Genny, We try to keep process/materials consistent across all CMs. We qualify a primary material set and have an approved equivalent as a backup, because in some geographic areas, a particular brand name may not be available readily or a supplier may discontinue etc. We also conduct an audit of our CMs for process/materials compatibility with what we have approved. With lead free , this is even more critical.
