Talk:Q-plate

a-plate? c-plate?
I see these terms everywhere but can't actually find a definition or diagram of what they mean. Ultimately I've figured it out based on context and having seen the term in so many industries. It's ironic that q-plate has a wikipedia page before a- and c-plate, since it's based on these older terms. 162.246.139.210 (talk) 17:23, 13 December 2023 (UTC)
