  • Publication number: 20100265671
    Abstract: The package structure of the PCB comprises a substrate and a frame. The frame is located at the top of the substrate, and the substrate and the frame define a receiving space. The electronic components are mounted on the substrate and distributed in the receiving space. Because of the protection of the frame, the electronic components are effectively protected from the collision of installation in the process or use in the process. The substrate can be a flexible circuit board or a rigid-flex PCB and the electronic components are directly embedded in the substrate. Therefore the thickness of the package structure is reduced.
