Claim 8

The kit of claim 1 wherein a sufficient quantity of a polymeric adhesive is provided as an element of the kit in dry sheet, paste, powder, gel or liquid form.

Claim 9

The kit of claim 7 wherein said polymeric adhesive is provided in the form of a dry sheet.

Claim 10

The kit of claim 8 wherein said polymeric adhesive is provided in the form of first, second and third sheets of adhesive, said first sheet of adhesive comprising a ring for bonding said base component to a leadframe, said second sheet of adhesive comprising a generally rectangular portion for bonding said metallic base component to a centrally positioned die attach pad of said leadframe and said third sheet of adhesive comprising a ring for bonding said metallic cover component to said leadframe.

Claim 11

The kit of claim 9 wherein said kit includes an adhesive vent plug for sealing the vent hole in said metallic cover component.

Claim 12

The kit of claim 9 wherein said first and second sheets of adhesive are tacked to said metallic base component and said third sheet of adhesive is tacked to said metallic cover component.

Claim 13

A kit for the assembly of an adhesively sealed package designed to encase an electronic device, which kit comprises: a metallic base component selected from the group consisting of aluminum and aluminum base alloys, said base component having a first surface and an opposing second surface, said first surface having at least selected portions thereof adapted to receive a polymeric adhesive by coating with an anodization layer: a metallic cover component selected from the group consisting of aluminum and aluminum based alloys, said metallic cover component having a bonding surface for bonding to a window frame component and an opposing surface, said bonding surface having an outer ring portion and an inner portion bordered to said ring portion, sand ring portion adapted to receive a polymeric adhesive and coated with an anodization layer; and said window frame component selected from the group consisting of aluminum and aluminum base alloys having an anodization layer coating all surfaces and edges, said surfaces adapted to receive a polymeric adhesive.

Claim 14

A kit for the assembly of an adhesively sealed package designed to encase an electronic device, which kit comprises: a metallic base component selected from the group consisting of aluminum and aluminum base alloys, said base component having a first surface and an opposing second surface, said first surface having at least selected portions thereof adapted to receive a polymeric adhesive by coating with an anodization layer: a metallic cover component selected from the group consisting of aluminum and aluminum based alloys, said metallic cover component having a bonding surface for bonding to a window frame component and an opposing surface, said bonding surface having an outer ring portion and an inner portion bordered to said ring portion, sand ring portion adapted to receive a polymeric adhesive and coated with an anodization layer; and said window frame component selected from the group consisting of aluminum and aluminum base alloys having an anodization layer coating all surfaces and edges, said surfaces adapted to receive a polymeric adhesive.

Claim 15

The kit of claim 12 wherein said polymeric adhesive is provided in the form of first, second, third and fourth sheets of adhesive, said first sheet of adhesive comprising a ring for bonding said metallic base component to a leadframe, said second sheet of adhesive comprising a generally rectangular portion for bonding said metallic base component to a centrally positioned die attach pad of said leadframe, said third sheet of adhesive comprising a ring for bonding said metallic cover component to said window frame component and said fourth sheet of adhesive comprising a ring for bonding said window frame component to said leadframe.

Claim 16

The kit of claim 13 wherein said kit includes an adhesive vent plug for sealing a vent hole in said metallic cover component.

Claim 17
