How do I make sure that through hole components, like screw terminals, end up oriented correctly? A lot of pluggable screw terminal bases appear at a glance similar. Moreover, there doesn’t appear to be a standard to indicate which way a screw terminal should point? I can indicate PIN 0 or PIN 1, but who says which end of a screw terminal has PIN 0 or PIN 1? The manufacturer data sheets don’t usually specify.
