How does PCB Fabrication work?
Design Preparation : Design specifications are prepared in Gerber format, detailing the
layout,
traces, and components of the PCB.
Substrate Processing : Substrate Processing: Substrate materials, typically
fiberglass-reinforced epoxy laminate, are
prepared for PCB fabrication.
Layer Assembly : Individual layers of substrate with copper foil are aligned and
laminated
together to form the PCB structure, especially for multi-layer PCBs.
Circuit Formation : Copper traces are created on the substrate through processes like
photoresist application, etching, drilling, and plating to achieve the desired circuit pattern.
Finishing Touches : Surface finish, silkscreen printing, and testing/inspection are
applied to
ensure the quality, reliability, and functionality of the fabricated PCBs.
