Granted: 2003-02-11
Abstract: A process for the stereolithographic preparation of a three-dimensional object, wherein the object is built in a container which contains a radiation-curable liquid formulation with fillers by a repeated alternating succession of process steps (a) and (b), wherein in step (a) a layer of the radiation-curable liquid formulation, one limitation of which is the surface of the formulation, is cured using suitable radiation within an surface area which corresponds to the desired cross-section of the three-dimensional object to be formed at the level of this layer, and wherein in step (b) a new layer of the radiation-curable liquid formulation is formed on said cured layer, which process comprises homogenizing the radiation-curable liquid formulation during said process continuously or discontinuously to such an extent that there is no noticeable change in the filler content of the radiation-curable liquid formulation in the area of that layer with which the cured layer is coated in step (b). This process enables the skilled person, inter alia, to choose his fillers solely according to the purpose envisaged therefor without having to fear technical problems or problems relating to the quality of the stereolithographically produced object resulting from the sedimentation of the fillers during the preparation of the object.

Granted: 2000-07-21
Abstract: A system of solder ball placement and fluxless laser reflow on BGA packaging comprising means for template alignment, means for solder ball placement and a laser head. The template is aligned with connection pads located on the surface of the substrate without flux. The aligned template allows accurate guiding of the balls onto the pads by the ball placement means. One call is dropped into each hole in the template directly onto the pads in the  absence of flux. The solder balls positioned on the pads are then exposed to a laser via the laser head, resulting in the rapid melting of the solder balls directly onto the substrate pads. The melted balls are then allowed to cool rapidly. The present invention is preferably practiced on pads made from gold. The preferred condition for reflow is under nitrogen environment. Other types of pads composed of materials which are inert, do not oxidize readily in air and compatible with the solder ball reflow process are also compatible with the system according to the present invention.
