Weigh In on the Lead-Free Soldering Consensus Topics

Folks,

Some time ago, I mentioned that I was working on a consensus of the status of lead-free/RoHS
compliant assembly. My hope is to find data and facts that will support the consensus. I am making progress, but at this time I would like to share the subtopics in the consensus. Look them over and see what you think:

1.       Was/Is lead-free electronics/RoHS needed to protect the environment?

2.      Is lead-free solder easier and safer to recycle than lead-containing solder?

3.      How has the increased use of tin and silver affected their supply and price?

4.      How much did it cost to implement lead-free/RoHS compliant electronics?

a.      What is the cost adder to a typical lead-free product?

5.      What are the process challenges of lead-free assembly?

a.      Are these challenges being addressed?

b.      If so, how?

6.        What is the reliability of lead-free vs leaded electronics for commercial applications?

a.      E.g. 0C to 100C thermal cycle, drop shock

7.        What is the reliability of lead-free vs leaded electronics for harsh environment/military applications?

a.      E.g. -55C to 125C thermal cycle, other Mil stress tests

8.      What is the threat of tin whiskers, tin pest and other similar lead-free related reliability phenomena?

9.      What is the status and need for halogen-free assembly?

 

Help me by suggesting topics that I have left out.
