The layer 21 is provided with an outgoing light transmitting portion 210 corresponding to the light transmitting portion 230. In the embodiment, the first lacquer layer 21 at least partially shields the illuminating portion 30. Further, the first lacquer layer 21 completely shields the illuminating portion 30. The light source of the illuminating portion 30 can pass through the transparent portion 230 first. The light guide (refracting or reflecting) is transmitted to the outgoing light transmitting portion 210, so that the light source that is transmitted can be soft and not glare; in other embodiments, the light emitting portion can also be not covered by the first paint layer, but is facing The light-emitting portion is disposed; or, the portion of the light-emitting portion is shielded by the first paint layer and partially blocked.

The light-emitting portion 30 is embedded in the substrate 23, and the light source of the light-emitting portion 30 can be projected onto the light-transmitting portion 230 and emitted to the outside of the dynamic random access memory 1 via the outgoing light-transmitting portion 210. The substrate 23 is a translucent substrate of a general printed circuit board. In other embodiments, only the light transmitting portion is a light transmissive material layer, and other portions of the substrate are opaque material layers, so that the light emitting portion can be partially buried. The light-emitting surface of the opaque material layer directly faces the light-transmitting portion emitting light source; or the light-transmitting portion is a hollow structure, and the light-emitting surface of the light-emitting portion is exposed to the hollow structure, and the light-emitting effect can also be achieved.

The substrate 23 is provided with a memory module 233, the transmission port 40 is disposed on the substrate 23, and the transmission port 40 is electrically connected to the memory module 233. In more detail, the light-emitting portion 30 is also electrically connected to the substrate The transmission port 40 (of course, the light-emitting portion can be additionally electrically connected to other external power sources such as a motherboard). It can be understood that the transmission port 40 can transmit not only power but also transmission. data.

In this embodiment, the substrate 23 further has a second surface 232 opposite to the first surface 231. The body 20 includes a second lacquer layer 22 disposed on the second surface 232. The second lacquer layer 22 is at least The light-emitting portion 30 is shielded from the portion (of course, the second lacquer layer may not directly block the light-emitting portion to directly transmit light).

In this embodiment, the first lacquer layer 21 and the second lacquer layer 22 are insulating varnish layers on a general circuit board, and the outgoing light transmitting portion 210 is an unpainted hollow structure; in other embodiments, the exiting The light transmitting portion may also be a light transmissive material layer, and the light may be transmitted through.
