Abstract:
A filament bundle is rewound from a reel, and passes through various sorts of liquid in processing vessels to be used for plating. The filament bundle passes through a fixed guide roller and a movable guide roller while it travels within the liquid in the processing vessel. The movable guide roller is moved periodically, the filament bundle is stretched and slackened by turns, whenever the filament bundle is slackened or untied, the bundle is loosened. The filament bundle with each filament subjected to the plating is taken up to a take-up reel.
Abstract:
A method for encapsulating flip chip interconnects includes applying a limited quantity of encapsulating resin to the interconnect side of an integrated circuit chip, and thereafter bringing the chip together with a substrate under conditions that promote the bonding of bumps on the interconnect side of the chip with bonding pads on the substrate. In some embodiments, the step of applying resin to the chip includes dipping the interconnect side of the chip to a predetermined depth in a pool of resin, and then withdrawing the chip from the resin pool. In some embodiments the step of applying resin to the chip includes providing a reservoir having a bottom, providing a pool of resin in the reservoir to a shallow depth over the reservoir bottom, dipping the chip into the resin pool so that the bumps contact the reservoir bottom, and then withdrawing the chip from the resin pool. Also, apparatus for applying a precise volume of encapsulating resin to a chip, includes a reservoir having a bottom, and means for dispensing a pool of encapsulating resin to a predetermined depth over the reservoir bottom.
Abstract:
The invention relates to transporting rollers (22) for transporting essentially flat articles, to holding-down means (23) for pressing the articles onto transporting rollers (22), and to a transporting system (30). In this case, the transporting roller (22) is of at least two-part configuration and comprises a spindle element and at least one track element (1), the latter enclosing the spindle element in a tubular manner. The invention consists in designing transporting rollers (22) such that the spindle element is flexurally rigid, and in presenting an essentially cylindrical holding-down means (23) which is of at least two-part configuration and comprises a spindle (8) and at least one sleeve (13), wherein the internal diameter of the sleeve is larger than the external diameter of the spindle, the spindle (8) and the sleeve (13) of the holding-down means are coupled, and a pin-like carry-along element which is oriented away from the spindle (8) and engages in a cutout (16) on at least one side of the sleeve (13) is fitted on the spindle (8). The invention allows articles to be processed continuously, while keeping to the correct track as precisely as possible, with careful handling, in the case of which, under a wide range of different conditions in respect of temperature, pressure and surrounding medium, the workpieces are exposed to only a low level of mechanical loading.
Abstract:
An installation for painting objects, in particular vehicle bodies (4), has at least one bath (2, 3) containing a treatment fluid in which the objects (4) are to be immersed. The objects (4) are guided through the installation in a continuous or intermittent translatory movement with the aid of a conveyor device (5). A plurality of immersion devices is provided, which support the objects with the aid of a supporting structure (44). The latter is connected to the conveyor device (5) by way of a connecting structure. Each connecting structure has at least one steering linkage which in turn comprises two steering means (40, 41, 42, 43) arranged at a distance from one another. The steering means (40, 41, 42, 43) are each rotatably connected to the conveyor device (5) at one end and rotatably connected to the supporting structure (44) at the other end. At least one device (45 to 52) ensures that at least one of the two steering means (40, 41, 42, 43) of the steering linkage can be rotated about the axis produced by its articulated connection to the conveyor device (5). It is possible for very different kinematics of the immersion and removal movement to be realised with the aid of the immersion device described, including those movements in which the object is lowered in parallel alignment with its original orientation and those in which the object is rotated about a horizontal axis.

A method of coating a photoconductive element for an electrophotographic image forming apparatus and an apparatus therefore are disclosed. A plurality of cylindrical bodies are immersed in a bath, which stores a coating liquid, at the same time and then lifted out of the bath. As a result, a photoconductive film is formed on each cylindrical body.

Abstract:
A method and apparatus for achieving a level exposed surface of a viscous material pool for applying viscous material to at least one semiconductor component by contacting at least a portion of the semiconductor component with viscous material within a reservoir. A level viscous material exposed surface is achieved by using at least one mechanism in association with the reservoir. The mechanism is configured to level the exposed surface of viscous material and maintain the exposed surface at a substantially constant level. The reservoir may be shaped such that the exposed surface of viscous material is supplied to a precise location.

Abstract:
Embodiments of the invention generally provide a substrate processing system and method. The substrate processing system generally includes two primary components. The first component is an interface section having at least one first substrate transfer robot positioned therein, and the second component is at least one processing module in communication with the interface section, the at least one processing module having a pretreatment and post treatment cell, a processing cell, at a second substrate transfer robot positioned therein. The substrate processing method generally includes transporting a dry substrate to a processing module via a dry interface. Once the substrate is positioned in the processing module, a robot transfers the substrate between a treatment cell and a processing cell contained within the processing module to complete a predetermined sequence of processing steps. Once the processing steps are completed, the treatment cell generally dries the substrate and then the substrate is transferred back to the dry interface.
