    摘要： According to the present invention, a plastic land-grid array package, a plastic ball-grid package, and a plastic leaded package for micromechanical components are fabricated by a molding process characterized by placing a sheet-like protector on the surface of the components during the molding phase, selectively encapsulating the bonding pads and coupling members of the chip while leaving empty space above the components, removing the protector and attaching a lid over the components. A molding method as well as a molding apparatus are provided compatible with the sensitivity of the micromechanical devices, yet flexible with regard to the technique used to assemble the chip and the substrate. Furthermore, the method disclosed is flexible with regard to the material and the properties of the substrate. The invention is applicable to a variety of different semiconductor micromechanical devices, for instance actuators, motors, sensors, spatial light modulators, and deformable mirror devices. In a key embodiment of the invention, the micromechanical components are micromirrors for a digital mirror device.

    摘要： A method and apparatus for encapsulating an integrated circuit die and leadframe assembly using liquid mold compound. A prepackaged liquid mold compound insert 11 is placed in a rectangular receptacle 43 in a bottom mold chase 31. The receptacle 43 is coupled to a plurality of die cavities 37 by runners 39. Leadframe strip assemblies containing leadframes, integrated circuit dies, and bond wires coupling the leadframes and dies are placed over the bottom mold chase 31 such that the integrated circuit dies are each centered over a bottom mold die cavity 35. A top mold chase 53 is placed over the bottom mold chase 31 and the mold compound package 11. The top mold chase 53 has die cavities 57 corresponding to those in the bottom mold chase 31. The prepackaged liquid mold compound is packaged in a plastic film which has heat sealed edges 15. The mold compound is forced through the heat seals 15 during the molding process by the pressure applied by a rectangular plunger 61. The plunger is applied using variable speed and pressure to control the rate the mold compound fills the cavities in the top and bottom mold chases, thereby avoiding voids in the completed packages and minimizing wire sweep of the bond wires of the integrated circuit assemblies.

    摘要： A method and apparatus for encapsulating an integrated circuit die and leadframe assembly. A prepackaged sproutless mold compound insert 71 is placed in a rectangular receptacle 91 in a bottom mold chase 81. The receptacle is coupled to a plurality of die cavities 85 by runners 87. Leadframe strip assemblies containing leadframes, integrated circuit dies, and bond wires coupling the leadframes and dies are placed over the bottom mold chase 81 such that the integrated circuit dies are each centered over a bottom mold die cavity 85. A top mold chase 90 is placed over the bottom mold chase 81 and the mold compound package 71. The top mold chase 90 has die cavities 95 corresponding to those in the bottom mold chase 81. The mold compound insert 71 is preferably packaged in a plastic film 75 which has heat sealed edges 77. The mold compound is forced through the package 75 and heat seals 77 during the molding process by the pressure applied by a rectangular plunger 101. The sproutless mold compound insert is packaged so that the mold compound will exit the packaging only where runners intersect the receptacle. The sproutless mold compound insert requires no alignment or cutting tools within the mold station. The plunger is applied using variable speed and pressure to control the rate the mold compound fills the cavities in the top and bottom mold chases, thereby avoiding voids in the completed packages and mining wire sweep of the bond wires of the integrated circuit assemblies.
