The extraction device (14) comprises a suction arm (26), a fan and an outlet opening (34). The suction arm (26) includes a suction head (28), which comprises a suction opening (32), and a suction base (30), which comprises an air duct for conducting the air. The air duct is arranged downstream of the suction opening (32). The is configured to suck in the air from the area above the cooking hob (12) through the suction opening (32) and the air duct. The outlet opening (34) is configured to exhaust air. According to the invention, the suction arm (26) is centrally arranged or arrangeable in relation to the cooking hob (12) or is arranged or arrangeable midway between the lateral edges of the cooking hob (12).

Abstract: A wire guide module for an ultrasonic wire bonder, comprising a body made of a thermally stable metallic and/or ceramic material, wherein an elongated wire feed-through channel having a wire inlet opening and having a wire outlet opening is provided on the body, and comprising a guide tube provided in the wire feed-through channel. In addition, the invention relates to a thermosonic wire bonder having a wire guide module.

Abstract: A method for bonding large modules with the following steps, a large module is fed to a bonder from behind in a loading plane by means of a feeder unit. The large module is passed from the feeder unit to a first transverse conveyor unit, and is brought by the same to a first buffer position provided in the bonder, wherein the first buffer position is provided in a loading plane of the bonder. The large module is brought from the first buffer position into a first receiving position in the loading plane via the first transverse conveyor unit and is passed there to a vertical conveyor unit.

Abstract: A calibration method for a bonder. Characteristics of a force actuator of the bonder are measured and stored in such a way that the force actuator can be controlled optimally during production operation of the bonder on the basis of the measured data. Further, a device for fully automatic or partially automatic bonding force calibration.

Abstract: A wire brake for use with automatic wedge bonding machines which have cutting pliers arranged behind the associated bonding tool and movable along the bonding wire for detaching bonding wire from the open pliers. The wire brake includes guiding members having a plurality of deflectors that can be applied to the bonding wire, the guiding members having two planes from which the bonding wire can be laterally deflected. A central deflector is provided for deflecting the bonding wire from the planes. The central deflector projects between the two planes for guidance of the bonding wire and is displaceable transverse to the longitudinal extension of the bonding wire. Additional guiding members are arranged opposite the planes such that the bonding wire rides between the central deflector and the additional guiding members when the bonding wire is deflected.
