2. Material Handling
   A base material, often a rigid substrate like FR-4 (a fiberglass epoxy laminate), is selected. This material is coated with a thin layer of copper on one side.
3. Imaging
   A photoresist layer is applied over the copper surface. Using a photolithographic process, the circuit pattern is transferred to the photoresist. This involves exposing the resist to UV light through a film mask of the PCB design, which hardens the exposed areas.
4. Etching
   The unhardened photoresist is then washed away, and the board is submerged in an etching solution. This chemical process removes the exposed copper, leaving behind the desired copper traces that form the circuit.
5. Drilling
   Holes for component insertion and mounting are precisely drilled using automated machines. These holes are drilled according to the PCB design specifications.
6. Solder Mask Application
   A solder mask, typically a green protective layer, is applied to the board, exposing only the areas intended for soldering. This mask prevents solder bridges and protects the copper traces.
7. Silkscreen Printing
   Component labels and other designators are printed on the solder mask using a silkscreen process, aiding in assembly and testing.
8. Surface Finish
   A final surface finish, such as HASL (Hot Air Solder Leveling) or ENIG (Electroless Nickel Immersion Gold), is applied to the exposed copper pads to prevent oxidation and ensure good solderability.
9. Quality Control
   Each board undergoes a thorough inspection for dimensional accuracy, connectivity, and overall quality. Electrical tests may also be performed to verify functionality.
