I know from hand-soldering some stuff using the unleaded stuff in a cold garage this winter, that it's a really pain the neck. You can hold an 800F iron on a piece of solder and just about get it to melt when ambient is ~30F, but then as soon as you touch the molten solder to anything (component, wire, board, some slightly colder air...) it immediately re-solidifies. It was miserable. I think one side- effect of the RoHS regulations is going to be a huge increase in the use of space heaters, leading to a marked increase in fossil fuel burning in order to make the garages/solder shops of the world a little warmer. Toxic landfills or greenhouse gasses: take your choice Europe ;) C |
