Recapping Asus Board with Cool Stack

Re: Recapping Asus Board with Cool Stack

The very first solder iron I ever used was heated by sticking it in the fire in the stove.
[A coal burning stove no less.]
It was my grand father's.

Re: Recapping Asus Board with Cool Stack

No, I'm not using chipquick. Your problem is your flux is weak. I use plumbing flux with my 25 or 35 watt irons and I have no problems. I can even desolder large coils from multi-layered boards. The 35-watt I found in the trash. If this hobby makes me a million dollars someday, I might consider investing in one of those overpriced irons, but until then, I refuse to pay.

I don't have the courage to try zinc chloride acid flux on circuit boards, and while I've seen rosin flux help make copper desoldering braid work better, it otherwise hasn't improved my luck with circuit boards. I do remember needing more than 25W to remove a 1.5-2.0" cube transformer form a single-layer board, and I don't think the problem was poor conduction between the tip and solder. I've never paid more than $5 for an iron, not even for my adjustable 10-60W, except for an $11 Radio Shack desoldering iron.

How well did it work on surface mount chips?

How about for branding cattle?

Zinc Chloride flux is quite nice to work with, but it needs a bit higher temperatures to function properly and it is also quite wet and spews everywhere.
It removes oxides nicely, tho it doesn't improve wettability much. Ordinary flux is much better for this purpose.
It however does _magic_ on old copper wires (and is corrosive as hell if you hadn't cleaned it properly)

Fumes of such flux are also quite aggressive on your lungs and with no ventilation I would not recommend it.

Plumbing flux is something I would avoid as they are mostly acid based.

I dip my braid in colophony and 'tin' it a bit, works much better then, despite being a bit contraproductive, but you can't heat the pad with dry braid, does not work.

I dunno. I was about 10 or 11.
Worked pretty good for soldering tin cans together.

Re: Recapping Asus Board with Cool Stack

Just recapped a Asus P5AD2-E Premium with no success. Board LED lights, fans come up, but no beep, no post, no monitor. Wondering if the process of resoldering Stack Cool could have anything to do with it? When I replaced the caps, I soldered the caps to the Stack Cool, assuming/hoping the solder somehow drops onto the contact on the primary motherboard. Is that how it works? Does the Stack Cool have any electrical contact with the primary motherboard?

Re: Recapping Asus Board with Cool Stack

a 25w iron will only do the job if it has enough thermal mass.
25w radio shack cheapie?
fugettaboutit!
