A photosensitive resist material is applied to the substrate, and UV light is used to transfer the circuit design onto the resist. This pattern defines the circuitry for the subsequent layers.
3. Etching: After the circuit pattern is transferred, the substrate undergoes etching to remove the unwanted metal from the exposed areas. This step creates the conductive traces and pads required for electrical connections. The etching process is carefully controlled to ensure precise patterning.
4. Lamination: Multiple layers of the substrate, including signal layers, power planes, and insulating layers, are laminated together using heat and pressure. This step creates a multi-layered structure with the desired electrical and mechanical properties. The layers are aligned and bonded to form a cohesive substrate.
5. Drilling and Plating: Vias (vertical interconnect accesses) are drilled into the substrate to allow electrical connections between different layers. The vias are then plated with a thin layer of metal, usually copper, to ensure electrical continuity. This step may include filling and plating of vias to enhance performance.
6. Patterning and Etching (for additional layers): Additional layers of circuitry are added using similar photolithography and etching processes as in the initial layer printing. Each layer is precisely aligned and etched to create the required circuitry.
7. Solder Mask Application: A solder mask is applied to protect the circuitry and prevent solder from bridging between traces during assembly. The solder mask is usually a green or other colored polymer layer that is selectively removed to expose the areas where soldering will occur.
8. Oberflächengüte:A surface finish is applied to protect the exposed copper and provide a suitable surface for soldering. Common finishes include immersion gold, nickel/gold, or solder mask.
9. Testing and Inspection: The fabricated substrate undergoes rigorous testing and inspection to ensure it meets design specifications. This includes electrical testing for continuity and functionality, as well as visual inspection for defects.

For high-density interconnect (HDI) substrates, multiple layers are used, with each layer having specific functions such as signal routing, Energieverteilung, or thermal management.
4. Drilling and Hole Formation:After lamination, holes are drilled into the board. These holes can be through-holes, blind holes, or buried holes, depending on the design. They are used for placing vias, which are necessary for connecting different layers of the PCB.
5. Electroless Plating:To prepare the drilled holes for electrical connections, they are coated with a thin layer of metal, usually copper, through an electroless plating process. This step ensures that the holes can conduct electrical signals and power between different layers of the PCB.
6. Pattern Plating:A photoresist layer is applied to the surface of the PCB, and then exposed to UV light through a photomask that outlines the desired circuit pattern. The exposed areas are developed, and the underlying copper is etched away, leaving behind the copper traces that form the electrical pathways.
7. Solder Mask and Surface Finish:A solder mask is applied to protect the copper traces and prevent solder from bridging between different connections. The solder mask is usually green but can come in other colors. Following this, a surface finish, such as HASL (Hot Air Solder Leveling), ENIG (Electroless Nickel Immersion Gold), or OSP (Organic Solderability Preservative), is applied to the exposed copper areas to enhance solderability and protect against oxidation.
8. Testing and Inspection:The fabricated PCB undergoes rigorous testing to ensure that it meets the required electrical and mechanical specifications. Tests include electrical continuity checks, impedance testing, and thermal performance evaluations. Automated optical inspection (AOI) and other quality control measures are used to detect any defects or inconsistencies.
