Manufacturability design is to consider factors such as manufacturability and assemblability of the product at the design stage, so that the product is manufactured with the lowest cost, the shortest time and the highest quality. DFM is the core technology of concurrent engineering. We realize the synchronous simulation of the design process from design, platemaking to assembly by manufacturing the simulation system. The design method based on DFM concept can effectively reduce the trial production times and speed up the research and development cycle. In other words, more problems should be considered in the early stage of design, which is the key to guarantee the success of one-time trial production of PCB design.
