rear connecting board
Etymology
'backplane' originates from modern English as a compound of 'back' + 'plane', coined in the mid-20th century specifically for electronics to mean a flat board at the back of a chassis used for interconnection.
'back' originates from Old English 'bæc' meaning 'back' and 'plane' ultimately traces to Latin 'planus' meaning 'flat' (via Old French/Latin influences); these elements combined in modern English to form the technical compound 'backplane'.
Initially a literal compound meaning 'rear flat surface', the term evolved in technical usage to mean 'a board that provides electrical and signal interconnections between modules'.
