What is the PCB Fabrication Process?

The PCB fabrication process involves several steps to transform a design layout into a physical printed circuit board. Here’s an overview of the typical PCB fabrication process:

1. Design Input: The process begins with the input of the PCB design files, typically in Gerber format, along with any fabrication notes, specifications, and requirements.
2. Substrate Preparation: A substrate material, usually fiberglass-reinforced epoxy resin known as FR-4, is prepared in large sheets. The substrate is cleaned and coated with a thin layer of copper on both sides, forming the base copper layer for the PCB.
3. Photoresist Application: A layer of photoresist material is applied to the surface of the copper-clad substrate. The photoresist is sensitive to UV light and will harden upon exposure.
4. Exposure and Imaging: The PCB design is transferred onto the photoresist layer using a process called photolithography. A UV light source is used to expose the photoresist through a photomask containing the PCB pattern. The areas exposed to UV light become hardened, while the unexposed areas remain soluble.
5. Development: The exposed PCB pattern is developed by washing away the unexposed photoresist using a developing solution, leaving behind the desired copper traces and pads on the substrate.
6. Etching: The exposed copper areas not protected by the hardened photoresist are etched away using an etchant solution, typically an acidic or alkaline solution. This process removes excess copper, leaving only the copper traces and pads defined by the PCB design.
7. Photoresist Stripping: The remaining photoresist is stripped away using a solvent, leaving the bare copper traces and pads on the substrate.
8. Drilling: Holes are drilled into the PCB substrate at specified locations for through-hole components and vias. Automated drilling machines are used to precisely drill these holes.
9. Through-Hole Plating (Optional): If the design requires plated through-holes, a thin layer of copper is electroplated onto the hole walls to provide electrical continuity between layers.
10. Surface Finish: A surface finish is applied to protect the exposed copper surfaces from oxidation and facilitate soldering. Common surface finishes include HASL (Hot Air Solder Leveling), ENIG (Electroless Nickel Immersion Gold), and OSP (Organic Solderability Preservative).
11. Final Inspection: The fabricated PCB undergoes final inspection to ensure that it meets the required specifications and quality standards. This may include visual inspection, dimensional measurements, electrical testing, and other quality checks.
12. Routing and Profiling: The individual PCBs are routed out from the larger panel using CNC (Computer Numerical Control) machines, and the edges are profiled to the final dimensions.
13. Cleaning: The finished PCBs are cleaned to remove any residues from the fabrication process, ensuring the cleanliness of the board’s surface.

Once the fabrication process is complete, the printed circuit boards are ready for assembly, where components are mounted onto the board and soldered in place to create functional electronic devices.
