PCB Fabrication process and technology

The complete process is based on the design package that makes the circuit board in physical form.

  • The PCB fabrication process includes the transformation of circuit board designs into physical structures based upon the specifications. Generally, the data received in a Gerber file format.
  • The image data will be transformed to the board by photo tooling and direct imaging method.
  • Each layer will have to be laser printed individually.
  • The multilayer printed circuit boards are the composite of different layers of dielectric material and metal conductors.
  • Multilayer boards are available with a thinner version of the same core structure used in the manufacturing of double-sided printed circuit boards. Each layer must be controlled for copper weight, its width, and layer alignment for the final product.
  • Now, it is the time for creating the inner layer circuit images onto the inner layer cores.
  • The photoresist is exposed with either UV light or by direct laser imaging.
  • After this process, the core layers will be inspected by AOI system for any defects.
  • Each layer pair will have a sheet of "prepreg" inserted between them to facilitate the layers bonding.
  • To maintain the right alignment of circuit board on different layers requires a lot of attention. After the sandwiched layers are laminated, the heat and pressure of the lamination process will fuse the layers together into circuit board.
  • The next step of PCB fabrication is to drill circuit board holes for component mounting, through hole vias, and non-plated holes of mechanical features. That PCB design contains any buried, blind vias, or laser-drilled microvias; those are fabricated before the lamination of board.
  • Once the holes are drilled, the whole exposed board surface and the holes are chemically coated with a thin copper layer. It will create a metallic base for electroplating.
  • The solder mask is applied using a UV exposure process to protect the board. The surface finish is also applied to the circuit boards. This helps to protect the exposed metal and assists in soldering operation during assembly.
  • The last step of the PCB fabrication process is to prepare the board for assembly. The finalized boards are gone through a testing with a flying probe, or a bed of nails test fixture.
