Abstract
Abstract A molding process and resulting product is disclosed in which a printed circuit pattern carrier is placed in a mold and is molded to an insulation carrier. The insulation carrier is disclosed as a printed circuit board or the interior of the insulation housing for an electrical product. Plural laminations molded atop one another are disclosed. The printed circuit carrier has mold gate openings to enable molding of features which extend above the plane of the conductive layer. A printed circuit pattern is applied before the molding step.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
101 words
A molded printed circuit board comprising a generally flat molded body portion of electrical insulation material having top and bottom generally parallel surfaces; a conductive patterned foil disposed atop said top surface and firmly adherent thereto; and at least one molded projection of electrical insulation material integrally joined to said molded body portion, extending from said flat molded body portion and above the plane of the surface of said conductive patterned foil, and having its sides free of conductive material; said projection extending from an area of said molded body which is spaced inwardly from the periphery of said molded body.
Claim 2
Dependent Claim
101 words
A molded printed circuit board comprising a generally flat molded body portion of electrical insulation material having top and bottom generally parallel surfaces; a conductive patterned foil disposed atop said top surface and firmly adherent thereto; and at least one molded projection of electrical insulation material integrally joined to said molded body portion, extending from said flat molded body portion and above the plane of the surface of said conductive patterned foil, and having its sides free of conductive material; said projection extending from an area of said molded body which is spaced inwardly from the periphery of said molded body.
Claim 3
Dependent Claim
24 words
The molded printed circuit board of claim 1, wherein said conductive pattern includes a portion thereof which extends to the base of said projection.
Claim 4
Dependent Claim
20 words
The molded printed circuit board of claim 1, wherein said projection contains a central well for receiving a semiconductor die.
Claim 5
Dependent Claim
24 words
The molded printed circuit board of claim 1, which includes a second conductive foil pattern disposed atop and insulated from said conductive patterned foil.
Claim 6
Dependent Claim
112 words
A continuous flexible web of identical molded printed circuit boards, each of said boards comprising: a generally flat molded body portion of electrical insulation material having top and bottom generally parallel surfaces; a conductive patterned foil disposed atop said top surface and firmly adherent thereto; and at least one molded projection of electrical insulation material integrally joined to said molded body portion, extending from said flat molded body portion and above the plane of the surface of said conductive patterned foil, and having its sides free of conductive material; said projection extending from an area of said molded body portion which is spaced inwardly from the periphery of said molded body portion.
Claim 7
Dependent Claim
112 words
A continuous flexible web of identical molded printed circuit boards, each of said boards comprising: a generally flat molded body portion of electrical insulation material having top and bottom generally parallel surfaces; a conductive patterned foil disposed atop said top surface and firmly adherent thereto; and at least one molded projection of electrical insulation material integrally joined to said molded body portion, extending from said flat molded body portion and above the plane of the surface of said conductive patterned foil, and having its sides free of conductive material; said projection extending from an area of said molded body portion which is spaced inwardly from the periphery of said molded body portion.
Claim 8
Dependent Claim
26 words
The molded printed circuit board of claim 1, wherein said molded projection is formed in the same molding operation as said generally flat molded body portion.
Claim 9
Dependent Claim
26 words
The molded printed circuit board of claim 5, wherein said molded projection is formed in the same molding operation as said generally flat molded body portion.
