Abstract

An on-board computer includes a microprocessor chip with a lower face and an upper face, a chip carrier having an upper face on which the microprocessor chip is mounted, and a casing configured to discharge heat generated by the microprocessor chip in operation. An interposer is disposed between the upper face and the casing. The interposer diffuses the heat transmitted by the upper face of the microprocessor chip towards the casing. The interposer has an upper surface for heat exchange with the casing that is twice or more greater than the surface area of the upper face of the microprocessor chip. The interposer has on one or more sides a peripheral wedging rim coming into contact with a side wall of the chip carrier, and has no more than two peripheral wedging rims, in order to leave the other sides of the interposer free.
