pads - These are the copper elements to which pins will be soldered. There
are two types:
Through-hole pads have a hole drilled through them so that the pin can be
passed through the hole before soldering. For a through-hole pad on a
multilayer board, there is usually a pad on each copper layer, connected
together by plating the hole with copper. This arrangement is called a
padstack. Through-hole pads are usually round or square. A common
arrangement is to use a square pad for pin 1 and round pads for the rest of
the pins.
Surface-mount pads do not have a hole, and are only on one layer.
Nevertheless, they are still represented by a padstack, although it is a
pretty simple one with only one pad. Surface-mount pads are almost always
rectangular.
