An electronic assembly with phase-change material for thermal performance comprises a substrate and a semiconductor device mounted on the substrate. A sealed first thermal channel comprises a first evaporator section, a first fluid transport section, and a first condenser section. A phase-change material is contained in the sealed first thermal channel. The first evaporator section overlies the semiconductor device. The first fluid transport section extends between the first evaporator section and the first condenser section. The first evaporator section is spaced apart from the first condenser section. The first condenser section is in thermal communication with the heat sink.
