Test wafers were fabricated by an IC supplier and bumped with electroplated eutectic Sn/Pb by a third party. Issues associated with transferring integrated circuit data to printed circuit design software were identified. The bare and bumped wafers were characterised to identify possible criteria for lot qualification.
