The castellated nozzle includes a body having a plurality of castellations protruding therefrom, with each of the castellations having a contact surface thereon. A channel is formed adjacent to at least one castellation of the plurality of castellations. An opening extends through the body for introducing a heated gas therein. The contact surfaces of the plurality of castellations are aligned to a respective plurality of leads. Typically, the castellated nozzle includes a first plurality of castellations forming a first row and a second plurality of castellations forming a second row. A channel is formed adjacent to at least one castellation. The first and second plurality of castellations are arranged in a staggered format wherein at a first point along the length of the opening one of the castellations in the first row is located opposite to one of the channels of the second row, and wherein at a second point along the length of the opening one of the channels in the first row is located opposite to one of the castellations in the second row. An opening is formed between the first and second row. The castellated nozzle includes a hole for aligning the castellated nozzle to a flexible circuit carrier.

摘要： A soldering tip overcomes the gravitational effects on molten solder and supplies a large molten solder sphere for contact with a surface to which solder is to be applied. A conical or cylindrical spiral or helix of solder-wettable material, preferably in the form of a compressional spring is attached to the soldering tip with the central axis of the helix aligned with the axis of the soldering tip, preferably by welding. Solder supplied to the soldering tip flows between the coils of the helix and forms a meniscus at the lower end of the helix so that only the molten solder meniscus touches the surface during application of solder. The increased surface tension acts to overcome gravitational effects and assures a more even flow of solder to the surface.

摘要： The invention is comprised of a method and apparatus for inspecting substrates and hat sink hat assemblies to determine whether the chips on the substrate and pistons on the heatsink hat assembly are matched. The inspection is carried out by separately illuminating both the substrate and the heatsink hat assembly in such a way that a bilevel image of each assembly is created. Each assembly has an associated image-acquisition device, such as a television or video camera which captures the bilevel image. These images are then converted to an array of image points. The points of the image of the substrate assembly are compared with a preset pattern to determine whether a chip is missing. A similar comparison is done with the points of the image of the heatsink hat assembly to determine whether any piston is missing. A deviation from the expected pattern will be communicated to an operator who will take corrective action.

摘要： In manufacturing packaged modules for computer systems, many modules require sealing a lid to a lower substrate by using solder around the outer edges of the lower substrate. When the solder is heated, it often flows inward towards the chips on the substrates (solder intrusions) and may cause shorts. This invention solves the problem of solder intrusions by using a graphite lid seal fixture during lid seal. The fixture is comprised of lower and upper parts. The substrate, which has a sealband area, rests on and is held in place by the lower part of the fixture. The upper part of the fixture rests on the lower part. The lid, which has solder on its lower surface which is slightly smaller but otherwise generally matches the sealband area of the substrate, fits in a hole in the upper part and rests on the substrate. Thus, graphite substantially surrounds the edges where the lid and substrate meet and the fixture evenly distributes the heat around the sealband during reflow so that the solder can flow out towards the edge of the sealband. By this means, areas where solder flows back into the interior of the module are reduced and hermeticity yields are improved.
摘要翻译：在制造用于计算机系统的封装模块中，许多模块需要通过在下基板的外边缘周围使用焊料将盖子封闭到下基板。当焊料加热时，它通常向内流向基板上的芯片（焊料入侵），并可能导致短路。本发明通过在盖密封期间使用石墨盖密封夹具来解决焊料侵入的问题。夹具由下部和上部组成。具有密封带区域的基板由固定装置的下部支撑并固定在适当位置。夹具的上部位于下部。其下表面上具有焊料的盖子稍微较小，但通常与基板的密封带区域匹配，该盖子装配在上部的孔中并且搁置在基板上。因此，石墨基本上围绕盖和基板相遇的边缘，并且固定装置在回流期间将热量均匀地分布在密封带周围，使得焊料可以朝向密封带的边缘流出。通过这种方式，焊料流回到模块内部的区域减少，气密产率提高。

摘要： A device which is located between a carburetor and an engine intake manifold of an internal combustion engine includes oppositely rotating impellers mounted on air bearings. The air-fuel mixture exiting the carburetor impinges on the impellers and drives those impellers. Fuel droplets in the mixture are broken up to form a mixture capable of almost total burnout.
