- 1) Select and introduce a Pb-free board finish
- 2) Perform solder-paste evaluation and selection
- 3) Perform pilot builds using Pb-free boards and solder paste, but employ existing components
- 4) When Pb-free components become available, introduce them
- 5) Most importantly, start with smaller, less complex assemblies to gain confidence
- 6) Define your rework process. While the assembly is “mixed” (Pb-free paste and board, SnPb-plated components) SnPb wire can be used; when the assembly is entirely Pb-free, the rework process should also become Pb-free.
