PCB Manufacturing steps Are

• 1)PCB CAM
• The Gerber or Excellon files in the
  fabrication data are never used directly on the
  manufacturing equipment. But always read into the
  CAM (Computer Aided Manufacturing) software.
• 2)Panelization
• This is the procedure where the number of
  PCB's are grouped for manufacturing onto a larger
  board,this is called by the name panel.

• 3)Copper patterning
• To replicate the pattern in the
  fabricator's CAM system on a protective mask on
  the copper foil PCB layers this is the first step
  here.Subsequent etching removes the unwanted
  copper.
• 4)Subtractive,additive and semi-additive
  processes
• Here subtractive methods remove copper from an
  entirely copper coated board to leave only the
  desired copper pattern.

• 5)Chemical etching
• It is done with ammonium persulfate or ferric
  chloride.inner layer automated optical
  inspection(AOI).Afterwards mistakes can not be
  corrected,the inner layers are given for the
  complete machine inspection.
• 6)Lamination
• We have a trace layers inside the board that is
  Multi-layer printed circuit boards.

• 7)Drilling
• Holes through a PCB are drilled with
  small-diameter drill bits that is made of solid
  coated tungsten carbide.
• 8)Plating and coating
• In this step after PCB's are etched and then
  rinced with water,the solder mask is applied.And
  then any exposed copper is coated with the
  solder, nickel/gold, or some other anti-corrosion
  coating.
