The current invention comprises a base plate made of at least a first metal and a second metal clad together with a metallurgical bond, where the first and second metals are different metals. The base plate includes an enhanced surface that is entirely contained within the second metal, where the enhanced surface comprises fins, pins, or other structures. The tip of the enhanced surface extends above the outer surface of the second metal, and the enhancements are monolithic with the second metal. The base plate can form one component of a cold plate for cooling electronics.

Method of producing an enhanced base plate

A substrate for electronic components is formed by bonding a cooling metal layer to one side of a ceramic tile and bonding an electronic metal layer to the other side of the electronic tile. The substrate is secured to a machining base and the cooling metal layer surface is enhanced through an MDT process. In the process, fins are sliced into the cooling metal layer with a tool to a depth of less than the cooling metal layer thickness. The slicing forces material upward without removing material from the cooling metal layer, forming fins that extend beyond the original thickness of the cooling metal layer. The fins can be cross-sliced at an angle to form pins.

Method of producing electronics substrate with enhanced direct bonded metal

A cold plate is manufactured by obtaining a base plate with a top surface, a bottom surface, and an edge. An inlet trough and an outlet trough are machined in the top surface. Fins are cut into the base plate with a tool that contacts the base plate in either the inlet trough and the outlet trough and then exits the base plate in the other of the inlet trough and the outlet trough. An inlet nozzle indent is machined from the inlet trough to the edge of the base plate, and an outlet nozzle indent is machined from the outlet trough to the edge of the base plate. A cover covers the inlet and outlet nozzle indents, and an inlet nozzle and outlet nozzle are secured to the inlet and outlet nozzle indents.
