PCB board damaged, need help to repair or to find new one

[NunoMPG]

Hello,

My brother has a small helicopter, it's a 2 channel coaxial rotors. The problem is that he tried to build a new body for it in that blue foam but when he open it up he broke the little pcb inside... i'll attach some pictures of the PCB and you can see where and how it's damaged... is it possible to repair? if not, where can i find a new one (or used) to buy? is it worth to buy or is better to buy a new heli?
please help

Thank you

you can simply use wire jumper if there is no part damaged backside of pcb.

Can you help me do the wire jumpers? the attached image is the backside of the PCB... in the first images the damaged place you can see on top of the PCB is where the switch, the switch had to positions, the heli off position was also to charge the battery and the ohter switch position is to turn the heli on...

Can you help me?

Thank you very much

As the board is intact, only the mtalic track is damaged, the only solution to repair the track for current continuity and it would be completely workable.

Just scratch the green paint in both side metal track to open up the metallic part of each track. Then solder each track from one end to other end and connect with a bare copper wire or silvered copper wire. to make current continuity between both side. This is called wire jumpering.

And your PCB will be completely workable.

yeah do it as KALYANPRODHAN mentioned.light green colored tracks are metal tracks.check and study your circuit carefully.you can directly jumper wire between two components if you don't want to scratch tracks.if you don't know just contact your nearest electronic shop and ask them to do this jumper work.

Could this be a double layer pcb?

anyway, i've studying (as far as my knowledge in electronics goes  ) the PCB and i believe that the places pointed out by arrows on the attached image are the ones that were connected by the switch that got broken on the other side... can you tell me if this is correct? the switch was a regular on-off with 3 solder points, when i turn off the switch the heli could be put to charge and the other position was to fly.

Sorry for late reply.

1. The PCB is with double layer track (Up and down), but has no intermediate metal layer. So don't worry. Correcting both side track will be sufficient.

2. If the switch is disturbed, replace it. you will find similar switch to cellphone service technicians. But id the end terminal is the culprit as the current will not going, just make electrical path however you can. it will be completely workable if not you have removed any device while rubbing it (or cutting for which the marks appears and tracks gone off.)

Thanks
