返修工作站用于小批量BGA的高质量焊接

摘要

With the development of electronic technology, BGA devices have been widely used in spaceflight and military industry and other fields. In this kind of short-cycle, low volume and multi-species production, using rework station is a more economic and effective way to solder BGA devices than that with automatic surface mounting machine. Discuss the process of soldering BGA device with rework station and the matters needing attention. Check the soldering quality with X-ray and metallurgical microscope. Provide a new way to solve the high quality soldering of BGA device in small batch production .%随着电子技术的发展，BGA器件在航天和军工等领域也得到了越来越多的应用。在这些小批量、多品种的场合，使用返修工作站是比自动贴片机更为经济高效的BGA焊接手段。重点介绍了使用返修工作站进行BGA器件焊接的工艺过程及注意事项，并对焊后的器件进行了X光照相和金相试验效果验证，为小批量电子单机生产中BGA器件的高质量焊接提供一条新思路。
