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.
