    摘要: Example embodiments of the present invention include a printed circuit board (PCB) capable of controlling the size and position of voids during a surface mounting process. To this end, the PCB includes: an insulating plate made of an insulating material; printed circuit patterns formed on the insulating plate; a plurality of lands to support a plurality of solder joints, each land coupled to one end of each of the printed circuit patterns; and anti-wetting layers mounted on a surface of each of the lands for solder joint therein. The anti-wetting layers allow a void produced during a surface mounting process to move to a central surface on a pad, so that the solder joint reliability between the solder ball and the land is increased. As a result, the reliability of a semiconductor device is enhanced.

    摘要: A semiconductor module includes a base plate, a circuit substrate coupled to a side face of the base plate, a first semiconductor package mounted on the circuit substrate and a radiation channel portion inside the base plate. The radiation channel portion includes at least one heat pipe containing a working fluid. The at least one heat pipe containing the working fluid is configured to transfer heat generated by the first semiconductor package. Thus, the radiation channel portion may provide an efficient and reliable semiconductor module having improved heat transfer and radiation performance.
