Abstract
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.
