Abstract
In a circuit module, a conductive partition is defined by a plurality of conductive chips provided on a component mounting surface. The component mounting surface is divided into a first block and a second block by the conductive partition. The shape of the conductive partition can be freely changed in accordance with the size of a circuit board and the arrangement of electronic components in the first block and the second block by changing the positions of the conductive chips and the number of conductive chips. Electromagnetic interference between the first block and the second block is prevented by the conductive partition.
Claims8
A circuit module comprising:
- a circuit board including a component mounting surface on which a plurality of electronic components are mounted;
- and
- a conductive partition that is provided on the component mounting surface of the circuit board along with the plurality of electronic components and is configured to define blocks of electronic components;
- an insulating resin layer arranged on the circuit board so that the insulating resin layer covers the plurality of electronic components;
- and
- a shield conductive layer covering the insulating resin layer;
- wherein
- the conductive partition is defined by a plurality of conductive chips;
- each of the plurality of conductive chips includes a base, a through-hole passing through the base in a direction parallel or substantially parallel to the component mounting surface, a supporting portion, and a suction portion;
- the through-hole of each of the plurality of conductive chips is filled with a resin of the insulating resin layer;
- and
- the plurality of conductive chips are partially exposed on the surface of the insulating resin layer, and are connected to the shield conductive layer.
