The quality and reliability of SMT processing products of PCB assembly mainly depend on the manufacturability and reliability of components, electronic process materials, process design and assembly process. In order to successfully PCB assembly products, on the one hand, it is necessary to strictly control the quality of electronic components and process materials, that is, incoming material inspection; On the other hand, the manufacturability (DFM) of SMT process design must be reviewed for the assembly process. After and before each process in the implementation of the assembly process, the process quality inspection, i.e. surface assembly process inspection, includes the quality inspection methods and Strategies of each process in the whole assembly process, such as printing, patch, welding, etc.
