Patent ID: 8279607

Claim:
A cooling module assembly method comprising: forming at least one through-hole on a circuit board; coupling the circuit board to a heat dissipating unit so that a face of the circuit board is coupled to a coupling face of the heat dissipating unit; filling the at least one through-hole with metal solders; fixing at least one heat-generating element to another face of the circuit board, wherein the at least one heat-generating element aligns with and covers the at least one through-hole; and melting the metal solders filled in the at least one through-hole while the circuit board is coupled to the heat dissipating unit and fixed to the at least one-heat generating element to directly connect the heat-generating element to the heat dissipating unit during a single round of melting, wherein coupling the heat dissipating unit comprises hooking a plurality of hooks of the heat dissipating unit with a plurality of buckling grooves of the circuit board.
