Hey, i broke the usb connector on my limesdr, the solder pads got off the board, can anyone give me hints if this can be salvageable and where do i need to scrape to get the conductors back?
Print out the board layout & bring it to a professional shop.
I have been soldering since the 70s & I almost ruined mine trying.

Board layout? for what? they wont print another pcb and transfer all the components, i guess. I mean, that would take a lot of time and surely be really costly.
It wouldn’t take much effort to bodge something together with hot glue to hold the wires together 
though my skills with SMD are nil to none
I had a cord soldered on. Printing the board layout will help them determine the best places to solder. If you use just a touch too much heat, the copper traces will delaminate. Trust me on this. At the time, I was Foreman of electrics at an automation shop with 3 other very good solderers.
We all failed. Brought it to our board shop in the morning & had it back at lunchtime. Lady that did it said it was a breeze for her. Then she smiled and said she had only been doing it for 23 years as a job.
My USB3 wires ended up getting soldered right at the FX3 chip. Look at it & see if you really think you can do that. The other traces were just too thin to solder to.
