Abstract: Embodiments of this application provide a chip and a manufacturing method thereof, and an electronic device, and belong to the field of chip heat dissipation technologies. The chip includes a die and a thermal conductive sheet. An active surface of the die is connected to the thermal conductive sheet by using a first bonding layer. Heat generated at a part with a relatively high temperature on the active surface of the die can be quickly conducted and dispersed by using the thermal conductive sheet, so that temperatures on the active surface are evenly distributed to avoid an excessively high local temperature of the chip, thereby preventing running of the chip from being affected.

Abstract: A circuit board assembly is applied to the field of electronic communications technologies to resolve a prior-art heat dissipation problem of a circuit board. The circuit board assembly combines, on a second circuit board, low-speed signals transmitted between a plurality of I/O modules and an IC chip, and then transmits the combined low-speed signals to the IC chip by using a low-speed cable. A low-speed signal sent by the IC chip to the plurality of I/O modules is extended to a plurality of low-speed signals on the second circuit board, and then the plurality of low-speed signals are separately sent to the plurality of I/O modules. This may be applied to a scenario in which a relatively large quantity of electronic components need to be disposed on a circuit board.
