Substrate structure
View Patent ↗It is intended to provide a substrate structure ensuring a shielding property and a heat discharge property of a resin part that collectively covers a plurality of electronic components and capable of downsizing, thinning, and a reduction in number of components. The substrate structure 20 of the first embodiment is provided with a substrate 21 , a plurality of electronic components 22 mounted along the substrate 21 , and a resin part 25 that covers the electronic components 22 and is in close contact with the substrate 21 . In the substrate structure 20 , the resin part 25 is provided with a reinforcing heat discharge layer 26 covering the electronic components 22 and having a heat conductivity and a reinforcing property and a shield layer 27 covering the reinforcing heat discharge layer 26 , and a surface o 28 of the shield layer 27 is formed into a predetermined shape corresponding to a surface structure of the display device 30 adjacent to the resin part 25.
1. A substrate structure, comprising:
a substrate;
a plurality of electronic components mounted on the substrate;
a resin part including a reinforcing heat discharge layer and a shield layer,
the reinforcing heat discharge layer coating the electronic components and having a heat conductivity and a reinforcing property, and
the shield layer being provided on the reinforcing heat discharge layer;
wherein a platform is provided by a surface of the shield layer, the platform being configured to receive a device other than the plurality of electronic components; and
wherein an upright wall part is provided around a periphery of the platform and surrounds the device when present.
2. The substrate structure according to claim 1 , wherein a recessed part corresponding to a projection of the device is provided on the platform.
3. The substrate structure according to claim 1 , wherein the device is a display device, the platform having a lower end and an upper end and being inclined upward from the lower end to the upper end, the platform forming a light guiding plate inclined surface for the display device, and any of the electronic components having a large mounting height among the electronic components is/are adjacent the upper end of the platform.
4. The substrate structure according to claim 1 , wherein the device is a display device, and at least one of the platform and the wall part is provided with a reflection layer.
5. The substrate structure according to claim 4 , wherein the reflection layer is a sheet disposed on a surface of the resin part.
6. The substrate structure according to claim 4 , wherein the reflection layer is coated on the surface of the resin part.
7. The substrate structure according to claim 1 , wherein a metal plate is exposed to the surface of the shield layer.
