Lead-based solder used in atomizers??

[Droopy]

Guys, I just had a thought -- a thought that may have already been gone over ad-nauseum here (?) -- but since I am in the electronics field, I was wondering if there has ever been any tests done to see if the solder used to attach the nichrome resistance wire within the average atomizer (such as the Joye 510 or a njoy atty) has ever been tested/checked for lead heavy metal? [Lead solder is still extremely common in many parts of the world (except for Europe), so call me a worry-wort 8-o . FYI: We stopped using lead-based solder at our own consumer electronic's company here in the USA only just early last year…].

Anyone have any knowledge of this, or can site lead-solder tests on atomizers? (We just shouldn't assume RoHS COMPLIANCE from China...)

BTW, I am not talking about the lead paint tests that I have read here in this forum, but the solder used to construct the average atomizer (unless only pressure-crimping is used...)

There's mention of solder in the lead paint thread. Do a search thread for 'solder' and you'll see a few entries. eg.:

Thanks Kent. It was very nice (and probably expensive!) to have the paint in the attys tested, as presented by Sun Vaporer. However, the lab's test results were not in itself presented (that I could see), and the mention I read in that thread of there being no lead-based solder present (non RoHS) in the heating element itself was very vague.

So I wonder if there was ever any actual, confirmed report generated on tests performed on some common attys, and if any lead solder was detected in the atty's nichrome heating element? I just didn't see anything like that in that (long!) thread, but I may have missed it...

Looks like you just read the links words and didn't click on it or the link in the link... which is ok. Good luck.

@Kent is this quote from one of the threads ..what you are trying to get at... (I just quickly browsed..haven't had time to read into it @ work )

if you click on the arrow next to the quoted members name you should see images as well

An atomic analysis of the metal mesh and solder (XPS analysis),

ignoring carbon & oxygen content, i.e just the ratio of metals:





Metal Foam Mesh

99% Nickel

1% Tin



Pretty much a straight nickel metal foam as predicted.





Standard Solder (of a type I happen to have)

58% Lead

42% Tin







Silver Solder (of a type I happen to have)

80% Silver

10% Copper

10% Zinc







Lead Free Solder (plumbers, of a type I happen to have)

100% Tin







Atomizer Solder (after heavy heat cleanings)

83% Tin

7% Potassium

6% Silver

4% Nickel



Not sure if the potassium is just a surface contaminant, or a mis-identified peak.



Look like a type of cheap silver solder, & no lead which is good.



Should really do the last one again on a brand new atomizer

(when I have a need to dissect a fresh one again).





edit: the forum's fast & furious tonight, just posted this & it's on the 2nd page already!

yep... this part:

83% Tin
7% Potassium
6% Silver
4% Nickel

I thought I did, but perhaps I missed it? Wasn't it the link to the sophisticated test done on a single, older atty by exogenesis? Perhaps I missed the other reports (it's quite a long thread!)?

Thanks,

ADDED: Yes Kent, according to your new post to lightgeoduckit, it is the report I read. But do we really want to risk our health on one (albeit quite advanced) test done on a single, older atty? I think we are really fooling ourselves if we do...

I am leaving this thread in General... for the time being... and still deleting the other post... you should still get responses here.

it may be moved at a later time

Thanks

Well that was one example on that thread yes. There are others, I'm simply not going to link each one. There is another mention on the RofHS compliance, but with you're 'We just shouldn't assume RoHS COMPLIANCE from China...)' I don't see this going to far. I'm guessing you're going to have to research or test it yourself for your own satisfaction or perhaps just go back to analogs or whatever you were smoking before. I'm outta here.
