360 controller pcb, what to solder to?

Still working on my custom stick. I’ve been looking at my early version 360 wired controller pcb-

Am I supposed to scrape away the black covering at the appropriate directional and button signal recievers (circled in blue) , then solder directly to the exposed metal? Just wanted some clarification on this…

Yeah, you got it.

Be careful scraping that carbon away, though. The gold traces underneath it are really thin and delicate.

Just take your time and you should be fine.

Thanks for the help.
