Use of long pads on prototyping PCBs

[petert]

Hi,

I have seen long pads at the borders of cheap PCBs you can get from amazon or ebay, but don't quite get what they are used for.

See here for example:



I would think they could be plugged into some kind of socket, like PCI/ISA/etc. cards, but I never found a matching socket/receptable, and they are rounded, unlike usual pads for such sockets.

What would be a "standard" use for them? And what are typical receptors/connectors for them?

I think they are used for wires or headers. Not sure there is a specific purpose other than providing some alternate way of soldering something to it.

I've used them to solder flat male headers to them. You can get angled headers through-hole but then the board can be in the way.
