• Hey Guys,
  
  If i want to make a PCB that i can push into a connector (like a PCI card), does that have a specific name? Whats the name of the connector?
  
  Thanks!

• Awesome, thanks! 
  
  Any idea how you create the "golden fingers" in kicad? (its just a footprint  )
  
  I saw a few of these "edge connectors" on aliexpress and ebay. But all they mention is the pitch. To create your own you need a bit more i assume? Any idea if these are standard sizes ?

  Common edge card connectors are PCI/AGP/PCIe x1~x16/miniPCI/miniPCIe/m2, these due to being highly used in computer industry, are very cheap.
  Unless you have a lot of money that can justify designing another connector format, I would suggest using a PC standard edge connector for lowest R&D cost.
  

  
  I would go with this recommendation.  No use re-inventing the wheel (unless you need to factor in quantum gravity, superposition and chewing gum stuck under the table).
  
  You can then look up specifications to do your board layout - like this one for PCIe:

• Edge connector fingers should be plated with hard gold. This may involve an additional charge from the PCB fab as this is an extra step.
  ENIG is not thick or hard enough for edge connectors.

  Certainly not for a commercial product.  For a one-off hobby card, wouldn't it work?  Would the gold be damaged badly enough by a half dozen insertions/removal cycles for it to matter?

• Worked on a commercial project that is a plug in card in a garbage truck. They never use "Hard gold" even after 50 plugs the conctact is stil fine.

• For a one-off hobby card, even bare copper would work for a while.  The question is - how long is long enough?
