    摘要: An apparatus and method are provided for continuously injecting molten solder into a plurality of molds for transfer of the formed solder mounds to electronic devices such as multilayer ceramic packages. A conventional injection molding apparatus is employed with a specially designed apparatus for forming the molds and preferably with a specially designed mold to provide a continuous molding process. The apparatus is preferably of a U-shaped configuration whereby molds are advanced under the molten solder reservoir and injection head by a preceding mold in the apparatus. The urging action of the preceding mold on the succeeding mold and, preferably in conjunction with the preferred mold design, enables a continuous method and apparatus for injecting molten solder into a plurality of molds. The preferred mold design utilizes an upper plate having mold opening, and a lower substrate or backing plate, with the length and width of the upper plate being slightly longer than the length and width of the lower substrate or late.

    摘要: An apparatus and method are disclosed for laser raster scanning a substrate in an XY plane wherein a single motor is used to provide synchronized X-Y scanning by two mirrors positioned orthogonally and which move linearly in an XY plane relative to each other by the rotation of the motor shaft. A preferred embodiment uses a specially designed cam to provide back and forth laser scanning motion and an intermittent gear to provide indexing of the laser. The apparatus and method may be configured for various scan speeds, spot sizes, Y-axis indexing and X-axis scan at the object plane. Over scanning of the active XY area of the object plane is preferred to provide constant velocity and energy density over the active XY area.
