Burned DC jack - worth a try?

[magneh]

Hello!

Got this Mobo from a friend, it has a burned trace near the DC jack.
it works, but when turned on , it smells burned normal.

It's the first one I get like this, does it worth to change the DC jack or how to treat this mess?

Thanks for your inputs!

Cheers

Well if I was in your spot, I would replace the jack and after lifting put some fresh solder mask on the burned spot.

a knock to the jack at some time may have fractured that board, that's why the arcing maybe

well just work the board like in a rock mine , with a dremmel start removing layer by layer but at same time you must leave a bit of visible layer , in case there is a hole on the board , just saved a ASUS board this weekeend like this , in the end the hole had 9mm wide , but board works fantastic

Eheheh ... nice job HighPulse!
Got any pictures of that job?

When you say removing layer by layer, you mean removing the burned part?

Thanks!

mather in fact i dont , since machine left for client , but imagine that a board have several layers , bottom top and 3 to 6 layer on the midle of baord , they all have very small distances between each outher , around 0.1mm to 0.25mm , what i did is , started removing the fiber part on the top ( in my case first i removed major part of VCC layer on top and botton for i can room to work the layers , after having a good range to work with , started removing with the dremel the fiber around the hole , removed until reach near 2mm of the top and bottom VCC , when i start seeing the inner layer above the top one , start consuming its cooper until there is not cooper to see frmo that layer , and removed a bit on the sides as well (because the smokes comes frmo layer touching on each outher generating shorts) so you must do things like the ROCK mines , let me chek a picture for you can get the point of my idea(well its a rudimentar pictures but yuo can get a idea how i solved my problem after each layer you work , with the multimeter , chek with continuity between ground and VCC , if you GOT value 1 , then it must be 100 without short , now attention , if it dont BEEP , but you have a value like for ex , 655 its not ok yet , you must clean well until you have certain all is good . when you got no longer short , i advise to insert in the hole a good non conductive epoxy glue and let it rest for 3 hours at least , then , chek if you have still places for the DC jack pins , if not , you must make some wire work and thats it
