红外再流焊接设备及工艺改进探讨

Discussion on the Design of Infrared Reflow Welding Machine and Technology Improvement

通过对已研制出的国产红外再流焊机整体设计的分析、试验,以及对国外同类产品的调研,对SMT产品常见的缺陷进行分析,探讨在焊接环节导致缺陷的原因,研究SMT焊接工艺技术,从加热元件选择、结构设计、温度控制等主要方面提出对已有的国产红外再流焊机设计的改进措施。

Through the analysis and experiment of the infrared reflow welding machine developed and the study on the similarly device produced overseas, the defects appeared frequently in SMT product are summarized, the reasons which caused the defects in welding course are discussed. From the study on the welding technology of SMT, we can improve our infrared reflow welding machine on the aspects of calefaction element selection, structure design and temperature control, thus raise the success ratio in the first process.
