Abstract:
An apparatus for connecting an interconnect having a plurality of connections thereon to at least one contact area of a plurality of contact areas of a semiconductor die, said machine comprising:first axially movable structure attachable to a bare semiconductor die;second axially movable structure attachable to an interconnect;an ultrasonic vibratory actuator mounted to axially vibrate one of said semiconductor die and said interconnect;apparatus for axially moving said semiconductor die toward said interconnect whereby at least one connection of said plurality of connections of said interconnect contact said at least one contact area of said plurality of contact areas of said die; andapparatus for controlling said ultrasonic actuator to vibrate one of said semiconductor die and said interconnect while controlling an axial compressive force therebetween, whereby said at least one connection of said plurality of connections penetrates a portion of said at least one contact area of said plurality of contact areas of said semiconductor die to a predetermined depth.
