Abstract:
A method of making a circuitized substrate, said method comprising:providing a layer of dielectric material;forming at least one hole within said layer of dielectric material wherein said at least one hole is provided in said layer of dielectric material using a process selected from the group of processes consisting of drilling, punching and laser ablation;forming an electrically conductive layer on said at least one hole within said layer of dielectric material;positioning a thin layer of support material on said layer of dielectric material and over said at least one hole;positioning a quantity of fill material on said thin layer of support material following said positioning of said thin layer of support material on said layer of dielectric material; andapplying a predetermined force onto said quantity of fill material while said quantity of fill material is subjected to a predetermined pressure and temperature sufficient to deform said thin layer of support material wherein said thin layer of said support material is ruptured in the area of said at least one hole as a result of said applying of said predetermined force and cause at least some of said fill material to substantially permanently fill said at least one hole.
