Abstract:
A printed circuit assembly includes a printed circuit board, a processor, an oscillator and a noise reduction device. The printed circuit board has a ground connecting portion. The processor is disposed on the printed circuit board. The oscillator is disposed on the printed circuit board. The noise reduction device includes a wave absorber, a blocking sheet and an electrically conductive member. The wave absorber includes a processor covering part and an oscillator covering part. The oscillator covering part protrudes from one side of the processor covering part. The processor covering part and the oscillator covering part respectively cover the processor and the oscillator. The blocking sheet is stacked on the oscillator covering part to cover the oscillator. One end of the electrically conductive member is connected to the blocking sheet, and another end of the printed circuit board is connected to the ground connecting portion.
