RoHS benefits - Make it small!
There still seems to be quite a bit of controversy over the pluses and minuses of Europe's RoHS legislation (and the similar pending laws in California, China and other places) but I just ran across a benefit that I'd never thought of before.
Doctor Lasky, from Dr. Lasky's Blog interviewed some technical guys from Motorola about their new phone, the Motorola Q. It seems, according to the Motorola guys, that because the lead-free solder has different wetting and wicking properties, they can use smaller pads on the pc board then they could with lead-based solder. Doing so allowed them to cram more junk into such a small package.
Certainly a subject worthy of further study.
Help me. I'm mellllting.
