Abstract:
1. A method for manufacturing circuit modules, the method comprising: preparing a module substrate defined by an aggregate substrate including a plurality of small substrates; mounting circuit components on the module substrate; forming an insulating resin layer on substantially an entire top surface of the module substrate such that the circuit components are disposed in the insulating resin layer; forming a first shielding layer on a top surface of the insulating resin layer; forming first through holes in the module substrate and in the insulating resin layer at locations corresponding to portions of boundary lines of the plurality of small substrates so as to extend in a thickness direction of the module substrate and the insulating resin layer; forming first electrode films in inner surfaces of the first through holes so as to be connected to the first shielding layer; filling the first through holes with a filling material; forming second through holes in the module substrate and the insulating resin layer at locations corresponding to the remaining portions of the boundary lines of the plurality of small substrates so as to extend in the thickness direction of the module substrate and the insulating resin layer; forming second electrode films in inner surfaces of the second through holes so as to be connected to the first shielding layer and the first electrode films; and cutting the filling material with which the first through holes are filled along the boundary lines of small substrates, resulting in a division of the aggregate substrate into the plurality of small substrates.
