Abstract:
1. A method of manufacturing an electronic package module, the method comprising: providing a circuit board having a first mounting face and a second mounting face, wherein the first mounting face has at least one first encapsulation region and at least one first predetermined region, and the second mounting face has at least one second encapsulation region and at least one second predetermined region; mounting at least one first-type electronic component on the first mounting face at the first encapsulation region; forming a first dam structure at the boundary between the first encapsulation region and the first predetermined region; forming a first encapsulation at the first encapsulation region; forming a second dam structure at the boundary between the second encapsulation region and the second predetermined region; forming a second encapsulation at the second encapsulation region; forming a first metal shield layer at the first encapsulation region, wherein the first metal shield layer contacts at least one contact pad on the circuit board; forming a first sacrificial layer on the first metal shield layer; forming a second metal shield layer at the second encapsulation region, wherein the second metal shield layer contacts the circuit board; and removing the first sacrificial layer.
