Expanding on the capabilities of its Cupra copper capillary, Kulicke & Soffa Industries Inc. (K&S) has developed the CupraPlus, which it said supports highly consistent and stable fine-wire second bonds while maintaining the quality of the overall wire-bonding process. ~{!0~}The formation of a fine-wire second bond in fine copper wire bonding has been a constant obstacle, mainly due to frequent tail bond failures, inconsistent second bond strength and an unstable bonding process window,~{!1~} said Jack Belani, vice president of the marketing and business units at K&S. ~{!0~}With its unique design and properties, the CupraPlus copper capillary provides for increased second-bond pull strength for a more stable and consistent quality bond throughout a process.~{!1~} To meet different wire bonding challenges, the CupraPlus can handle copper wire from 0.8 mil to 3.0 thicknesses.
