    摘要: In accordance with an embodiment, a molding apparatus comprises a screen having a planar top surface; a recess in the screen and extending below the planar top surface; a blade capable of traversing the planar top surface; and a molding compound applicator. Another embodiment is a method for molding. The method comprises providing a substrate in a confined volume with an open top surface, applying molding compound in the confined volume, and traversing the open top surface with a blade thereby forming the molding compound to have a planar surface that is co-planar with the open top surface. The substrate has at least one semiconductor die adhered to the substrate.

    摘要: A combined mixing and injecting device includes a housing having a pressure chamber and containing two plungers with one being sleeved around the other. The plungers have top ends formed with pistons which respectively extend into upper and lower chambers of the pressure chamber to be operated by a fluid, and bottom ends with tapering end faces extending into a bottom space below the lower chamber to perform a camming action. A mixer disposed below the housing includes a mixing chamber and valve units having valve stems respectively controlled by actuating elements which in turn are managed by the camming action of the plungers. The valve stems are connected to slide seats slidable along radial directions and spaced apart around the housing. The actuating elements actuate the slide seats so that the valve stems are operated to open or close inlet holes communicated with the mixing chamber.
