Prototype assembly refers to assembling electronic and mechanical components from various parts into a complete prototype product. This not only includes the installation and welding of electronic components, but also the assembly of mechanical parts such as casings, connecting wires, buttons, etc. Prototype assembly is a complex process that requires multiple skills and experience.

　　In the prototype assembly process, the first step is to ensure the quality and compatibility of all components. Next, according to the design drawings, gradually assemble the various components together. During this process, some adjustments and modifications may need to be made to ensure that the final product works properly and has a good user experience. After assembly, a series of tests are required, including functional testing, performance testing, and reliability testing, to ensure that the product's various indicators meet expectations.
