The copper backing plate is placed above the groove on the circuit board and lowered such that the copper tracks enter into the grooves on the circuit board and are centered within the recessed circuitry of the circuit board.  The assembly is then cured by heat such that the epoxy becomes a solid and holds the copper tracks in place.  The assembly is put into an etching tank which will react only with the copper so that the total copper backing plate is removed, leaving only the copper tracks embedded in the grooves.     - i -
