Very good, very simple. thanks very much. /bklyn👑

As someone who washes his hands 400 times while cooking, this has given me lots more confidence.

There are no problems with modern lead-free solder, it just isn't as shiny. Weird hipster hobbyists and boomers insisting that putting lead in all our electronics is safe and fine is actively harmful to human health. You apparently haven't noticed that soldered electronics are EVERYWHERE. `

Why would silver brazing have been used 3000 times on the Thresher instead of welding?

many thanks, I was not figurin out how to open by pushing

Actually, having been in electronics now for 40 years, I used to get lead level blood tests and the doctor consulted his PDR and told me that "80% of inhaled lead fumes are absorbed" (not good)

It's soLdering, with a L

You are so wrong saying that the fumes do not contain lead. Well the fumes (the rosin fumes) do not. But lead still evaporates from the melted solder. Constant exposure (not like a hobbyist, but daily repair) could cause lead poisoning.

Source: trust me bro

I lay a newspaper on the table on which I work. After soldering I can just throw the entire sheet in the dustbin so that I have minimal lead exposure

I use nitrile gloves, because it provides both the reduced direct lead contact but also protects my soldering from my hand oils. I'm finding I can run lower flux content wires (1.1% or 2.2% max) and still get excellent results with less flux residue to deal with.

I can't find hot element for int 8900 or on your page any suggestions?

I was very pleased not to hear an american calling it sodder!

Thanks for the safety tips!

RoHS covers multiple harmful substances.

Your stove doesn't have molten lead in it, hopefully. Plus it definitely doesn't have asthma-causing pine rosin in. You don't need to buy either lead, or pine rosin, to do soldering. Good soldering irons can easily go to 230°, and even a lot hotter.

Didn't enjoy the video i'm afraid. The only time you mentioned BRAZING was in your introduction. Then you went on to never explain what it was or what tempratures are used for it or it's use case! In my opinion it's the most important of the 3 to explain as most people know the extremes of temperature (Soldering vs Welding) so brazing would been the more interesting subject to have touched on, especially as it was in the title. Shame.

Excellent video, I replaced heating element on aoyue 852+ but it’s still blowing cold air, I followed your instructions precisely.. what else could be wrong? Really struggling without hot air station

what is the difference between ultrasonic cleaner and electronic contact cleaner? can't we use electronic contact cleaners available on amazon for board cleaning of amplifiers?

Did you just make a whole video on how to clean a pcb on an ultrasonic cleaner and left out the final step of removing the cleaned pcb from the ultrasonic cleaner??? You’re joking right? Smh.

Just a friendly reminder that all of your personal anecdotes are totally valid scientific evidence and lead always shows up in blood tests years after exposure...

This is super clear, thanks

SoLder not SoDer !.

It took me a minute until I realized that the SRA demo guy is played by Jimmy Fallon, reprising his role from Almost Famous. :-) ruclips.net/video/ssDLTadxMTA/видео.html

Hey! You guys still sell supplies right?!

I'm looking for a cleaner that's eco friendly, looking to clean circuit boards out of old radios, not so much flux and solder, but dust and gunk (spilled soda??) Could I use a little dishwashing soap (i.e. Dawn?)

I bought the Aoyue 474++ desoldering system and love it, The soldering station will be next. And I'm glad SRA is only 10 minutes from me..

Without lead in the solder there is the problem of tin whiskers. Also aren't lead free alloys more brittle? Sure they are better for the environment but all metals are toxic to some extent. Some are a lot more toxic than others. All metals are harmful when in certain concentrations.

Thanks for the video, well explained and should cover anything one would want to know, especially the points about leaded solder

I can't understand how you acknowledge lead is toxic, present alternatives and finish by saying: it's your decision.

I started soldering with 60/40 solder at around age 12. For the first few years working with the telephone company almost all connections were solder joints, many years of soldering connections. In addition to personal copper pipe soldering. I have made thousands of solder joints using leaded solder. Tried lead free solder a couple of times and just don't want to deal with it, now maybe it was poor grade or maybe it's my technique, regardless it's not for me. It doesn't flow well, all joints look like cold solder joints which were considered a bad thing with leaded solder. I will soon be 69 and my health is excellent, mentally and physically fine. If you are doing occasional hobby soldering what's the big deal, you can't beat 60/40 rosin core solder for ease of use. As a side note there were 2 main soldering irons - American Beauty 150 watt with long cords, they were plugged in and powered on all day and night - 24/7 for at least 15 years with no issues except a new tip maybe once a year. They were there in use when I started work and still there when I retired 32 years later.

Thought homie was wearing a beanie

What about pc boards with electrolytic caps? Aren't they vented and could have issues with this process? I came here to specifically look for info about that.

Grego: I am a retired electronic engineer and manufacturer. Have worked with lead solder using irons, dip pots and wave machines. I started as a hobbyist in the 1960’s and used maybe 100’s of pounds of roll solder and three loads in my wave machine (Electrovert) of 200lbs per chaa add age. Before retiring my shop Forman and technician wanted to get tested for lead in his body. We both got tested! We both had very low levels… no different than non electronic employees. As a teenager working on my projects I did not use any form of fume extraction! It got smoky in my bedroom. My engineer father build many Heathkits the same way! So the moral is… don’t put the stuff in your mouth to hold it while your hands are busy, and wash your hands before you eat!

Than you for breaking it down I would love to watch more of your videos I a. A beginner if begin a tech for electronics specifically on tablets and computers

If the recommended ratio is 1 part cleaner for 9 parts water, then why put 10 parts water for 1 part cleaner ;-) ? As far as I understand it should be 1800ml of water and 200ml of cleaner, no ?

Im a total noob to soldering, do I have to use the digital offset value function? does this thing have to be calibrated or can you just slap on a tip choose a temp and fire away??

Read less, talk more.

I was going to buy some of the PCB cleaning solution but shipping was almost as much as the bottle itself. Nearly $50.00 for a 1 quart bottle of solution? I am new to this, does that sound right?

I chewed some solder some time ago and now I am scared Am I safe or what?

You forgot to mention that lead free solder is banned in use for aviation due to the fact that non lead solder is much weaker and prone to popping off the joints and cracking etc when lots of vibrations and heat cycles are present.

I'm working with musical equipment, mostly through hole, analog, hand soldered, nothing super tiny, and from my experience lead free doesn't really work in that environment, i can not imagine repairing/putting together a proper tube amp (for example) with lead free solder.

What is the name of the cleaning solution that YOU used? Geeze

Glad to see you are also wearing a safety helmet.

What about handling lead solder? As an electronics hobbyist I've easily gone thru 10 full spools of solder in the last 2 decades and all of it handling 60/40 with my fingers. Does lead build up and stay resident in the body?

Half the story. You just left the water on the circuit board, inside and beneath the components?

Leaded solder as an electrical connection and conductor tends to remain stable over a much wider range of temperature extremes, as well as vibration and mechanical stress, then lead free solder does. Leadfree solder is also far more likely to cause short circuits from the outgrowth of crystalline dendrites, also known as tin whiskers (Google the tin degradation phenomena known as "tin pest"). Alloying tin with lead ameliorates this problem. The breakdown of connections made with lead free soldier results in millions and millions of electronic devices failing prematurely every year and ending up in a landfill. If the ultimate goal is to reduce E waste going into a landfill then leaded solder is actually better for the environment. There are also many other toxic medals and compounds in electronics besides lead, and really they should all be recycled, and built to be more easily recyclable, regardless of what type of solder is used in their construction. This might make me sound cynical, but my estimation of ROHS (reduction of hazardous substance) trade agreements and legislation is that they were instituted not so much to prevent lead from getting into the environment, but to prevent manufacturers from being held financially and legally responsible to make sure that their products get recycled in a safe and ecologically sound manner. ROHS might be providing legal cover for companies to build millions of shortlived and disposable products that end up in the landfill. PS, I don't find rosin fumes from lead solder to be particularly bothersome ( your experience may differ), but fumes from the special leadfree solder fluxes are noxious and nasty and you definitely won't like them! Rosin flux is also mostly inert, non-corrosive and non-conductive, but leadfree fluxes *must* be completely removed from your circuit boards and connections, because it does conduct and is definitely corrosive.

What vintage keyboard are you working on at 2:10 ?

I just tried to duplicate your results, with SRA-brand, TT-21G Tip Tinning Paste, on a Sainsmart TS100 -type, digitally adjustable soldering pencil, that was properly calibrated. I found that a setting of 350C was way too hot, so that the waxy solid between the Tin particles, formed a defective residue on the tip. In the end, only a small region near the very point of the tip was tinned, the rest of my tip presumably phosphatized, so that I had no advantage over what I had before, which was, a tip-end silvered with the last-used solder, and the rest of the heating shaft clean. 😥 But, I was able to remove the dark-gray phosphate with a mere wire brush, meaning that only minor permanent damage happened to the tip-unit. 😀 After re-examining everything, I now conclude, that although the soldering pencil I named can be set to temperatures from 100C to 400C, it's not suitable for full use over that temperature range. And I think I've learned, that the TT-21G Tip-Tinning Paste is meant to be compatible, with high-temperature -type 'Silver-Sod' (which the pencil is not).

The real reason for the change to lead free is to make sure that consumer products satisfy the PLANNED OBSOLESCENCE ISO 666 MUST FAIL for next $SALE$ of new product. Follow the $MULA$... Very brittle and crystals grow to short out your circuits. If you buy new product, put 60/40 or 63/37 tin/lead solder all over board so that is doesn't fail within 2 days...
