Going green !!!!I have not seen anything on this topic on the forum, so should we disscus it ?. Everyone seems to be talking about it.let's tart with lead free (as this is an electronics forum). I have spoken many times on the subject, and all discussions lead to the same conclusion "it aint working".60/40 lead will melt at about 177 deg, lead free solder requires a much higher temprature. Virtualy all electronic equipment is now done in surface mount, the soldering is done by placing the PCB with components in place into an oven to allow the melting of the solder paste.Now at 177 to 200 or so degrees all is fine as most of the components are able to withstand the heat for the short time that they pass through the soldering process. Now with the soldering temprature almost double, the component failure rate is much higher, This means more rejects and therefore more waste (not so green).Where do we get lead form ? (out of the ground)... Where does it go when we dispose of it ? (back in the ground) !!!!!Recently, manufacturers have diposed of billions of electronic components just to meet the new reg's.What about us (the home constructors). What do I do with my stock of 1.5 million or so components ? "well I am hanging onto them".Now let,s move onto re-cycling...We are told that we should re-cycle all that we can (great idea).So how come I was told that I was breaking the law re-cycling my bottles.I will tell you, "answer:- you are a business and are not permitted to use re-cycling bins !!!Oh yes and I was threatened with a £400 fine if I did it again....Rite !! Carbon dioxide:- being blamed for ending the world, well maybe we should stop breathing and destroy all animals, that would reduce CO2.During war, explosives do more damage to the atmosphere than we are told.Has anyone stoped to think of other sources of CO2.... When you next open your nice cold can of beer or fizzy drink, think of what makes that nice refreshing hiss... Ah it is that nasty CO2, and considering that the the worlds biggest drinks manufacturer (you know who I mean), boast sales of 350,000,000 cans a year, that equates to a hell of a lot of CO2.....Don't get me wrong... There is too much waste in the world, and re-cycling is very important...Daniel.
