What is PCB Fabrication

PCB Fabrication refers to the process of manufacturing a Printed Circuit Board (PCB), which serves as the foundation for mounting and interconnecting electronic components in devices. The fabrication process transforms the circuit design (typically represented as Gerber files) into a physical board that can electrically and mechanically support components.

Key Steps in PCB Fabrication: 

• Design Verification: The process starts with the PCB layout design created using CAD software. The design is checked for errors, manufacturability, and compliance with specifications.
• Material Selection: Choose the appropriate base material (e.g., FR4, aluminium, or flexible materials) and determine the number of layers (single-layer, double-layer, or multi-layer).
• Pattern Transfer: The copper layer is coated with a photosensitive resistor, and the circuit design is transferred onto the copper using UV light (photo plotting).
• Etching: Unwanted copper is chemically removed to leave only the circuit patterns.
• Layer Alignment and Lamination: In multi-layer PCBs, individual layers are aligned and laminated under heat and pressure to form a single board.
• Drilling: Holes for vias, mounting, and component leads are drilled using CNC machines.
• Plating: The drilled holes are plated with copper to create electrical connections between layers.
• Solder Mask Application: A protective solder mask is applied to prevent oxidation and solder bridging between conductive areas.
• Surface Finish: Apply finishes like HASL (Hot Air Solder Leveling), ENIG (Electroless Nickel Immersion Gold), or OSP (Organic Solderability Preservatives) to protect copper traces and improve solderability.
• Silkscreen Printing: Text, logos, and component labels are printed on the PCB for assembly reference.
• Testing and Inspection: PCBs are inspected for defects using visual checks, automated optical inspection (AOI), or electrical testing methods.
• Final Cutting and Packaging: The fabricated PCBs are cut to the required dimensions and packaged for delivery.
