Whats funny is your talking to these guys like they are nasa techs. They are weekend warriors and would probably only solder anything once or twice a year so they would probably not spend the money for a soldering station, even a cheap one.
My point was that a rat shack iron is more then fine for the work these guys are going to do. I use them every day and I'm sure my qualifications speak for them selves. Soldering stations do not make anyone a master solderer. But you can be a master solderer even with cheap rat shack irons......  |
yeah, they let me solder on the challenger parts and look what happened  .

Your only as good as your tools. You want to solder on a tv that's class I soldering with a shack iron, fine, but these projectors are built much better than that, to mil-spec standards. If you want to degrade the build quality of your machine, have had it. The methods I speak of is what the manufacturer would do, and that's what I want in my pj. That's how they last as long as they do. Others are free to do what they please. Just offering up advice that's more true to form of class III soldering quality.

Damn, so all these projectors that I've been soldering on for the last 17 years are going to start failing soon. Oh no..... 
Only as good as your tools......... Then I must really know nothing, I've been fooling myself all along...

Like I said, didn't mean to cause offense. Soldering is what I do, what u suggested is not class III. U can accept it or don't.

No offense taken here... I'm sure all the class III solderers here will heed your advice....

They won't be class III if they listen to you

I love how long this thread has gotten in the last day. After reading what I wrote, I wanted to clarify that if you buy a cheap iron and the tip isnt sharp, sure, why not sharpen it with a file. The tips are only $2 bucks, and the radioshack ones i have last maybe 2-3 times and lose their sharpness. For the boards in a crt, that isn't a problem, but for small devices like a cell phone, it just won't be enough. But cetainly, I would never recommend this on anything more expensive.
Just get the radioshack 30watt iron, and the blue suction device, and you'll be fine. And you won't feel bad about the money spent when you never use the iron again.

Sparky, you say there you solder at 650 C, do you really mean C or did you mean F? My stations dont go that high.

Haha, sorry, F. My testing is generally in C at work, but soldering I think in terms of F. Sometimes I get Celsius on the brain.

Careful, this is NASA sounding for some of this crowd apparently
Decent machine for the price, for sure.

I have no experience with Tenma, but for the price, sounds like a nice machine for a weekend warrior. Gives you the variable temp and a nice temp range that should suite the needs of what we are working on. I"m betting they carry a variety of tips to suit the application as well. You will be surprised how easy the skill comes when you actually have plating on the tip to get the solder to flow correctly.
If the tip is wearing out after 2-3 uses, your using it as a pry bar. A tip should last a lifetime for someone only using it a few times a week. We can get tips to last 6 months to a year at work, and thats 24-6 use using high melting point solders.
*Dont abuse your tips or use them as a pry bar, or file the plating off of them
*Keep the temperature as low as possible to increase tip life and reduce damage to what your soldering
*Use the right tip and temperature for the job
*keep the tip clean
*keep solder on the tip when not in use and turn down or turn off the iron when not in use
You do those things and you will be well on your way to being a "master solderer".

Not too space agency like.
However; I was think of staying under $150. I like the idea of a station with desoldering abilities. It is the de-soldering that concerns me more than the soldering. I have in the past melted some stuff. I was very young and using it as a "firestarter".
Something between these two would be great and I hope you can help me out.
Mind you I have zero experience here so I would guess a starter set-up list is needed.
Like
1 Desoldering/soldering station
2 various tips [Spell this part out]
3 Large Magnifying glass on swivel?
Anything else?

Now here's a perfect example. How many weekenders here would even be willing to spend this much on soldering irons. Anyone that does more then occasional soldering already know what they need. They wont be asking. But for occasional solderers who may not have lots of money to just blow can solder just as well with a cheap iron. You dont like the filing thing, thats fine, to each his own but a cheap iron can still do the job, plain and simple.

You may be hard pressed to find a rework station with desoldering capabilities for that price point. The cheapest I've seen with a quick search was $250, and that unit the soldering iron is more of a gun type, which I am not a fan of.
http://www.mcmelectronics.com/product/72-6340&scode=GS111&CAWELAID=220584301?gclid=CID3nNCVka0CFQmd7QodVnOInA
Here is what I use. Now, keep in mind this doesnt fit your price point, or most quite frankly, but I am using it for demonstrative purposes so you can see what I use, and the tips available for the soldering iron. That way you can do a search yourself and be a bit more educated of what your looking for in the price range your comfortable with.
http://www.techni-tool.com/static-products/pace/PaceMBT250SDDigitalHighPerformanceSensaTempSoldering.html
So as you can see, the soldering iron is a pencil, with the power supply as a seperate unit. Lighter, and allows you to get into tight places. So now on to the tips.
So here is a link to a set of 4 tips for $4. This type of size variety should be more than enough to cover the range. I also use a bent tip to help me get into tight places without burning nearby components.
http://www.google.com/products/catalog?q=soldering+tips&rls=com.microsoft:en-us&oe=UTF-8&startIndex=&startPage=1&um=1&ie=UTF-8&tbm=shop&cid=15339415021242457340&sa=X&ei=TcfwTuqaHcTYgQegz-mgCA&ved=0CIkBEPMCMAU#
Try to select a station that offers a decent tip selection. Buy this and take care of them and you shouldnt need to buy anymore.
Other things to get you started:
*Magnifying light on a swivel is great to have if you can afford it. I have yet to see these for under $200, so for home I use florescent light and a seperate magnifying glass for inspection of my work.
*Get yourself an ESD mat and wrist strap. Some components are resilent to Electrostatic Discharge (the whole rubbing your foot on the carpet and touching the door knob thing), others are very senstitive, such as ICs. Sometimes you zap them and weaken them, and they end up failing prematurely.
*To avoid using your iron as a pry bar, get yourself some nice tweezers and ESD safe alignment tool such as this:
https://webvia.techni-tool.com/VIA/viaImagePageIndex.jsp?row=0&pgName=viaListProducts.jsp&searchText=388sc5007&modifier=SEARCH&reqTitle=TITLE_VIASEARCHRESULT&newWindow=Y
This should get you on your way. I will see if I can't find a better desoldering station, but that may be tough to find at $150.
Again, this list is for those that like to tinker with their projectors and want to improve their skill, not the person using it once a year, so keep that in mind before throwing pot shots at me.

Oh, and by the way, I don't think I've changed my tips in my 2 irons in around 3 years and you can just imagine how much I use mine.
