Scope: This standard is based on the FMEA analysis method, sorts out the preparation process of graphene thermal conductive films, analyzes the technical requirements of thermal conductive films for graphene materials, and explains the impact of various technical indicators of graphene materials on the film preparation process and film performance. It also provides optimization practice cases of film preparation. This standard is applicable for enterprises or scientific research institutions to provide reference when establishing DFMEA for graphene materials and PFMEA for graphene thermal conductive films; Main technical content: With the widespread application of 5G technology (fifth generation mobile communication technology) in industrial and consumer electronics fields, and the increasing integration and miniaturization of electronic components, the performance of core computing components continues to improve significantly. The well-known 10℃ rule points out that the reliability of electronic devices is closely related to temperature. When the temperature is 70℃~80℃, its reliability decreases by 50% for every 10℃ increase. Therefore, heat dissipation technology has become an important aspect that cannot be ignored in the reliability design of electronic devices, and the development of membrane materials with higher thermal conductivity has become an urgent need in the electronics industry. Single-layer graphene is the material with the highest theoretical thermal conductivity discovered so far. Compared with traditional artificial graphite thermal conductive films, graphene-based thermal conductive films have the advantages of high theoretical thermal conductivity, adjustable film thickness, and flexibility and bend resistance. Importantly, graphene materials are independently controllable in terms of resources and have become one of the popular materials for thermal conductivity in the current market. Graphene thermal conductive film enterprises are emergi
