Ain’t it annoying when you rip off the solder pad/copper off the Naze32 flight controller (or any other PCB)? Fear not, you might be able to repair it!
I pulled the RC1 and Radio 5V solder pads off my brand new Naze32 board when I was removing the pre-soldered pins. As I primarily run PPM, and it’s currently not possible to do PPM apart from RC1 pin (as far as I know), it pretty much means I had to run PWM, or ditch the board and get a new one. (because I am using UART2 on RC3 and RC4 pins)
In fact the RC pins are all very important, they all have their own jobs, and not interchangeable at the moment:
- RC1 – PPM
- RC3/4 – UART2 (TX/RX)
- RC5 – LED
- RC5/6 – SoftSerial 1
- RC7/8 – SoftSerial 2
How to avoid pulling off PCB Solder Pads
Don’t apply too much heat on solder pads for too long, and don’t apply ANY force to them while soldering / de-soldering.
Fix Ripped off Copper Solder Pads
Luckily enough I was able to repair mine! Although I don’t know how reliable it is going to be, at least it seems to work for now.
- You can repair this by using a knife to scrape and expose the trace for that pin/solder pad
- put solder flux on the trace, and tin it. Clean and remove excessive flux
- finally solder a tiny piece of tinned tiny wire (30 awg or 28 awg) to connect the trace to a header pin or something. i didn’t even use a wire, I just push the header pin right in, as close to the trace as possible, and solder them together. (See RC1 pad, and 5V Pad)
