Claim 12:
13. A method for assembling a printed circuit board (PCB) system, comprising:
mounting an integrated circuit (IC) package to a first PCB to electrically couple first contact structures on a bottom surface of a package substrate of the IC package to the first PCB, the IC package including a main IC chip;
stacking and aligning a memory module on the IC package, the memory module comprising i) a second PCB, ii) one or more memory IC chips disposed on the second PCB, and iii) second contact structures disposed on a bottom surface of the second PCB;
disposing an interposer between the second contact structures disposed on the bottom surface of the second PCB of the memory module and third contact structures;
electrically coupling the second contact structures disposed on the bottom surface of the second PCB of the memory module to the third contact structures disposed on a top surface of the package substrate, including interconnecting the second contact structures of the memory module with the third contact structures disposed on the top surface of the package substrate via the interposer; and
coupling a heat dissipation member to the main IC chip to dissipate heat from the main IC chip away from the one or more memory IC chips.
