Effect Factors on Quality of Board Level Assembly

Assembly process is usually a most critical process for board level products,PCB and components are assembled together through SMT process.If the final test of the board level product does not pass,customers only blame the final assembly plant.In fact,the effect factor on the quality of board level products is not only the assembly process,but also component quality,printed board quality and processing technology.Introduce the effect factors on the quality of board level product and how these factors affect the quality of the product based on a case of metallographic analysis.
