摘要:
Apparatus for ultrasonic bonding wire connection of circuits to electronic components comprises a casing-like carrier member carrying a bonding assembly mounted therein so as to pivot about an axis (Z), and including a first support frame operatively connected to an electromotive drive and a second support frame constructed for receiving an energy transducer carrying a capillary element. In a first movement phase of the bonding assembly, both support frames are jointly movable about the axis (Z) and in a second movement phase, the second support frame with the energy transducer is movable about an articulation (Z') spaced from the axis (Z) relative to the first support frame. For obtaining the necessary positional stability of the second support frame, a common mass center of the individual elements is located within a circle, the center of which is located between the axis (Z) and the articulation (Z').
摘要:
Described is a solid dishwashing agent for dishwashers that can be placed within the dishwasher once for several washing cycles and that can be automatically dosed according to the actual need. Said solid dishwashing agent in general is in one piece and comprises a carrier and therein incorporated active substances that at least comprise a builder. Said carrier is a solid, water-soluble matrix that is tight against water and humidity, and forms a dishwashing agent that is dimensionally stable at the highest temperature in the storage container during a washing cycle.
摘要:
An apparatus for performing an exact in-feed in the X and/or Y direction in the plane of a bond head, e.g. a gripper, to a working station containing a sliding plate, a support element, a first and second drives for performing the in-feeds, a guide mechanism provided with a slide part and a guide part and an integrated measuring device for determining movements of the support element oriented in the X and/or Y direction. The support element is mounted in the horizontal plane with translational and rotational degrees of freedom by a vacuum-pressurizable air bearing on the sliding plate and vertically by a vacuum-pressurizable air bearing on the slide part, the latter additionally being mounted with a vacuum-pressurizable air bearing on the sliding plate and with a counterpressure air bearing between two webs of the guide part.
