As the popularisation of electronical devices, the development of micro systems has attracted the attention of the researchers. Therefore, it is crucial to identify the effects of relevant parameters in micro forming process. This study mainly focuses on the impact of holding time in heat treatment process on the properties of Cu-Al-Cu laminate composite materials during micro deep drawing process. The results demonstrate that the Cu-Al-Cu laminate composite material that experiences 10-minute holding time can obtain better properties. Furthermore, a simulation model of the micro forming process is developed and the simulation results are compared with the experimental ones.
