In this project I will show you how we can fix or repair a broken PCB . Sometimes when we are shifting our things from one place to another or just a circuit board fells from our hand then the circuit board breaks down and becomes idle . This is a common problem with us . And it also leads to new buy of a circuit board , a normal good range transceiver costs about 40 $ which is costlier than arduino but in this tutorial I will show you how we can fix it . Not only joining but also making it working.Here's a video of it working :-
Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.
Step 1: Nice Challenge
In this project I will show you the fixing of my transmitter that I broke down when opening my drawer it stuck and broke down Its power supply portion was different than its controller . But this idea helped me to reapir my broken transmitter.
Step 2: Things Required
For this fixing we need :-
- soldering iron
- copper wires
- broken circuit board with all constituents like capacitors,transistors etc. to make it working.
This is all we need to repair our broken circuit board.
Step 3: Identify
Firstly identify the correct wires by placing your two or more broken parts correctly like solving a jigsaw puzzle and then move to next step.
Step 4: Scratch
Scratch the corresponding metal flows in circuit board on both side (as the upper green coating on circuit board is insulator ,and the inner copper clad is conductor). Scratch a small portion over the corresponding side leave some space between two scratches as if solder connects two wrong wires then the PCB will not work. Use a blade for this scratching task .
Step 5: Stripping Wires and Placing Right Wires
Now take a long copper wire and with the help of stripper and a pair of pliers strip off the whole wire .Take a single wire and then place it on corresponding scratches over both broken parts . Don't make the wire contact with other soldered parts.
Step 6: Solder the Wires
Now carefully solder the wires from one side firstly and then solder the right wires on both sides respectively.Don't spell the excess solder on other scratches .
Step 7: Soldering on Other Side
Now start soldering the correct wires carefully on the other side . Again don't spell the solder on other scratches . Do it until all the joints had been joined.
Step 8: Final Soldering and Spreading
Finally all the wires are now joined . Now the thing is to spread the wires carving outside . Making curves so that they do not touch with each other to malfunction .And now your circuit board will work smoothly and It becomes more flexible now it will not break if thrown on ground!
Step 9: Working
Just Connect the battery to circuit board and then switch it on you will be surprised to see the circuit board working ! This project is economically beneficial to our community and makes it more flexible than earlier . This idea might be useful for all of us . But I think it had helped me to fix my 3 circuit boards , now working fine .Please vote if you like !
