This is little tip for everyone, don’t buy Lead free soldering wire.
I know it sounds great idea, non toxic environment friendly and cheaper.
BUT!
It won’t melt, won’t stick, will crack, cold solder, and ruins ur components.
I bought cheepo solder wire says 63-37 (63tin/37pb), but it turns out to be lead free.
Honestly I don’t see the point. for us hand solderings it is completely useless
Now I see why some cell phone has dead board and cold solder.
I’ve been using lead-free solder for a long time and I haven’t really had that much of an issue with it. Sometimes it doesn’t stick super well, but then I just throw a little flux on it and it is usually fine. I feel better soldering for a few hours and not breathing little particles of lead, idk, just my opinion.
I’m so used to 60/40 that when I tried pb free, I burned my hands, and ruined couple wires. it doesn’t even tin the damn wire properly, with flux it worked better. yet it is not as good as 60/40.
I also heard, the long term issue with lead free. tin crystal grows and shorts circuit.
It will be depends on the quality of lead-free wires of course, but generally they suck! I rather turn the noisy fan with lead smoke.
So here’s the breakdown, at least in my experience and understanding. Technically it takes a lot of heat for lead to actually burn and produce any fumes, much more heat than a soldering iron can produce, however the fumes from all solder are bad for you and are known to cause asthma, and generally not cancer. Use whatever solder you have a preference with. If you use lead free or any high melt solder, buy some quick alloy to feed into those joints during removal and it will make life easier. Lead free or leaded are both bad to breathe in, so buy a fume extractor for $20 or set a fan up in a well ventilated area. 63-37 is probably the easiest to work with for most people, just because it melts easy and is either solid or liquid with almost no in between.
My father was an electrical and mechanical engineer. Spent his entire “short” 55 year life soldering and CAD work. He was diagnosed with lung cancer at 51 and after surgery, chemotherapy and radiology, he died from it spreading to liver and brain. Doctors thinks it stems from the contact andinhalation of lead in solder from the 70’s - 2000’s. From what I can remember he’s always done it at a window or garage with a fan sucking the fumes out. I’m hesitant about lead solder but they do have better results.
I’m sorry to hear that. It’s definitely possible, also solders back then had different chemicals in their flux core than modern ones, so maybe that caused it. Nonetheless, that is a terrible tragedy and I’m sure he was a great man. The last thing I want to say, since this is such a serious issue that’s easy to overlook is all of these chemicals can be found in solder fumes:
Chlorophenol
Formaldehyde
Glutaraldehyde
Benzene
Phenol
Ethanolamine
Hydrochloric acid
Acetaldehyde
Styrene
Toluene
Isopropanol
Acetone
Bottom line is, know what you’re doing and never solder without proper ventilation. If you have to wave the fumes out of your face, you’ve already breathed in the “threshold level” of chemicals for the day. Here’s an article from Weller for those interested
480 degrees C, granular tuning down to the fucking degree and its only $50. Not only that, the same store has the tips and the replacement wands all day long for just as cheap. Looks like they’re out of stock at the moment but that’s no biggie. They’ll be back very very soon. I shop there a lot.
OR you could walk into radio shack and pay $20 for a 15 watt iron (if you can get past all the fucking phones and back into the tiny corner where they still have an iron and maybe a drawer with some LEDs in it) and hate yourself, or go to the hobby shop and pay almost $40 for a 30 watt handheld that doesn’t even tell you how hot it is and doesn’t get as hot anyway.
Weller makes good stuff, my dad still has his irons from when i was a kid.
Also you have a 100W iron so the most important consideration has been considered. Heat. Some of these crap irons that are marked up are less than 30 watts which is barely usable for anything. I’ve seen 25 and even 15 watt irons on the shelf for $35 before. ITs retarded. People can get trapped like that.
Good luck but preach on brother. I have been telling people for years, “you need a bigger iron”. Those little pencil tips just don’t cut it on fat cables. So many bullet connector out there are barely hanging on, riddled with cold joints.
yes sir! i fix a lot of that shit in other people’s boards. people would be shocked how little solder it actually takes to make a very strong forever lasting weld in a bullet because they forget about flux and heat. The shit has to flow and bond.
you need a hot fucking iron and the 15845-TL series stations are solid at a rock bottom price for what it delivers.
I can see myself spending a shitload on a full hot air station one day but for now, i’ve got three of these things and i love them. And for $50 i mean damn. I seriously want a bad ass reflow station though.
I have three of those rebranded combo units. Two of them live in the bone yard/intern parts haven. I finally broke down and bought individual units. The cheapo hot air units need to be allowed to cool off before turning them off, if you turn the fan off before the element has cooled they tend to fail. Now that I follow that procedure I have not had one burn out on me.
that link is just the first one I found on eBay, I don’t know if that is a trusted seller or not.
but the soldering irons are amazing, 65 watt, with pid temp control, filed interface, g sensing.
they can be set to heat up when you shake them and turn off after inactivity. There are mod firmware.
they run from a wide range of power sources, I have a lead with clips so I can run it off the car battery, and a lead with connector for my lipol pack. You can also power them from a usb C power supply through a adapter board.
Anyway, guessing you have already all.come across them but if not, highly recommended
