The south bridge is a functional computer controller, also known as an I / O controller hub. Usually this is a microcircuit that connects "slow" interactions or bus connectors.
Necessary
- - electric stove;
- - frame;
- - motherboard;
- - solder.
Instructions
Step 1
Make an electric stove with your own hands to warm up the south bridge at home. To do this, use two bricks that have a spiral groove. They must be crimped with a steel casing half a millimeter thick, the legs should be about eighteen centimeters high.
Step 2
Make an open coil with a power of 2 kW. Do not install the regulator on the spiral. If, nevertheless, there is a regulator on the stove, experimentally select its position so that the temperature smoothly reaches one hundred and eighty degrees in one or two minutes.
Step 3
Cut a sheet of iron half a millimeter thick; its size must match the size of the slab so that it can cover the spiral while the south bridge is warming up. Take two frames from the system units, as well as a sheet of metal from them, where the motherboard is fixed. It is usually done with holes.
Step 4
Screw the motherboard onto the sheet from the system unit so that it does not accidentally lead. Then cover the excess holes with sheet metal. Desolder the output electrolytes from the motherboard. Place alcohol rosin from a syringe under the south bridge, place it above the stove at a distance of about fourteen centimeters. This distance will ensure uniform heating of the south bridge. Next, heat for about five minutes, until the flux boils.
Step 5
Put a sheet of white paper on the motherboard, then turn off the stove, add more flux after a few minutes to continue heating the south bridge. Turn it on again and heat at the same distance for about eight minutes, then lower it down to a distance of ten centimeters.
Step 6
After a few minutes, the solder under the bridge will melt, push the bridge in different directions with a needle, knock on top, turn it off and wait about forty minutes until it cools completely. If the bridge rises during warming up, place something like a coin on it.
