Abstract
A method for manufacturing a multilayer circuit board includes providing an inner circuit substrate defining a through hole, attaching a support plate to the inner circuit substrate to seal an opening of the through hole; placing an electronic module in the through hole; pressing a first substrate onto a surface of the inner circuit substrate; removing the support plate; pressing a second substrate onto another surface of the inner circuit substrate, the first substrate and the second substrate infilling the through hole and jointly encapsulating the electronic module; forming a first conductive wiring layer on a surface of the first substrate facing away from the first surface to obtain a first circuit substrate, and forming a second conductive wiring layer on a surface of the second substrate facing away from the second surface to obtain a second circuit substrate. A multilayer circuit board is also disclosed.
