温度曲线的定制化分析和管理（Customized analysis and management of temperature curve） Customized analysis and management of temperature curve 2008/11/25 The temperature curve (Profile) is SMT welding most common process parameters, the temperature time curve in a sense almost all characterization of SMT welding technology, from reflow, wave soldering and rework to have to use it. The reflow temperature curve (ReflowProfile) is the most widely used and widespread. The reflow soldering technology of SMT is a chemical and physical process that combines the temperature resistance of components, the thermal characteristics of components, and the characteristics of solders. For this type of results (such as: the reliability of solder joints, strength etc.) cannot directly determine the special process, process control becomes important, while the temperature curve is a process engineer, quality engineer to determine this complex process is correct, reliable and controlled important basis. This shows the importance of temperature curve in SMT welding process. For a high quality assembly process, process engineers will develop specifications for each products temperature curve, and ensure the quality of the final product through routine quality monitoring. However, as SMT products become more diversified and complex, more and more temperature curves also bring challenges to process management. The current temperature profile analysis software are attached to the temperature curve corresponding to read, display, analysis, report output and even some of the functions of SPC software, but few in curing limited%26ldquo; normal%26rdquo; data type has been unable to meet the increasingly fine differentiation, personalized products for the special requirements of temperature curve moreover, more and more users hope to other key%26ldquo in the process of welding input;%26rdquo; information, such as component information, equipment information, information also include solder, so the temperature c
