PCB Fabrication Technology

Learn How Circuit Boards Come to Life, Step by Step Ever wonder how smartphones, drones, or robots actually work? At the heart of these devices is the printed circuit board (PCB)—the unsung hero of modern electronics.

PCB Fabrication Technology is a hands-on, fully online course that opens the factory doors to anyone curious about how circuit boards are made.

No engineering degree required—just a desire to understand the technology that powers today’s world.

Through expert-led lectures, interactive cleanroom simulations, real case studies, and a final capstone project, you'll learn how PCBs are manufactured from raw materials to finished boards.

This course is ideal for learners who want more than theory—it's built to give you real-world insights into electronics manufacturing, all from the comfort of your home.

Inside the PCB Fabrication Process The course is organized into three major stages of PCB manufacturing, helping you gradually build both knowledge and hands-on familiarity: Material Preparation & Imaging: Get introduced to the raw materials that make up a PCB—laminates, copper foil, and prepreg.

You'll also explore how cleanroom processes and imaging techniques like photolithography are used to transfer intricate circuit patterns onto the board.

Copper Patterning & Via Formation: Dive deep into copper etching, plating, and drilling techniques.

Learn how vias are formed to electrically connect multiple layers of a board, and understand the chemistry and precision involved in creating conductive pathways.

Surface Finishing & Final Processes: Discover how boards are finished and protected.

From solder mask applications to advanced surface finishes like ENIG or HASL, this stage shows how final steps ensure reliability, durability, and functionality.

Each lecture includes practical activities such as defect analysis, yield monitoring discussions, and collaborative learning to reinforce your understanding of fabrication in real-world contexts.
