  • Patent number: 11121110
    Abstract: A packaging process and a packaging structure of an electronic component are provided. By the packaging process and the packaging structure of the disclosure, the groove of the thermal conduction structure is covered by the first metal re-distribution layer. Therefore, the flank of the thermal conduction structure is easy to coat the conducting material. Moreover, because the flank of the thermal conduction structure is coated, the surface of the flank of the thermal conduction structure is difficultly oxidized. Furthermore, the conducting material between the thermal conduction structure and the board is flat, so that automated optical inspection of the packaging structure is easy to implement.

  • Publication number: 20190304961
    Abstract: A packaging process of an electronic component is provided. By the packaging process of the disclosure, the electronic component is grinded by the back grinding process. Consequently, thickness of the electronic component may be reduced to less than or equal to 50 ?m. The packaging process may achieve ultra-thin thickness and reduce the space of the power module. Moreover, the packaging process forms the contact pads with drilling process and grinding process without photolithography process. Consequently, the packaging process is advantageous because of lower cost and uniform thickness of the contact pads.
