摘要
焊膏印刷是表面组装技术的核心工艺,其加工质量关系到元件贴装、回流焊及产品整体性能。介绍了焊膏印刷工艺,着重分析了影响印刷的焊膏、模板、刮刀等因素及工艺控制要点,对常见问题给出了解决措施。
Solder paste printing is the core technology of surface assembly technology, and its processing quality is related to the mounting of components, reflow soldering and the overall performance of products.The process of solder paste printing is introduced. The factors affecting the printing process, such as solder paste, template and scraper, and the key points of process control are emphatically analyzed. The solutions to common problems are given.
