    Default Need Tips on Repairing a DC Power Jack for a Laptop

    I haven't done much soldering/desoldering on circuit boards since my computer engineering days in college. I plan on using a 5W-40W Weller iron along with a desoldering wick to remove the old joint. So, here are my questions:

    - What size wick should I be using for something on this scale?
    - Where can I find a decent quality desoldering wick with flux?
    - What type of solder should I use (and where can I find some)?

    If what radioshack has available will do the job, I'll just grab what I need from there. Also, any helpful hints would be appreciated.

    Just ordered the following:
    Wick - http://www.frys.com/product/2530331
    Solder - http://www.frys.com/product/4455326

    Gonna practice removing stuff on an old circuit board and possibly an old graphics card with a 6 pin power connector before I do the DC power jack.

    Both items are fine for a standard repair job. Power jacks usually have a fair amount of solder holding them in place so keep cutting off the used up end of wick as it fills with solder. When desoldering the old jack don't worry about melting plastic in the jack, but do be careful to not damage the board (lifting a trace). When soldering in the new jack work quickly so as not to heat damage anything, but avoid a cold solder joint (solder should appear smooth and shinny when done).

    It'll help if you run a little of the new solder into the old joint first. This will lower the melting point and should make it easier to wick.

    I've read that. It is due to the flux in the new solder from what I understand. Supposed to clean the oxidation off of the old and encourage flow when pulling the new glob off.
