"gore"

I work at an electronics contract manufacturimg facility. We do work for
several companies and I wonder why they use different labels on the
schematics and pcb's to refer to IC's. Some of them have a U1, an A1, and
X1, or an IC1. Why do they do this? Is there a standard used to label IC's
in a schematic? Just curious why this is.


** Like many things in the wide world of electronics, there are common
conventions that apply but no universal standard exists.

So folk in different places and in various companies do what seems logical
to them.
