Abstract:
An electronic assembly comprising:an electronic substrate having upper and lower surfaces, a plurality of metal lines therein to transmit signals, a plurality of contact pads on the upper surface thereof and electrically connected to the conductive lines, and a cooling opening therethrough, the cooling opening having an inlet to allow fluid into the electronic substrate, a section in the electronic substrate through which the fluid flows from the inlet, and an outlet from which the fluid flows from the section out of the electronic substrate; and a semiconductor assembly mounted on top of the electronic substrate, the semiconductor assembly having upper and lower surfaces, a semiconductor die having an electronic circuit, and a plurality of electric contacts on the lower surface thereof, the electronic circuit being connected through the electric contacts and the contact pads to the metal lines so that signals are transmitted between the electronic circuit and the metal lines, operation of the electronic circuit causing heating of the semiconductor die, heat being transferred from the semiconductor die through the contact pads and the electric contacts to the electronic substrate from where heat is transferred to the fluid flowing through the section.
