PCB Fabrication is the process of creating printed circuit boards, which are essential components in electronic devices. This process involves several steps, including designing the circuit layout, etching the copper layers, and applying protective coatings. The goal is to create a reliable platform for connecting electronic components. Once the design is finalized, the fabrication process begins with layering materials like copper and fiberglass. These layers are then processed to form the desired circuit patterns. Afterward, holes are drilled for component placement, and the board is tested for quality before being sent for assembly into electronic devices.
