How to Repair a Burnt Spot on a Motherboard?

Motherboards are revealed circuit boards that contain resistors, transistors, capacitors, and different electric additives. Motherboards are temperature-regulated devices, blanketed through warmth sinks and fanatics. Sometimes over-modern can damage a connection and burn a niche at the motherboard.

Rather than throw the motherboard away in alternate for a brand new one, there’s a way to repair minor, and in a few cases, major burn spots. pcdiscover Any laptop proprietor can repair his motherboard with the aid of the use of a few unique products and tools, and following easy restore steps.

Step 1

Use a screwdriver to dispose of the computer or aspect case screws, and remove the panel. Place the pc case on a flat, easy workbench, with the motherboard facing up. Disconnect all of the peripheral gadgets by way of unsnapping the ribbon cables and wire pin connections. Use pencil and paper to attract a diagram of all ribbon and twine places, for easy re-installation

Step 2

Use a screwdriver to eliminate all of the screws that hold the motherboard to the computer chassis. Keep tune of all non-conductive rubber or plastic spacers and washers, and positioned them so as at the bench. Remove the pc case from the bench.

Examine the motherboard for brown or black discoloration. Check both sides of the board to see if the burn has penetrated thru. If one facet is burnt, use a pointy utility knife to scrape away all burnt cloth at the board surface.

Step three

Look to peer if a circuit trace has burned via on both give up of the broken area. Scrape the blistered cloth away, as much as the ends of both aspects of the circuit trace, so you can see easy, vibrant connection points. Use alcohol and a cotton swab to easy the location, together with the shiny ends of the circuit lines. Mix a small amount of circuit epoxy in a plastic cup, consistent with guidelines.

Step 4

Apply the circuit board epoxy over the broken location with a cotton swab, constructing up the floor so it’s far inspite of the top of the circuit board. Use the end of a small spatula to degree the epoxy fabric, growing an even surface. Do no longer unfold the epoxy over the cleaned circuit lines. Allow the epoxy to dry and therapy in keeping with guidelines.

Step 5

Use wire cutters to cut a small piece of skinny jumper wire long enough to bridge the space over the damaged location and connect the two ends of each circuit trace. Heat up a soldering gun and soften a drop of soldering wire onto each end of the circuit trace.

Hold the jumper cord with tweezers and area one end of the wire over one solder drop. Heat up the solder drop and vicinity one quit of the jumper into the solder, whilst you region the other stop of the wire over the pinnacle of the alternative (cool) drop of solder. Let the primary solder connection cool.

Step 6

Place the top of the soldering iron on the second solder drop, letting it melt. Push the jumper wire quit into the solder with the tweezers. Let the solder joint cool completely. Mix some other batch of circuit board epoxy, and use a cotton swab to cover the pinnacle of the jumper cord with numerous coats. Let the epoxy dry and cure.

Step 7

Place the motherboard back into the computer chassis and insert all of the mounting screws through hand. Remember to put the spacers and washers back in their authentic locations. Tighten all of the mounting screws with a screwdriver.

Following your diagram to reconnect the peripheral device ribbons and twine connectors. Install the pc cowl case over the chassis body and tighten the mounting screws with a screwdriver.
