/or upstream in packaging technologies will arise. Wholesale change is not expected to happen over night. These solutions will be rolled out over time, along with support technologies and infrastructure. Logic and economics indicate that there should be only a limited number of package types and finishes in the future.
