Abstract
A circuit board includes a circuit substrate, a heat dissipation dielectric film and a ground circuit board stacked orderly. At least one conductive structure passes through the heat dissipation dielectric film to electrically connect the circuit substrate and the ground circuit board. An insulating layer is disposed on a side of the circuit substrate facing away from the heat dissipation dielectric film. The circuit board further includes at least one connecting unit. Each connecting unit passes through the insulating layer to be electrically connected to the circuit substrate. A height of each connecting unit is gradually increased from a center of the connecting unit to a periphery of the connecting unit. A method for manufacturing a circuit board is provided.
