Abstract
An ultrasonic wire bonder is disclosed having a bonding head for bonding wire to an electrical or electronic component with a bonding tool. A flexible support formed from at least one arcuate arm, supports the bonding tool for flexible movement of the bonding tool in the Z axis. A pair of arms form a wire clamp supported on the flexible support and are articulated by a link connected for moving one of the arms with respect to the other by an electrical drive having a coil. A wire cutter is connected to the bonding head and a pusher pushes the wire cutter toward the bonding tool before wire is to be cut after bonding.
Claims31
An ultrasonic wire bonder comprising:
- a bonding head connected for Z axis movement over an electrical or electronic component to which a wire is to be bonded;
- an ultrasonic transducer having a bonding tool connected thereto for bonding a wire;
- and,
- a flexible support for supporting said bonding tool formed from at least one arcuate arm forming an arc within a plane intersecting the Z axis connected to said bonding tool for flexible movement of said bonding tool in the direction of the Z axis.
An ultrasonic wire bonder having a bonding head comprising:
- a bonding tool connected to said bonding head;
- a pair of arms comprising a wire clamp one of which is fixed and the other movable for clamping the wire to be bonded;
- a flexible support connected to said arms comprising at least 2 pairs of arcuate arms surrounding a common Z axis mounted to the bonding head and, each pair of arcuate arms are spaced from each other along said Z axis;
- a link connected for moving said movable arm laterally with respect to the fixed arm to form a clamp for said wire;
- and,
- an electrical drive having a coil for moving said movable arm by said link against the fixed arm.
A wire bonder having a bonding head connected for movement in a Z axis over an electronic or electrical component to which a wire is to be bonded comprising:
- a bonding tool connected for movement in the Z axis on a flexible support;
- an electrically biased forcer for forcing said bonding tool against a wire that is to be bonded;
- a wire cutter connected to said bonding head for cutting movement in the Z axis spaced laterally from said bonding tool prior to cutting movement;
- a linkage for moving said cutter laterally toward said bonding tool substantially closing the space between said wire cutter and said bonding tool when wire is to be cut after bonding to place the end of said cutter in lateral proximate relationship to said bonding tool during wire cutting;
- and,
- an electrical drive for driving said linkage toward said bonding tool.
A method for ultrasonically bonding a wire to an electrical or electronic component comprising:
- providing a support for a wire bonding head that can move said head in the Z axis;
- providing a wire bonding tool;
- and,
- supporting said bonding tool on at least two arcuate arms having a plane that intersects the Z axis while performing said bond.
A method of ultrasonically bonding a wire to an electrical or electronic component comprising:
- supporting a wire bonding tool on a bonding head for movement in the Z axis;
- providing a wire cutter for movement in the Z axis with a gap between said wire cutter and said wire bonding tool prior to cutting;
- moving said wire cutter laterally into lateral proximate relationship to said wire bonding tool substantially closing the gap between said bonding tool and said wire cutter;
- and,
- cutting a bonded wire while said wire cutter is in proximate longitudinal relationship to said bonding tool and said gap has been closed.
An ultrasonic wire bonder comprising:
- a bonding head connected for Z axis movement over an electrical or electronic component to which a wire is to be bonded;
- an ultrasonic transducer having a bonding tool connected thereto for bonding a wire;
- and,
- a flexible support for supporting said bonding tool formed from at least two pairs of at least two arcuate arms, each of said pairs of arcuate arms spread from each other along the Z axis.
