Printed circuit board assembly

摘要

A printed circuit board assembly includes a printed circuit board, a first heat dissipating module, and a second heat dissipating module. The printed circuit board includes a first heat generating element and a second heat generating element. The first heat dissipating module is disposed on the first heat generating element. The first heat dissipating module includes a heat sink and a first heat pipe. The first heat pipe includes a pipe body and an extending portion extending from the pipe body. The second heat dissipating module is disposed on the second heat generating element. The pipe body is connected to the heat sink and the extending portion is connected to the second heat dissipating module.
