Pad Type Differences Explained

what is the difference between smd, hold, std and conn in pad type
Here’s what the Flux documentation says about Pad Type options:
"Pad Type
Modifies the type of pad to one of the following:
  • SMD – a surface mount pad with no drill hole.
  • HOLE – a drill hole with no copper.
  • STD – a through-hole pad. (STD stands for "Standard".)
  • CONN – a connector pad with no drill hole, often used at the edges of a board."
