Tin-Lead Solder Health Hazards: Effects, Lead-Free Solder, & Safety Measures with 3M ABEK2P3 Mask

Hello

I would like to know how harmful is the harmful effect of soldering with lead tin? I have a 3M mask with an abek2p3 filter, but it is not very pleasant to work with, especially during longer sessions. I thought to go lead-free but unfortunately higher temperature is required and it is harder to recognize bad February.

I solder mainly with solder paste for several or several hours a week.

Can anyone comment on this?

Regards

Exactly ... now the question is how harmful are such doses? Should I work in a mask or is it enough to open the window above the workplace?

I do not want to underestimate the problem, but I know people who soldered with lead tin for several hours a day without a mask in a well-won workplace. For several dozen years.
They are retired, healthy and do not intend to relieve ZUS any time soon
It's a bit like cigarettes - statistically they shorten your life and / or cause serious diseases. See here: https://www.elektroda.pl/rtvforum/topic1247222.html#9851682

you scared me with this topic :D

I wonder if it is possible to somehow calculate how many, for example, a gram per day is a safe range, as long as we can talk about a safe range.

by the way, can it be soldered with lead tin, can products be sold and repaired or is it forbidden? he is not fully oriented in the EU directives.

The EU directive specifies the scope of equipment in which the PB-Sn eutectic alloy can be used. From what I remember, until the end of 2017. the PbFree standard will cover medical equipment, and there are also attempts at military equipment. In consumer equipment, it already applies to all products.
The change of alloy goes hand in hand with the technology of the housings and the methods of soldering them. Here we come to another problem, i.e. the change of technological habits related to the PbSn alloy so far. There are also some changes in the technology of covering the plates with solder mask and the geometry of the contact fields for individual housings. It's a lot of changes, but there is no advice.

The toxicity level of the PbSn alloy cannot be equated with the level of lead toxicity. The proportion of the alloy is so selected that it is possible to mix the crystals of one element with another. This means there are no pure lead precipitates. This in turn reduces the possibility of poisoning with this element. Fluxes and activators are more poisonous than the alloy itself. Considering the soldering temperature slightly increased by 15%, which is quite a lot. It is not by accident that if the smoke is acrid, the body thus points out that the environment is not the healthiest. It is worth considering the quality of the fluxes used.

Even the simplest portable extractor with a carbon filter will solve the frosting of the studio. Although when soldering in a small furnace, it is worth taking care of a solid permanent exhaust connected to the furnace.

None? The boiling point of tin is 2602 ° C and that of lead is 1749 ° C. Lead evaporates at about 600 ° C and does not appear to sublimate under normal conditions. I would be more afraid to inhale fluxes.

So theoretically, if something was done in lead-free and it broke and I will fix it using lead tin and I will have bad luck, I may have problems with it? Does using e.g. lead flux do the trick? because I read somewhere that you can outsmart the directive?

so when we are with fluxes, I will ask immediately because most often I use either Warton Brown Flux Jelly or Amtech NC-559-ASM-UV (TPF)


How do you rate their harmfulness during evaporation?

It's a very good news

You can't outsmart a directive this way. You're scheming in the wrong direction. Changes in the housing technology and the current load of the housing-PCB connectors will force you to use a lead-free alloy sooner or later. Compare both the thermal and electrical resistance of the PbSn and Sn alloys. In BGA housings, there is also an aim to reduce the amount of alloy, i.e. the size of the balls, and this is an irrevocable trend.
Do you have doubts? See what the motherboard of the lapopa looks like today and what it looked like 7 years ago, which is more or less when PBFree began to be introduced on a mass scale.

Don't pick yourself up on it. There are people who soldered gutters or other things with tin and lead all their lives, and they lived to see the beautiful eighty.

Oh. And how long do people who are employed in the production of lead batteries live? And I remember the times when telephone cables were in a lead tube.
I also know a situation where someone ate an organically grown tomato and was dead the next day. Anaphylactic shock or something ...
Lead is all around us. Even the so-called anti-corrosion paint red contains lead. Until you lick the painted elements, you will be safe. Well, unless lightning plays such an element, it adds inclusiveness.
All the talk about the harmfulness of lead is the same fucking thing that whoever had been doing five years in the states with asbestos when he came back the moment ended with cancer.

@ Kraniec_Internetów @ Spray Stonki not to forget about lead-sealed cast iron water pipes. Which we have, I think 50% in every major city.

Besides, there are copper CO installations in houses, they are soldered indoors and what? And nothing, people are alive and well.
The Sn-Pb alloy has always been soldered and I have not heard anyone die from it yet.

A cigarette smoker also dies from time to time, so are cigarettes harmless? In the past, people worked with asbestos and the effects were visible only after many years (not only directly in production, but also during assembly, but to a lesser extent). He reacts differently, but this does not mean that the threat should be taken lightly. I believe that the subject should be approached with a certain degree of caution and the statement that the insured is cautious always makes sense.

Once I was in the production of batteries, I caught so much lead dust in the air that there was flushed water on the floors so that the dust did not float ... (I had probably a week of sweetness in my mouth) All employees have to have a lead blood test every month and when you get close to the norm, you are released ...
You can also do such a test and everything will be clear.

The lead chelating agent from the body is sodium citrate contained in tin-flavored drinks. Although insiders, on the basis of long-term tests, argue that lead is best rinsed with booze and in second place with beer . It is also forbidden to drink tap water because, first of all, only animals drink water and secondly, it is unhealthy because some of the installations are made with lead. Why poison yourself when you can drink what is healthy?

Lead compounds do not rise during soldering. The tar substances we inhale are more dangerous. Lead is absorbed in contact with the skin and through the gastrointestinal tract (meals at work with unwashed hands that have come into contact with lead)
If we do not work in a plant where lead is smelted, this one is unlikely to hurt us.
The EU regulations are more about environmental protection and problems with the disposal of electronics containing lead. Lead compounds can appear on plants and herbivores. From these they find their way into our bodies.

Or the RF800 flux. This one can take your breath away.

Maybe I will ask, how many electronics do you know who got cancer from soldering with lead tin? The fact that these union madmen produce these types of laws and prohibitions is dictated more by their economic considerations (their desire to profit and keep a well-paid and warm job) rather than by concern for me or for you.

Personally, I have such prohibitions deeply in d ... Of course, you can forbid everything, because everything is in some way harmful and close it under a shade but ...

Well, actually the chemicals that they stuff us with on a daily basis, e.g. in food, are much more toxic. Do you know people who hurt them with their food? I know a lot of such people. I myself had a major bowel surgery 3 years ago. An interesting fact is that this is exactly what these Uniates are trying not to notice.

As someone wrote before, as long as you don't lick this tin, or what you're soldering, you'll be fine. If possible, solder with the window open. This is not even about tin anymore, but about fluxes, which can be used by your head :)

Wash your hands after finishing work.

I know! There were as many of them as the photographers who dabbled in their developers, or the farmers who inhaled nitro-chalk.
