Heavy Cu/Al Wire Bonding Tools

UPT heavy wire wedge tools are built for power packaging — bonding heavy aluminum and copper wire in modules where current capacity, thermal cycling and long production runs demand exceptional tool durability. An ultra-long-lifetime, no-clean design reduces tool changes and keeps bonders running, while V-groove and G-groove foot geometries ensure stable wire capture and consistent deformation across large wire diameters. For copper wire applications, a dedicated tip treatment counters the higher hardness and abrasiveness of Cu, significantly extending tool life in copper-intensive production.
