Abstract: Manual soldering and cleaning processes are among the least controlled processes in printed circuit board assembly. As a result, they create special challenges to both quality and long term reliability. This paper describes some of those key challenges and provides ways to address them in assembly to minimize problems. The topics to be covered include: - Design Considerations - General Manual Soldering Recommendations - Material Selection and Qualification Criteria - Cleaning Recommendations - Process Monitoring and Control - Relevant Industry Standards - Case Study

Through awareness of the issues, proper design and appropriate material selection and process control, companies can successfully use manual soldering and cleaning processes in high reliability products. Without proper planning, however, these processes can lead to a path of ruin.

Key Words: 

manual soldering, hand soldering, manual cleaning, spot cleaning
