Lead solder is not yet banned in the US. But it is banned in almost all the world. The US is not the biggest user of solder and few companies want to make a US-only product so we get what is available on the world market. But you can still find lead solder. But I've 100% moved on. The best stuff is silver based now. Use that.
Not always. Old equipment needs to be worked on with older kind of solder. If nothing else it is to preserve the artifacts in museum(s). Silver is harder to work with because of the temperature difference so PCB would get damaged before the solder joint would be complete.
The reason they have banned lead is that EVERY electronic device eventually ends up in a land fill. The lead then leaches into the water table.
Not exactly true!!!
Sounds silly that tiny phone might contaminate an entire aquifer but Apple sells something like five million phones every month and now that the market is started this means 5 million phones go into landfills every
that is unlikely. People do recycle stuff these days. Manufacturers are taking back old equipment for recovering precious and other metals that can be used in manufacturing again.
We have scrap metal and electronics collection in place here in Silicon Valley. Every few months recycling specialists pickup anything of that sort left in our driveways with attached note. They don't dump it in landfills.
month. Or another way to think of this is that EVERY pound of lead solder manufactured eventually goes to a land fill. Lead is mostly not to harmful to older adults but has a serious effect on babies and children and the effects of exposure can't be removed, the effects are permanent. They passed a law years ago in China that ALL phones must use USB chargers with a standardized USB-A connector. Notice that the entire world is now
Any such laws come from CA in US first as far as I know. China keeps polluting their sea and that can be traced across Pacific to US West coast. Watch nature programs that show pollution affecting animal world on the way.
following China's charger regulations. The effect is millions of tons fewer used chargers in landfills. Now that chargers are standardized people keep them. China got that one right.
China is the last one to be given credit for cleaning up the environment based on what I see on Asian TV programs alone. Japan, S. Korea care about the environment way more than red PRC.
About freight for stuff on eBay. Most of what I buy there is with free shipping. The free shipping is mostly from items shipped from China as postage is very low there.
That postage is subsidized by USPS based on some old obscure law that was put in place to help undeveloped countries I heard.
