Introduction

• A PCB is printed circuit
  board, also known as a printed wiring board. It
  is used in electronics to build electronic
  devices. A PCB serves 2 purposes in the
  construction of an electronic device. It is a
  place to mount the components it provides the
  means of electrical connection between the
  components.

• A PCB populated with the
  electronic components and is a printed circuit
  assembly(PCA),also known as a printed circuit
  board assembly(PCBA).

Steps in PCB Circuit Board Manufacturing

• 1)Film Generation
• Films for all of the copper and
  soldermask layers are made from photographically
  exposed mylar.
• 2)Select Raw Material
• Industry standard 0.059" thick
  FR-4 laminate copper clad on two sides.
• 3)Drill Holes
• Through holes required are created
  from your submitted files for your PCB design,
  using NC drill machines and carbide drill bits.
• 4)Electroless Copper
• In order for the through holes to
  electrically connect to the different layers of
  the PCB,a thin layer of copper is a chemically
  deposited into the through holes. This copper
  will later be thickened through electrolytic
  copper plating.
• 5)Apply Photo-resist and Image
• To transfer the PCB design from
  the electronic CAD data to the physical circuit
  board.
• 6)Pattern Plate
• This step is an
  electrochemical process which builds copper
  thickness into the holes and onto the surface of
  the PCB.

• 7)Strip Etch
• This process takes place in
  multiple steps.The first is to chemically remove
  the photo resist from the panel.
• 8)Soldermask
• Next we coat the entire panel
  with a liquid soldermask layer.Using films and
  high intensity UV light we expose the solderable
  areas of the PCB.
• 9)Nomenclature(silkscreen)
• Next we print the reference
  designators, logos and the other information
  contained in the electronic files,onto the panel.
• 10)Surface Finish Applied
• This surface finish is used
  to protect the copper from oxidation as well as a
  site for soldering of components to the PCB.
• 11)Fabrication
• We route the perimeter of the PCB from the
  larger panel using NC equipment.
• We can assemble up to
  400mm400mm without any difficulty. We can
  provide a DFM report for all new products
  assembled at Triode.If you would like a pre-job
  review, contact us and one of our Process
  Engineers will review your products.
