Electronic circuit module component and method of manufacturing electronic circuit module component

摘要

An electronic circuit module component includes an electronic component, a substrate, a first resin, a second resin, a metal layer, and an opening. The electronic component is mounted on the substrate. The first resin has pores and is in contact with at least a part of the electronic component. The second resin covers a surface of the first resin and has porosity which is lower than that of the first resin. The metal layer covers the first resin and the second resin and is electrically connected to a ground of the substrate. The opening is provided in the metal layer and allows a part of the first resin to be exposed to an outside at least of the metal layer.

主权项

1. An electronic circuit module component comprising:
an electronic component; a substrate on which the electronic component is mounted; a first resin having pores and being in contact with at least a part of the electronic component, an average diameter of the sores of the first resin being at least 0.1 μm, but not more than 10 μm; a second resin that covers the first resin and has a porosity lower than that of the first resin; a metal layer that covers the first resin and the second resin and is electrically connected to a ground of the substrate; and an opening that is provided in the metal layer and allows a part of the first resin to be exposed to an outside at least of the metal layer.
