Harmful Effects of Lead in Soldering Tin: Breathing Difficulty, Alternatives & Tips (ZD-153A)

Hello! For some time I have been feeling more difficult breathing after soldering, maybe even silting, etc. I've been soldering maybe 2-3 years, something like this. I am ventilating the room, recently I bought a tin fume extractor (smoke) zd 153 a. It is average but something helps . I heard that lead in tin is harmful, would lead free tin be better? But where to buy one? I use such a cheap soldering iron without a station. Would a transformer be better? My point is that it does not heat all the time and it does not keep blowing smoke, for example, burning rosin in the grotto. And is there anything healthier than rosin with a similar effect? Best regards and sorry if I wrote something wrong or posted it in the wrong place .

lead (disease) manifests itself after 20-30 years, and there is no respiratory manifestation.

There is a lot of inaccuracy in what you write. Put the word "placebo" on google. Don't get bogged down by some conspiracy theories off the net.

IT IS IMPOSSIBLE for you to feel the effect of less lead after purchasing the absorber. (Of course, the absorption of smoke from the organic parts can be felt as an improvement in comfort)

And many consider the pressure with lead-free tin to be anti-ecological, because devices are thrown out much faster.

PS. if rosin smoke is harmful to you, remember never eat sausage from the fire

Sn-Pb alloy is the most harmful for equipment manufacturers, and the most different for managers who have never had solder in their hands.
In the case of respiratory symptoms, I would be more interested in flux. It is its vapors that are released during soldering and enter the respiratory system.

Good evening.
This damages the flux in the binder, not the lead. I propose to buy a solder from a good manufacturer and there will be no problems. I used to have the best solder from the OMIG plant. I got two spools of solder with a diameter of 0.7 or 0.9 mm I don't remember exactly that anymore. The bobbins were orange. It soldered excellently, the flux smelled of incense - very pleasant. Solders with this flux allowed for soldering even to slightly passivated printed circuit boards. In OMIG it was used for the production of quartz resonators. Solder was put into the quartz stand and a new silver cover was put on it. Another advantage of solder with this flux was the fact that it was not aggressive towards non-ferrous metals and had a very nice spread (shape), which was important for the final product. Later, when the solder "came out", I used tin-lead solder with TLR-157 flux. I soldered a lot for several years, assembling modules to order, so that I managed to solder a lot of kilograms.

I use tin from CynEla, which is so typical. So is she bad? Will you give any links to the better ones? greetings

Added after 4 [minutes]:

My tin which I use Tin 1.00 / 100g / binder LC60-FSW26

If you don't solder 10 amps a day, you don't need better tin. What you have is regular SN60 alloy. I solder this alloy all my life, I keep solder in my mouth and nothing happens to me. You don't eat that lead.
Rosin smoke can be harmful, but not so bad that it makes you feel breathless.

The type of soldering iron also does not matter. Whether a short circuit or a resistor, something will always be smoking.

If you do experience such sensations, either you are oversensitive to the propaganda or you have pulmonary problems.
In this case, it is worth checking with a specialist before you buy "better" tin.

Good day.
I was able to find a spool of solder I had from OMIG. There is Soudure Tinea. There are other ones, but after years of using this spool, they are unreadable
Searching in Google brought me here http://fr.farnell.com/multicore-loctite/3096525-m/soudure-60-40-hi-act-0-5mm-250g/dp/5090787 and here is a pdf description http : //www.farnell.com/datasheets/1683971.pdf. There is only one drawback - the price is prohibitive for us.

There is a rumor that lead-free solder has more harmful flux fumes, because the temperature is higher and they use other fluxes, I don't know how much truth is in that.

In general, the flux in the binder is to dissolve oxides and reduce surface tension, not to smell it, and rather no manufacturer makes a flux safe for health, they write in the safety data sheet that flux vapors should not be inhaled, and that's it. Regardless of whether it smells good or bad.
The harmfulness is completely independent of the olfactory sensation, as is the case with poisonous mushrooms which are tasty.

Workers employed in soldering on a daily basis suffer from respiratory diseases, but not immediately.

Rosin also gives off harmful fumes:

Its natural origin does not change anything here, of course, it is activated more aggressive both for oxides that hinder soldering and for the lungs

In my humble opinion, there is no point in crushing the copy - rosin (its fumes as a result of strong heating) cause an allergic reaction in SOME people and that's it. Some. Some people experience this reaction from the first time they come into contact with the vapors, others show years later, and still others never.
The fact is that every producer has different flux compositions (in the case of Multicore there was even a tin that had a different flux in each of the six channels and only their combination during soldering gave an effect) - from natural resin derivatives (rosin) to difficult to define "chemistry" ". It is also no secret that lead-free tin has fluxes much more aggressive than ordinary "lead". Moreover, lead-free tin comes in various forms (with various additives of various - not only silver - metals) and each of them requires a slightly different composition of the flux.
Asthma also comes in many varieties - only one allergen can sensitize, and maybe none (atopic asthma, where the allergic reaction is triggered spontaneously).

The solder to which the links refer, its price is not too high, it is acceptable due to the soldering temperature (not to be confused with the melting point). In the times of OMIG, semiconductors were based on germanium, the construction of the transistor could not stand the temperature higher than 200 ° C, special tweezers were used to remove heat from the terminals of the elements.
Currently, for the outlets of complex processors with a very dense raster, SMD Chip Quik solder wire is used, probably it is Wood's alloy (bismuth, lead, cadmium and tin) the price is about 20zet for 10cm https://www.youtube.com/watch ? v = 7kyaz4Zrd78

you'd better do your own research because after 3 years of soldering, you shouldn't be fine, I've been in it for over a dozen years and I don't feel anything.

I love how electronic engineers stubbornly give up that their work has any impact on health. "I took the tin in my mouth, I have been working for 20 years and I'm fine"
I wonder if a welder was asked if his eyesight deteriorated with age, or if he had a garbage collector, if he had any mycosis / skin lesions, if he had a disease with pneumoconiosis, etc., they would also defend their profession so fiercely.
If you had an identical twin brother who spends these moments actively while you solder, I wonder how many years you will live to see, and how many years he will live to see.

Since I bought the smoke extractor, I can see how much the filter in it changed its color from black to white from the flux smoke. Or like a pump membrane from an electronic suction device, despite the presence of three filters, it requires cleaning from time to time because sticky flux dust accumulates on it.

The matter is simple - you inhale this sourness (even if it is 1% of what comes out of the heated tin), it builds up in your airways and lungs, and it's not something your body can easily neutralize.

I do not solder much, but I can see the difference that when I did not have a smoke absorber, in the evening after 2-3 hours of soldering I was croaking, now it is better.

Thanks for such a great interest in my topic . There is also one thing that it is possible for me to convince myself of it. I am quite susceptible to such things, but I don't know. As for the absorber, I have a number of 153 and it still works on average, about half of the tin is not absorbed and the smoke that comes out is not perfect. I don't solder much, I would say little. Greetings!
