Flat plate cooling using a thermal paste retainer

An electronic package including:

• at least one chip mounted on a surface of a carrier,
• a cooling means having a surface opposing a surface of said at least one chip and said carrier,
• a space between said at least one chip and said surface of said cooling means defining a paste gap containing a viscous thermal material, and
• a partition surrounding at least a major portion of said at least one chip and spaced therefrom and forming a capillary at a periphery of said at least one chip said, capillary containing said thermal material,
• wherein said partition is fired within a groove in said surface of said cooling means.

• a partition surrounding at least a major portion of said at least one chip and spaced therefrom and forming a capillary at a periphery of said at least one chip, said capillary containing said thermal material,
• wherein said partition contacts a surface of said carrier.

A structure for mounting art electronic component comprising:

• a carrier connected to said component;
• a thermal material contacting said component;
• cooling means contacting said thermal material;
• and
• a grid connected to said carrier and said cooling means, said grid including cells having a dimension larger than that of said component, one of said cells receiving said component, such that said grid causes said thermal material to be retained substantially between said component and said cooling means.
