  • Publication number: 20230146529
    Abstract: The present disclosure is related to an electronic module assembly structure including a system board, an electronic module and an adhesive material. The system board includes a first upper surface and a first lower surface opposite to each other. The electronic module spatially corresponds to the first upper surface and includes plurality leading pins and a carrier. Each leading pin has a soldering surface and is connected to the first upper surface through a first reflow soldering process. When the plurality leading pins are connected to the first upper surface, a height difference is formed between the carrying surface of the carrier and the soldering surfaces. The adhesive material is disposed on the carrying surface or the first upper surface. The carrier is connected with the first upper surface through the adhesive material, so that the electronic module is fixed to the first upper surface through the adhesive material.
