Description
technical field [0001] The invention relates to the field of printed circuit boards, in particular to a printed circuit board embedded with phase-change heat dissipation components. Background technique [0002] As electronic systems become smaller, more functional, and more efficient, in order to meet the continuous improvement of the electrical performance of electronic products, PCBs carry more and more passive and active electronic components. Large-scale integration of components brings high power consumption, resulting in increased power density of electronic systems. If the heat cannot be dissipated smoothly, the junction temperature of the components will rise sharply, which will seriously affect the reliability of electronic equipment. [0003] On the other hand, when the power of the power device gradually increases, the Joule heating on the power transmission line on the circuit board becomes very significant due to the increase of the current. In particular, hi...
