Lead Free Rework |
Course
Objective:
After completing this course, trainees will be able to identify the main parameters of Lead Free rework, including associated materials and processes. The course will also outline the importance of proper heat transfer, and the consequences of numerous rework cycles. Trainees will also learn and practice proper rework techniques. Training will be given in accordance with IPC-7711 "Rework of Electronic Assemblies" and IPC-A-610 workmanship standards.
