Re: Hakko 808 Nozzles
I thought of that, so on my first motherboard I tried to desolder with this thing I sat there, waiting for the solder to melt for about a minute (I think the heat control was around 3). So I cranked it all the way up, and there was no change. That's how I came to the (potentially incorrect) conclusion that the nozzle may be to large and not making proper contact. I always wait the 5 minutes for it to warm up.
Somewhat unrelated question: You are also supposed to tin it with solder when not in use (so the metal doesn't oxidize, I assume?)....

Re: Hakko 808 Nozzles
I don't know where I'm having trouble. :P I have been doing that same thing. Sometimes it works, and sometimes it doesn't. Often there will still be a bit of solder inside the hole holding the cap firmly in place, even when I resolder and suck again. The outer diameter is 2.5mm and the inner is 1.0mm, but isn't it the outer ring that makes contact? Does the inner part make contact with the actual lead of the capacitor? I thought buying a $180 tool would make this easy, but it still takes forever to get a cap off, and I have already burned...Leave a comment:

Re: Hakko 808 Nozzles
I was working on a motherboard from a Dell Optiplex GX270 the other day, and it was giving me a fit because the pads are actually smaller than the nozzle size, so it wasn't making contact unless I came at it from an angle. What do you reckon the size difference is?
smason:
I've been having trouble using it on motherboards (I think because the pads just happen to be too small for the nozzle that it comes with; it gets up to about a bazillion degrees), but on PSU boards and stuff like that, it works like a charm....Leave a comment:

Hakko 808 Nozzles
I broke down and bought a Hakko 808 for desoldering caps from motherboards etc. I've found that for most of my projects the nozzle opening is too large and often doesn't even come in contact with the solder. The one it comes with is A1005. Which smaller nozzle should I get for use on a typical motherboard? I have no idea how large the heat pads (or whatever you call them. lol) are on these boards.
Here is a list of compatible nozzles on the Hakko US website:

Personally I don't see the purpose of mechanical keyboards. I prefer keyboards with keys that are easier to press. Feel free to attack me. LOLLeave a comment:

Re: Dell E171FPb Monitor Flickers
So the monitor will no longer actually show any picture..... I'm just going to call it BER and be done with it. I still don't know what's wrong with it.

Re: How Important are Low ESR Capacitors
Okay, thanks a lot.
so it's a pretty safe assumption That if ESR isn't listed, then it's not a low ESR capacitor.

The smart people who change Wikipedia typically aren't the ones that read it to gain knowledge.
What is impedance ratio? Anyone?...Leave a comment:

Re: How Important are Low ESR Capacitors
What is "impedance ratio"? I keep seeing it on datasheets but it gives me no real info on what the ESR is? How do I know what the ESR is from "impedance ratio"?

Re: Dell E171FPb Monitor Flickers
I don't have an ESR meter to measure it.
Which caps are you talking about?

Re: Where to put the white wire?
You are right; this is a cheap bastard. Going to just throw it in the trash and get a new one since I don't want to short anything out by continuing to use this. lol Thanks guys!Leave a comment:

Re: How Important are Low ESR Capacitors
Thanks! I read that Wiki article before and didn't understand a lick of it. But you pretty well answered my questions in a simple paragraph. Wkipedia needs more of the "human element", I think. Will go back and see if I get it now.Leave a comment:

What are switching power supplies? When are they used and why?

Re: Where to put the white wire?
It doesn't reach that far. Also, isn't soldering it directly to the hot wire creating a short?Leave a comment:

Where to put the white wire?
So my power strip with switches for each outlet just randomly shut off for no apparent reason, so I opened it up and found this:
The neutral wire came loose! I'm not really an expert on circuits (I just replace capacitors because it's obvious), so where should I solder the white wire back on???... -
Desoldering Tools Suck
I hate my desoldering tools. My flimsy plastic solder pump broke, and my desoldering bulb is clogged with gunk and I can't get it unstuck.
The last thing remaining is desoldering wick, which is RadioShack brand, and it will barely absorb any solder! Is it the brand I'm using or is it usually this difficult? -
Re: Dell E171FPb Monitor Flickers
The yellow stuff on the one capacitor on the power supply isn't leaking; it's just glue. lol...Leave a comment:
