content: Hello,when watching repair videos on YouTube for example from Louis Rossmann or NorthridgeFix i see they are still using leaded solder for fixing notebooks, tablets and so on.I thought usage of leaded solder is not allowed anymore. Are there exceptions in regulations for repair? And are regulations different in the EU and US? I wonder if we could use leaded solder for repair of electronic equipment as well in the EU.

content: It is your equipment, you can do whatever you want. Same thing with hobby projects. Leaded solder is not outlawed, it is available and some industries still use it even in mass production for reliability reasons.The goal of the regulation is to reduce the use of lead in mass production. The amount of leaded solder a repair shop would use in a lifetime is meaningless, it literally does not matter.

content: Quote from: ataradov on September 30, 2022, 06:05:56 pmI beg to differ. There is not just one repair shop but thousands and all of them using leaded solder does at up to a significant source of lead contamination. Louis Rossman should use unleaded solder for equipment that goes into to field (the hands of consumers) like anyone else.

content: Only tiny percentage of the manufactured devices go for repair. And repair shop modifies a tiny part of the board. The amount of solder they use even if combined is tiny compared to the amount used for manufacturing.You can dick around with formulations all day long, but leaded solder is still unbeatable for manual soldering.

content: Not sure what Louis is using today. I thought in an older video he mentioned that he used leaded on this particular repair. And even in his online store he has leaded solder as affiliate link to Amazon.But finally my question comes down to professional repair in the EU. I thought RoHS directive prohibits the use of leaded solder. Is that correct or are there any exceptions for repair? So if i do some repair here and there as a part-time job i assume i can not use leaded solder? I mean unleaded is fine for most things. But sometimes it would be easier to use leaded for really tiny stuff.

content: Lol, that amount of solder accounts for maybe... 0.0001% of the solder used in the product. Usually its like a cap repair or somethingThink about this:1) risk throwing away entire device because of some trace de lamination that occurs on a 12 layer PCB because of excessive heat (those boards are practically one time use). Factor in all the other costs associated with telling the customer that you broke their stuff. Thats about a pound of e-waste generated.2) tolerate a few milligrams of lead.Its not plutonium.The amount of energy saved by reducing the demand for manufacturing demand for even more phones to end up being burned in Africa totally covers all the downsides of using lead.How about you go after lead on historical building roofs? It's actually alot compared to the amount of lead used in many years of equipment repair, and its still considered basically nothing.I am telling you that there is so much more hidden lead being used in all sorts of industries that ends up polluting stuff that this is a absolute waste of time to consider.here is one, how about you go after lead acid batteries instead. Thats like going after a match stick burning when there is a whole city that is in conflagration. One incorrectly disposed LA battery (not counting stuff like lead contaminated acid leaks that get on the road) probobly equivalent to many years of SMD caps being replaced in every repair shop in the world. A boat that sinks? A car crash that ruptures the battery and scatters it ? You are talking pounds every time, tons of crumbling lead oxide dust, etc. And lead acid battery is just one of them.Hell, tons of old cars are soldered together with lead thats slowly disintegrating along the roads as well (used to be a way to attach the roof of a car).And then you also create a industry of high precision soldering tools that is bound to be extremely wasteful when people try to figure out a way to get lead free to work right for shitty consumer item repairs. Why build tools that you don't have to? I can imagine all sorts of efforts going to making all sorts of crazy shit to replace 10 miligrams of lead on a SMD capacitor reliably. Easier repair = less waste. The amount of general industrial waste that won't be produced if you reduce yearly electronics demand by 10% (facilitated by easy repairs) is extremely large. If people start getting the idea that your average repair shop is gonna fuck up the repair (they already have a bad reputation!), you will just have more people saying fuck it and buying a new phone, laptop or videocard. It's setting up the repair industry to fail.Look at the pakistani car battery repair industry (and their practices) and you will see that going after a phone repair shop is justpreposterous. (tldr, they do open air casting of lead plates in the desert with high wind and dry conditions, it must spread lead dross everywhere within 1000 miles lol, ). And don't fail to consider coal and stuff, which ends up making lead vapors from operations. by tightening down emissions regulations for mineral based industries you already have a sea compared to the drop. For instance dust control on open air mines (they leave heavy metal laiden dirt on top of the ground), coal processing, minerals processing water (you get lead compounds in the wash water), land reshaping projects, etc. Probably tons of lead contaminated industrial water are mixed with normal water every day also post discharge (try to ensure that all water extracted from the earth is drinkable, and do not allow for 'industrial grade' water to be used.. good luck doing this in some places, you have special water sources that everyone knows you cannot drink).

content: Quote from: Domitronic on September 30, 2022, 05:49:48 pmAs far as I know, ONLY the EU has actually restricted lead solder (under RoHS). The reason the whole world switched is that it’d be uneconomical to make separate lead-free versions of things for the EU and leaded for everyone else. It’s cheaper to just make it all lead-free.In USA, do what you want. (California requires a warning on products with lead, but doesn’t ban them outright, IIRC.)In Europe, you can use leaded for repairing devices originally manufactured with lead solder. But due to a separate law (REACH) it’s difficult for European consumers to purchase lead solder. (Businesses are allowed to.)But I have said many times: lead-free isn’t anywhere near as bad as so many people make it out to be. From their hysteria, you’d think it made soldering practically impossible. That’s simply not the case. In my experience, the quality of the flux makes a bigger difference than whether it contains lead. And yes, some lead-free alloys are better than others, and surprisingly, the ones with the lowest melting points are not the ones that are the nicest to work with. (The nickel-germanium-doped tin alloys like Sn100+ flow nicely and produce good looking joints.)If you’re soldering (or desoldering) at the very limits of what your equipment and technique can manage with lead solder, then the added heat needed for lead-free can push you into failure. But with proper equipment and technique, lead-free works just fine.

content: As others have mentioned, the amount of lead on a repair shop is minuscule compared to other sources of lead "in the wild". I don't worry about it.As tooki mentioned, lead free is not as bad as it once was, but it is still worse than leaded, especially in large mass areas where it can get very brittle depending on the age and/or mechanical stress. Or in small components where the higher temperatures can potentially cause more damage to the parts.One aspect rarely mentioned is that, regardless of leaded or lead free, the volatile compounds of chemicals surrounding the process (type of flux, tip cleaner, which are much more needed when using lead free) worry me much more than the lead content. Those fumes are nasty (and we have filters), but I suspect these don't get anywhere near the attention they deserve in this discussion.

In the NL a law is in the making banning lead piping from some existing buildings (like rented homes) and thus requiring replacement of lead pipes.

The sensation of a PCB should bring fear to most people for mechanical damage to the body.

content: One note to throw in: if a device's owner is choosing to get it repaired then very much by definition they care about the device enough not to want to throw it away. Leaded solder being used to repair a device is very unlikely to end up as a landfill pollutant, because devices that get repaired are the ones that won't be tossed.From a practical purpose one should definitely always repair a device which already uses leaded solder by using leaded solder, mixing leaded and unleaded can lead to very unreliable joints. If the device started off unleaded you'd likely be best using unleaded, but if you cleaned off the unleaded solder from the joints being repaired then you might get ok joints still with using leaded solder as the amount of unleaded "contaminant" would be pretty low. You'd still probably want to work at unleaded temperatures throughout any mixed solder types scenario, just to be sure.

content: Thanks for sharing the article. I vaguely recall reading it when my job threw away heaps of soldering stations when transitioning to Pb Free.The article, however, is talking about 0,5% or 1,0% contamination instead of a complete cover of the lead/pad with Pb solder, which is what a repair person would do when replacing a single part. The Pb/Sn alloy will dominate the soldered connection and it wouldn't be subject to the adhesion effects mentioned in the article.Of course, this would show problems in reflow (rarely used for repairs) or for a future repairer if they try to fix the same joint with Pb-free solder. Worse, his soldering tip will be contaminated as well. So, don't use Pb/Sn solder and use a different tip/soldering iron if you can (not many might be able to do it due to $$$).

What I said is that it’sdifficult(not “impossible”) for consumers to buy because it’s illegal to sell it to them. All of the major continental European distributors (Distrelec, Conrad, Reichelt, etc) have stopped selling it to consumers. They’ll still sell it to businesses.2. I’m not claiming anecdotes as “evidence” of my position, I’m claiminglaw, and that law has been shown to you.3. RS doesn’t sell to consumers. Mouser is American (and I’m honestly not sure whether they will actually ship leaded solder to a consumer). Amazon.fr doesn’t sell leaded solder. (Some third-party sellers do.) So… you’re proving my point?4. A local seller is not a “reliable source” for what the law is!I’ve read multiple articles about how small shops are knowingly breaking the law by selling it to consumers.5. Switzerland isn’t in the EU, but a) that doesn’t mean I can’t be knowledgeable about EU law (just as livinginan EU country doesn’t guarantee knowledge of the laws, as you’ve plainly demonstrated), and b) Switzerland actually follows many EU regulations, because it’s easier to conduct trade. Switzerland does follow the European Chemicals Agency (ECHA), so the restrictions on selling lead solder to consumers actually do apply here, too.6. Nobody is copying “legends” from forum to forum, people are copyingthe letter of the lawto you.In a nutshell, it’s incredible that you just act like “I was able to buy some, therefore the law doesn’t exist”, despite being shown the law in question. You should learn to shut your mouth when people more knowledgeable than you say things to you.Quote from: mushroom on October 01, 2022, 09:42:30 pmRight. And if you’d read my original post carefully, you’d see that I didn’t say it’s impossible to get, just difficult. It IS forbidden (for consumers), but it doesn’t mean it’s absolutely impossible to get, and I never made that claim.

content: Just remember that many people don't read prior responses (the original post was asking about specific US repair places). Unless you're stating your context every time you reply, you're dealing with the readers local context of "the law", which simply isn't the same everywhere.This is one of those cases where people that choose not to have country codes displayed (or display something clearly not true) actively shoot themselves in the foot contextually, since even the reasonable assumption isn't available.

content: Quote from: tooki on October 02, 2022, 01:32:33 pmthis sounds like a very oppressive law, that allows something to be sold to one group of people, but not to another.if it is accepted that lead is hazardous substance (i am not commenting on this being true or false), then i could see that purchase could require that the purchaser has to hold alicenseof some sort. much as purchasing radioactive substances requires a license. likewise for firearms.but we arenottalking about a license. the present case seems more akin to one of saying "white people can purchase alcohol as they are responsible citizens", while "black people are not allowed to purchase alcohol as they behave badly after consuming it". such an argument is repugnant in any civilized society.in the case of lead, i could therefore see these 'laws' that apparently exist in Europe as anti-competitive, and furthermore an outright restriction of trade - something frowned upon to say the least. i'd not want to be a part of any society that so willingly tramples over its citizens freedoms.cheers,rob :-(

content: Quote from: robert.rozee on October 03, 2022, 03:10:57 pmFundamentally I agree. Same with the >15% sulfuric acid ban, >12% h2o2 ban, etc, especially since all those have legitimate household applications that cannot be done effectively by the more dilute versions.In most cases it's a non-issue though. Anyone can stop being a consumer at any point they choose by registering a business.

Oh, that's horrible, nobody should restrict trade of anyth- wait, no, everyone does that.Equating "this substance should only be used with care for good reasons" with racism does not make a very good argument.I imagine you're against restrictions on the sale of alcohol and tobacco to the underage, too.

I should point out you're talking about a country which spent years outlawing the export of ideas outside their borders, and actively seeks day in, day out to undermine the privacy and security of its own citizens. But it's all good because you can buy lead solder you don't need.

content: Quote from: KaneTW on October 03, 2022, 03:38:28 pmIt's getting worse all the time. About 10 years ago I had a heck of a time finding HCl for etching PCBs, now it's very difficult to find H2O2 stronger than 3%. More recently my state outlawed the sale of small cans of R134a which is obnoxious because I'm licensed as a refrigeration tech so I can buy a 30 lb jug of the stuff but I don't want to spend $400 on such a huge quantity that will take up storage space when the small cans meet my needs. I'm thankful that I can still buy lead solder at least but I'm sure that will get banned at some point too.

content: They mostly argue with terrorism/extremism/green deal fight - you can hide there anything from one hand knives (banned in Germany) to chemicals (mostly banned on EU level).HCl - that is currently available at least in our countryH2O2 - ban does not make sense, since you can buy black powder with age check and diperoxides are dangerous like a hell - whom they try to save? The few people experimenting with it? Criminals source professional stuff. It is mainly used for household applicationsH2SO4- I do not understand the ban.Pb ban - as mentioned before does not make sense for end consumer. I know the guy who suffered lead poisoning, but the reason was, that he was smelting bullets in closed room - it has nothing to do with electronics. It is issue for fishing, shotgun hunting etc. As far as I know the lead cannot be used with hot water (lead water pipes had been used in some old houses).Hg ban - it is liquid and if someone spill it on floor, than it is hard to remove (it is not an issue to use it in dentistry, where it touches directly the food) On the other hand it was quite hard to obtain before the ban.End consumers bans - law obeying citizens are not happy and criminals do not care about the bans thus getting advantages from it.

content: H2SO4 - sulfuric acidHNO3 - nitric acidso what do Europeans use as an electrolyte in their lead-acid car batteries - of whicheverycar (including hybrids and, i believe, most fully-electric cars) has one. at least in this part of the world, even fully-electric cars still include a lead-acid battery to power the radio, lights, and other low-voltage accessories.if H2SO4 is banned, then so must be lead-acid car batteries!i'm now starting to understand why the British were so keen to part company with the EU! it is sounding like a most horribly controlled society.cheers,rob :-)

content: There is an exemption for sulphuric acid inside batteries, and you are not allowed to pour the acid out of them(Last time I checked, I could even get a bottle of 40% at a battery store and they weren't aware of the ban or didn't care).The homeland of George Orwell was half the reason for all this idiocy, so I am glad too that they are gone. Now, if France and Germany could go next...

Nitric acid, nitromethane (rc car fuel) and lots of other "bomb chemicals" were outlawed even earlier.IIRC Breivik (Norwegian mass murderer) also sourced his bomb materials from...Poland

content: I think Poland understands the need for like interested chemists, easy industry, etc. It might actually stay a sizable industrial power rather then being pidgonholed into some esoteric market like some other EU nations. If you have a good chemical industry thats a high degree of autonomy that means that your kinda self sufficient. You have plenty of implemented experts (not people who have the knowledge and no way to use it, aka will leave at first sign of trouble). It's harder for other people to 'pull your strings.' Of course its all interconnected but it must mean something during international negotiations.But also I think its important to remember the gun killed 63 people, the bomb killed 8 and wasted his time and money. I guess it did injure alot though. Not saying which one is worse, but the gun is certainly easier. He had to make a cover story, front companies, business plan, etc (not to mention construction and transport), I think he had to develop quite a criminal mastermind scheme to implement that bomb plan. While with the gun its just 'hi, i like to shoot things, here is $500'. If he put that bomb money into training others, he could have done even more damage.For those interested in a (sad) song about the event, search forRöyksopp & Susanne Sundfør ► Running To The Sea (Studio Version)I don't think its appropriate to link the video in a discussion this serious directly because its still kind of a fun song, if you don't know why it was written.I imagine there is alot of opportunities in Poland for industrial chemists, since there is alot of heating plants (which themselves benefit from things like air pollution filter research, corrosion research) and there is bound to be a increase for self made advanced goods due to the Europe situation, with the amount of strife the Ukraine war put into the eastern European states. It seems like anything can happen there politically (maybe not in Poland, but the other post-soviet states)...

content: Nobody understand anything and certainly not politicians, it's only chaos that saves us. You see, the EU bans various things that nobody here cares about, but it doesn't send money to enforce the bans, so they remain poorly enforced. It's that simple.If there were special handouts for that, politicians would immediately jump on the opportunity to steal half of the money for themselves and the remaining half would then go towards knocking on the doors of the remaining vendors of leaded solder, battery electrolyte and so on. That's how it worked when we were friends with the USSR and that's how it works as friends of the EUSSR

content: those decisions should not be taken lightly because it all screws up jobs and that screws up the cities and towns, things should flow.But I agree that when you follow every regulation that people make then its like a joke, you start getting complaints about money/time/progress from people you would never know existed. Managers know which directives to ignore in order to maintain work flow, I think the economy is similar.All the problems that these kinds of regulations are often meant to prevent just have their underlying roots grow deeper when there is no money. People get money, people get their products and services and then people forget their problems and vendettas when they see there is so much they can do with life and their resources, its when they are stuck that you get problems (at least for the reasonable majority), which is why the *SSR/PP/C(om)P etc subfix countries always have high amounts of discontent in their population.Kinda always reminds me when you are in a bad place at night and you get all these thoughts and anger/fear but then you are thankful you have a couple of bucks in your pocket to call a taxi and then you forget about it for the next decade (wheras before you were ready to dedicate your life to protest or whatever)The only problem with poor enforcement is that sometimes it can be misused to target someone specifically, if they know everyone is doing something, then you can choose targets for whatever motive with very high 'hit probability'.... poor enforcement + stiff penalties = russia. if the penalties are weak/moderate, at least the effects are mitigated.

content: Quote from: james_s on October 03, 2022, 03:45:35 pmjames_s, you should be able to get HCl at any pool store in the shape of Muriatic Acid, which at 37% is already quite strong but can make a good etchant mix. H2O2will probably be worth to pay a visit to the Hair products store - you can usually get up to 30 volumes (40 if you have a license of sorts) in both cream and liquid forms. Also, with the covid craze, even Amazon was selling 7% (IIRC) gallon jugs.

content: Come to think of it, during the covid craze the pool chemicals based on Chlorine were indeed in very short supply - at least where I live.The substitutes that I saw are CO2or some variation of it to create carbonic acid, but the quantities needed are incredibly higher that muriatic.
