Looks like you are going to have some fun with the mobo power connectors, makes for a neater system ;).

sweet :up:
I'm out of desoldering braid, so I'll have to run out and get some more in a bit here.
I've made the necessary cuts to the motherboard tray.
Perhaps some of you will remember this illustration:
The cuts correspond with this plan.
I love my Weller WES51 iron, It's a great unit but it's not getting hot enough. In fact none of my irons are working for me... even the massively overpowered 260WATT Weller D550, and the 40WATT Weller SP40LK.
Do motherboards use some kind of super high temp solder or something?
None of my irons get hot enough to make it properly workable, it just refuses to melt like one would expect it to.
Pumps, and braid have very little effect.
I've removed about %90 of the solder material from each joint but that last %10 wont budge, it wont even melt.
Any advice before I break out my little torch?
and I'm not buying a $600 hot air desoldering station - yet.
This is the first time I've ever had this much trouble desoldering - figures this happens to me on the first thing that I'd genuinely prefer not to destroy. haha
Factory solder really is tough. Unless you can get yourself an ultra powered soldering iron lol you would have to make do with your Weller.
I have several irons, and one is a massive over powered 260WATT gun - even when cranked to above 900deg nothing happens.
I tried my small 40watt iron (SP40LK), my weller station (WES51), my 260WATT gun (D550), and my SMT station (WD2000M)... none had any effect (and yes I do have a boner for weller products).
I've even tried using my solder to heat the factory solder... no dice.

Methinks I'll have to use a torch, but first I'm going to see if any of my contacts have any heat flow gear I could borrow.
I seem to recall a buddy of mine having a full blown turbine desoldering station.
I assumed it was wave soldered but I didn't think that they used kryptonite to do it.
I just plugged in my clothes iron and my IR thermometer says it's considerably colder than any of my soldering irons... so there goes that idea.
I think the only way I'm going to get this thing off is to use a soldering torch or a concentrated flow from my heatgun. I'm pretty sure both of these methods are quite likely to destroy the board though. If that's the case then when I get a replacement mobo I'll leave the connectors in place and just solder the wires to the bottom of the pins.
I'm going to wait and see if anyone has any suggestions for me, I've posted this dilemma on about a 12 forums... I guess this will have to wait until tomorrow to see what my fellow geeks have to say.
Pain in the ass.
um... ive soldered things offa my motherboards fine... and thats with a crappy "the Source" - Radio Shack $15 iron... 30 watt
So have I.. but this one is stubborn.
From the responses I've gotten on other forums, this seems to be a fairly common issue for wave soldered products.
With the new Rohs compliant products this is an issue. The leadless solder takes more heat to melt. and it's hard to get the heat into the vias in these seven layer boards. Might try a soldering iron that is labeled for leadless solder.
Good luck!
Great work so far!
That's exactly what I've been saying... so today I went out and got a new torch/butane iron.
I'm pretty sure I'll cook my board.
If I have to do it again, I'll leave the plugs in place - that would have saved me all this grief.
