  • Quencher clamping operation using an electromagnet
    Patent number: 6192709
    Abstract: A method of embedding a magnetically attractable member (25) in a ceramic material (1) and a system therefor wherein there are provided a magnetically attractable member and a ceramic member capable of being placed in a molten state. The magnetically attractable member is disposed over the ceramic member and the ceramic member is placed in a molten state. The magnetically attractable member is then disposed in the molten ceramic member by magnetic attraction and the molten ceramic member is then hardened around the magnetically attractable member. The magnetically attractable member is taken from the class consisting of Alloy 42 and Kovar. The ceramic member is preferably a glass. The ceramic member is preferably disposed on a semiconductor package and the magnetically attractable member is preferably at least a portion of a semiconductor lead frame.
    Type: Grant

  • Model generator for constructing and method of generating a model of an object for finite element analysis
    Patent number: 5581489
    Abstract: A model generator and method of generating a model of an object for use in finite element analysis is provided. The model generator (24) includes an input data storage (12) with an output coupled to an input of a materials information generator (14) and an input of a mesh processor (16). The materials information generator (14) has an output coupled to a second input of the mesh processor (16). The mesh processor (16) has an output coupled to a thermal conditions processor (18) and a second output coupled to an output generator (20). The thermal conditions processor (18) has an output coupled to a third input of the mesh processor (16). The output generator (20) has an output coupled to an input of an output storage (22).
