Abstract:
1. A circuit structure, comprising: a circuit board; an insulating layer configured on the circuit board and covering a circuit layer of the circuit board; a conductive via penetrating through the insulating layer and connected to the circuit layer, wherein the conductive via protrudes from a first surface of the insulating layer; a platable dielectric layer configured on the first surface of the insulating layer and having a trench pattern, wherein a protrudent portion of the conductive via protruding from the first surface of the insulating layer is located in the trench pattern and a material of the platable dielectric layer includes a chemical platable material; and a conductive pattern located in the trench pattern and connected to the conductive via, wherein there is a wedged mortise-and-tenon interface located between the conductive pattern and the protrudent portion of the conductive via.
