Question about pad

[keero]

Pad came off pretty much sums it up was tugging at wire to see if it was on good, must of use to much pressure. Trace seems to still be there. Ah well any ideas or pretty much sol :confused:

Ideally you need to get to someone with advanced soldering skills.

But you want to carry on yourself, you need a fibreglass 'pen' which you can use to scratch the laquer (green suff) off of the track revelaing the copper underneath.

If you can't get a fibreglass pen, then you can use something sharp to carefully scrap it away.. But be careful..

Once you have expose enough copper, solder the wire to this.. But be VERY careful.


However.. your picture is hard to see, so its impossible to know.. If this pad is a 'riser' (which connects to another layer in the board), then you are stuffed.. But I am pretty sure that this is not the case.

Good luck

Thanks for the response and sorry for the blurry pic, here's a better close up. I do have the copper exposed that leads to that pad. The pad is on that tape. Wii does boot up successfully and menu is fully functional, but when I try to insert a disc it hangs out halfway like rejecting it then spits it out. Don't know if chip will even remedy that problem not my concern now after that mishap, any ideas and thanks. How to tell if it's a riser? Hope it's not a multilayer :confused:

Pulling that pad off almost certainly won't be causing the problem you described. But the board IS Multilayer.. I can almost guarantee that!!

It doesn't appear to be connected to another layer.. Those normally look like 'holes' on the board. Although thinking about it, perhaps the pads DO connect to other layers? I have working in the electronics industry all my life and its just dawned on me that I don't actually know that those pads are for (The ones with a little blob of solder on them)

Normally, you see these types of pads in a place where a component COULD go.. But looking at the Wii board, there are losts of these solder covered pads and I am wondering if they do connect 2 layers together.

If this is the case then you are stuffed.. There is no way to repair that!!

I figured the problem out I had overtighten screws on the drive part and prevented the disc from entering. Other than that lifting the pad off that point didn't seem to do any harm, Wii is still fully functional. Thanks for the help.

Great news.. Assuming that you are still going to install the chip, what I would do is trim back that bit of raise track until you get to the point where its stuck to the board.

Then I would carefully remove the laquer and solder onto it there, securing the wire with some hot glue.. This will be fairly easy to do, as because the surrounding tracks are still covered in laquer, there will be little risk of short circuit.

Another option is to trace the track back to the chip and solder directly onto the leg.. BUT.. Unless your soldering skills are top knotch, I would avoid this, as it would be too easy to join a bunch of pins togther, or worse, apply too much heat to the chip and damage it.

Good luck!
