Hi Terry,
The materials under these slash sheets may or may not be 'RoHS-compliant', 
but with the exception of /99 they are not 'RoHS-capable'. That means that their 
STII (Soldering Temperature Impact Index)-values are too low. /99 gives a 
minimum STII of 202, which would make that material of limited usefullness for 
lead-free soldering processes—there are however materials under slash /99 that 
have higher STII values.
For more information—a lot more information—you should be getting my White 
Paper: "Recommendations for PCB FAB Notes and Specifications in Printed Circuit 
Board Drawings for SnPb and Lead-Free Soldering Assemblies, the Qualification 
of PCB Shops and Activities to Assure Continued Quality."

Werner
