Fix Ripped off Solder Pads on Naze32

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.

  1. You can repair this by using a knife to scrape and expose the trace for that pin/solder pad
  2. put solder flux on the trace, and tin it. Clean and remove excessive flux
  3. 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)

    I have prob destroyed 5 micro minimosd trying to solder the pins on. Very poor design. At least sell the damn things with the pins attached.

    Hi Oscar
    I had the video out pin solder pad pull off of a micro minim OSD module when I tried to solder a connector pin to it
    You can purchase some conductive glue to repair the pad as long as you can identify where the trace made contact with the
    pad. Two ounces for $1.50 on E-bay.

      Hi Tom,

      We’re you able to figure out where the pad made contact to the video out pin? That exact pad came off my micro minim osd as well :/
