Abstract:
1. A component-embedded printed circuit board comprising: a first layered structure that includes a first insulator layer and a patterned first metal-foil layer that is formed on said first insulator layer and that has a plurality of spaced apart first foil traces, said first layered structure having a mounting side that has a build-up region and at least one mounting region, at least one of said first foil traces being disposed at said mounting region; a second layered structure that is adhesively bonded to said first layered structure and that includes a second metal-foil layer, a second insulator layer and a thermoset adhesive film, which are stacked one above another in the above order, said thermoset adhesive film being adhesively bonded to said second insulator layer and said build-up region of said mounting side of said first layered structure, said second layered structure being formed with a component-embedding hole that extends through said second insulator and said thermoset adhesive film to expose said mounting region of said mounting side of said first layered structure, said component-embedding hole being defined by a hole-defining surface that has top and bottom open ends and that extends entirely in a continuously downward direction from said top open end to said bottom open end, said second insulator layer having a hole-defining face that has an endless bottom peripheral edge, said thermoset adhesive film having a hole-defining face that has an endless top peripheral edge, said hole-defining face of said thermoset adhesive film cooperating with said hole-defining face of said second insulator layer to form said hole-defining surface that defines said component-embedding hole, said top peripheral edge entirely overlapping and contacting said bottom peripheral edge; and an electronic component fitted in said component-embedding hole.
