    摘要: A dynamic random access memory includes a main body which has a substrate portion and a light-emitting portion and a transmission port, the substrate portion includes a board and a first coating layer, the board has a light-transmittable portion and a first face, the first coating layer is coated on the first face and has an emergent light-transmittable portion corresponding to the light-transmittable portion, and the substrate portion has a memory module. The transmission port is disposed on the substrate portion and electrically connected with the memory module. The electronic device includes the dynamic random access memory and further includes a shell portion. The shell portion is covered on two opposite lateral faces of the dynamic random access memory and at least shields the light-emitting portion, and the shell portion further has a second light-transmittable portion corresponding to the emergent light-transmittable portion.

    摘要: Electrical components may be mounted on a printed circuit or other substrate. The electrical components may be covered with a conformal coating containing a wavelength-tuned-light-absorption-enhancement additive. The additive may be a dye or other additive that creates a light absorption peak at a given wavelength. To form openings in the conformal coating in alignment with the electrical components without damaging the components, a laser ablation tool may apply laser light at the given wavelength to the conformal coating. Openings may also be formed by placing tape over the components before the con form at coating is applied. The tape may have a color with a light absorption peak at the given wavelength to facilitate the formation of openings without damaging sensitive components.
