I've a FXMC motherboard with a short on the DCBATOUT line.The moment the charger is plugged in to the board, it will block itself for protection. I have remove PR4402 for isolating the short, and making sure the short doesn't come from AD+_TO_SYS.

Hi Folks
I'm looking for a extreme high current short killer solution for a reasonable cost.
I have an LGA1700 motherboard (ASUS PRIME Z790-P WiFi) where I exchanged the LGA socket already 3 times, and every time after the socket exchange I get a short of power supply lines VCORE (V variable) and VCCIN_AUX (1.8V).

I check PPBUS_AON and there is a short present on the line, the computer shows a short when testing for short to ground, so when I inject voltage into the line, I get 0AMPS so no short is showing up. I have replaced a blown cap on this board that exploded and tested for the short and it is now removed. Any suggestions? I tested voltage at the line when the fuses are connected and I am getting 1.2 Volts at the line.

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...
