Provided in the present application are a board-
level structure, a device and an electronic apparatus. The board-
level structure comprises a second substrate and at least one first device. The first device comprises a first body and a first substrate, a first
welding spot and a second
welding spot being provided on the first substrate, and the first substrate being connected to the first body by means of the first
welding spot. The second substrate is provided with an
accommodation portion and a third welding spot, the third welding spot being located on the second substrate and close to the
accommodation portion, and the first substrate being welded to the second substrate by means of the second welding spot and the third welding spot. The first substrate spans over the
accommodation portion, and at least part of the first body extends into the accommodation portion. The present application uses the accommodation portion to accommodate part of the first body in the Z-direction, thus reducing space occupation; the first substrate can be directly welded to the second substrate by means of the second welding spot and the third welding spot, thus the first substrate can be connected simply by forming a pad on the surface of the second substrate in one process step, thereby simplifying the
assembly process and ensuring assembling quality.
