Abstract
Embodiments described herein generally relate to an electronics assembly that includes a semiconductor device, a substrate layer, a first mesh layer and a second mesh layer. Jet channels that have a first inner diameter are disposed within the substrate layer. The first mesh layer includes a first plurality of pores that have a perimeter opening. The second mesh layer includes a second plurality of pores that have a second inner diameter. The jet channels, the first and the second plurality of pores are concentric to create a fluid path for a fluid to impinge a first device surface of the semiconductor device. The second inner diameter is smaller than the perimeter opening and the first inner diameter of the substrate layer such that a cooling fluid velocity increases when flowing from the substrate layer through the second mesh layer.
