Good article, thank you for the URL.

The best solution for anybody making stuff that has to work for many years (industrial, etc) is to try to classify the product as "control and monitoring" and carry on using tin/lead. Many companies have done this.

Stick ROHS stickers on everything; that's what the Chinese do, the stickers are now found on every box that comes out of there, regardless of contents.

It's like CE marking was 10+ years ago. Everybody went berserk, then the fuss died down. Now, everybody has "CE" on the product, nobody cares and *almost* nobody asks you for the supporting documentation.

The whiskers issue is probably OK with normal SMT components with generous joint spacing, say 1mm or more. TSOPs are going to be a major problem...

Question: ROHS has been around for a while now. Besides the Swatch case, has there been a compilation of quality before versus after ROHS published somewhere?
