Patent number: 7352070Abstract: Improved encapsulated, overmolded and/or underfilled electrical components having a complete encapsulation, overmolding and/or underfilling with a coefficient of thermal expansion that is uniform and substantially free of gradients includes a polymeric matrix and an inorganic filler having a platelet geometric structure. The platelet structure of the filler allows a desirable coefficient of thermal expansion to be achieved using a very low level of filler material. This low level of filler material facilitates lower viscosity during forming of the encapsulation and/or overmolding, thereby facilitating complete filling of a mold cavity and underfilling of space between a circuit board and a semi-conductor chip electrically connected to the circuit board. In addition, the low viscosity has processing advantages that reduce the potential for damage to electrical components during encapsulation, overmolding and/or underfilling.Type: GrantFiled: June 27, 2003Date of Patent: April 1, 2008Assignee: Delphi Technologies, Inc.Inventors: Thomas S. Ellis, Glen E. Novak, Bruce A. Myers, Scott D. Brandenburg, Jeenhuei S. Tsai
