Erik:
Why, oh why, is it so difficult to get IPC and the industry in general to back pragmatic recycling rather than the cosmetic "feel good" nonsense of removing lead from solder? Recycling attacks the lead pollution problem. Taking lead out of solder merely
shifts the pollution burden to other metals and other geographic regions.
Well done, sir.
