Circuit board assembly using metal plates as conducting medium embedded therein

摘要

A circuit board assembly includes metal plates to be used as conducting medium, an encapsulation enclosing therein the metal plates and provided with holes defined in the encapsulation to allow extension of the metal plates out of the encapsulation for electrical connection and electronic components securely mounted on the encapsulation and electrically connected to the metal plates to form a closed loop.
