How To Repair A Burned Circuit Board
Circuit boards are ordinarily taken for granted until they fail to work. Circuit boards are important electronic elements in the functioning of any sort of device nowadays. Therefore, if you doubtable whatever issue with your excursion, you need to seek advice or replace one.
Always remember that there are 3 electronic agents of evil, these are heat, clay, and moisture. If these can exist avoided, your circuit boards volition stay live for a long time. One reason as to why circuit boards fail is normally because of burns which can exist caused by power component failure. When there is over or nether voltage on circuit boards, they can easily explode or burn. It can be easy to identify a burnt component, or one tin use a meter tester to identify if the circuit board is burnt.
Additionally, PCB (Printed Circuit Boards) components tin burn when loftier temperatures are experienced, peculiarly when at that place is very little space effectually them. Excursion boards have a item amount of heat that they can absorb, which is dependent on their structure and size.
Circuit boards too known as motherboards in computers tin can become overheated with fourth dimension, resulting in damaged components. With a specific set of repair skills and a few tools, repairing a circuit board tin can be done at habitation.
Footstep i
Examine the size of the area that is burnt and determine the extent of the burn down. You volition notice the range in color of the burnt portion from black to brown; this fabric should be removed each time it is identified.
Stride two
Cut away the burned selection using a screwdriver. You will run across beveled edges once the burn is cut from the circuit board.
Step three
Using a solvent, you tin clean the excursion board to clean off the excess particles. A combination of epoxy fluid and powdered fiberglass is then used to fill the area of the excursion lath that has been cut. The eliminated layers and the edge of the lath now become filled.
Step 4
Using a pocket-size tip of a soldering iron, smoothen the surface of the repaired circuit board. You can besides drill holes in the repaired expanse to place screws to agree the board in position. Always utilise a small drill bit because of the surface expanse nowadays.
There are cases where the board can take burnt traces. A specific case can be one in which a new fan placed on the motherboard causes the +12v line between the ATX and the fan to burn. The interesting part virtually this damage is that the computer will however work, just one cannot use the PCI slots and fifty-fifty the AGP slot while the issue still nowadays. The lath needs to be fixed in case y'all need to add together a video card.
The following tools and materials are needed in this procedure.
– A soldering iron
– A box cutter
– A wire
– A tape
Precaution
Unplug the reckoner'south ability cable from the wall socket.
Protect the parts on the motherboard during the whole practice.
Unplug all the chords from the board to avoid any accidents.
Repair procedure
Step i
Scratch the enamel coating from the motherboard trace. In case you want to solder from i solder pad to another, you lot can skip this step. If not, continue with the procedure.
Start from a trace's finish and follow it through to the other end. Spot the burnt spots of the trace and employ a box cutter to scratch the enamel blanket, until yous see a statuary/gold color. Repeat this process on each spot that is burnt.
Step 2
Using a soldering fe, solder the wire on both ends to the respective spots. Once this is done, the burnt spot will be bridged using a wire, which recreates the connexion.
Step 4
Tape the wires downwardly to keep it in position for a long time.
Footstep five
Plug the power back and turn the computer on. If blue fume is seen, you will need to bank check solder the correct positions again. Consider checking the soldered spots in instance you accept soldered the wrong spots.
