Discussion About the Control of the Temprature Curve of Circumfluence Soldering

With the rapid development of IC electronics industry,it has become a new trend that the industry has the quality of a high level of integration and high reliability.In the promotion of this trend,SMT(surface-mount technology) have been further promoted and developed in China.Many companies have already introduce the SMT technology and the application of surface-mount components in the manufacturing and design.In SMT technology,circumfluence soldering is the core,because the defect of the PCB design,stencil printing and mount the components,will appear in welding.Therefore,if there is no reasonable and feasible circumfluence soldering technology,the technology control in front will have no meaning.
