Great
(although i would have gone with a thinner wire)

Re: repairing traces...on a fine pitch board?
It sticks!
That's a 30AWG underneath that blob, and a 10¢ piece under the board.
Fortunately the tracks were relatively far apart, and only one track.Attached FilesLeave a comment:

Re: repairing traces...on a fine pitch board?
Triumphant(for now!) Used 30AWG wire and cheap crap orange flux that I had lying around...
DDR2-5333 DIMM module seems to work once more at least at DDR2-3200 speeds...
Now whether or not I dab some CA or epoxy over it to protect it...Last edited by eccerr0r; 04-14-2021, 06:29 PM.Leave a comment:

Re: repairing traces...on a fine pitch board?
i just strip some stranded copper wire for such work
usually from an old pc psu!

Re: repairing traces...on a fine pitch board?
Well, I guess the BGA doesn't matter, the break is nowhere near the BGA...
Need to think of a better source of wire that's not coated with varnish...or oxidation for that matter.Leave a comment:

Re: repairing traces...on a fine pitch board?
You may find some thin wire to use in some like phone earpiece, vibramotor.
As for visual,you may try some camera on phone or tablets with some attached lens.Need to experiment a little.Leave a comment:

Re: repairing traces...on a fine pitch board?
rossman has fixed that a few times on video - he uses very fine wire and puts a loop on the end to hold the bga ballLeave a comment:

Re: repairing traces...on a fine pitch board?
Unfortunately the ends are pads under BGA components...Leave a comment:

Re: repairing traces...on a fine pitch board?
Consider another approach:
don´t fix the trace... just wire end to end.Leave a comment:

Re: repairing traces...on a fine pitch board?
Scalpel blade... no check
$1 CCC Xacto knife... check
0.1mm jumper wire... no check
30 AWG wire... check
Stereo microscope... no check
1.4x magnifier light... check
All ready to fail! *sigh*Last edited by eccerr0r; 04-12-2021, 01:13 AM.Leave a comment:

I use a scalpel blade, 0.1mm jumper wire and a stereo microscope.Leave a comment:

repairing traces...on a fine pitch board?
Well I need to repair a trace... ... on a DIMM.
These tracks are tiny! What, hair line traces?
Fortunately the track is fairly long, maybe 1cm, and fortunately 1mm away from the next trace. Now I need to remove the soldermask. However this trace must be thin from top to substrate as well, how could I guarantee mechanical scraping wont abrade the track? What would one use to scrape off the soldermask for these hairline traces?
I guess the next thing after removing the solder mask is that the track needs to be jumpered. 30AWG Kynar wire is huge compared to this track...

When I assembled dreamcast I mistakenly fastened long bolt and It resulted in
cutting tiny trace.
This tiny trace(Total width of white coating is 5.5mm) is between R337,R343 and IC101 and it is covered with white coating in the below screenshot.
Firstly I tried to bridging tiny broken trace with my own eyes...But it is totally impossible..So a week ago, I ordered G1200 Digital Microscope and I magnified this tiny broken trace with it.
But It seems that It is really very tiny trace So I plan to order 0.1mm coper wire from aliexpress in order to bridging... -
KDL-60EX500. Comes on fine, sound is fine, backlights come on. Blank screen. Already tried reset POWER/VOL-. Anyone else have this problem? Possibly bad T-Con RUNTK4244ZZ or panel? Could main or power supply cause this? There were 2 blown 560u 35v on power going to backlights but they were still working fine. Thanks for your help. -
Got a case of something new weird at work. There is an old 2nd gen Intel i3 in an old “Pizza box” shell that has a small form factor power supply. Unfortunately I forgot to take pictures and model number off it.
Anyway, I get to work and get to look at this computer. Standby LED on the PSU is on, but the computer won't start. Hmm o.k. take the battery out of the main board try again, nothing.
O.k. then… unplug the power supply from the main board and put in a full size ATX PSU (yeeeesss! Exact that blown Powerman IP that I fixed a while back), plug it in and the old...

Hello guys. I have a problem with a PNY XLR8 GAMING RTX3090 graphics card. The problem is that it displays and works fine, but the fans don't spin at all. The problem occurred when someone else removed the fans in order to clean it and broke one of the fan connectors. He replaced it himself and after that, it wasn't working anymore. I guess he damaged something else in the process. What i have done so far: I found 2 capacitors next to the connector that were in a bad shape, he must have touched them with his tools - they weren't shorted, but i replaced them with similar ones from a similar card....04-12-2024, 06:54 AM -
Hello,
I know some might say... just buy another one. Sell it as parts..!
So had this AMP for quite some time. Recently I saw light smoke coming out of the AMP. Had my fire extinguisher close by. Just kidding. Turned immediately all devices off from mains.
Let things cool a bit, and opened up the amp device. I clearly saw on the main board which hosts the 5X amp (5.1), 3 10 ohms 1W resistors had their leads looking black, while the rest of the remaining 2 x 10 ohms were brownish as being installed from factory.
Spent some time downloading the Service...06-11-2024, 08:38 AM
