PCB Fabrication Process Explained Step by Step | How PCBs Are Made | Day 3 | PCB Design Course

Welcome to Day 3 of the 100 Days PCB Design Course 🚀 In this video, we will understand the complete PCB fabrication process, step by step, exactly how it happens in a real PCB manufacturing factory. This video is based on the actual PCB fabrication flow, starting from design files and ending with a finished PCB. 🔹 What you’ll learn in this video (as per fabrication flow): ✔️ Product idea → PCB design overview ✔️ Role of E-CAD: Schematic PCB Layout Stackup ✔️ Layout QA / DFM checks: Fabrication checks Manufacturability & reliability ✔️ Gerber files: Copper layers Non-copper layers 🧱 PCB Fabrication – Step-by-Step Process: 🔸 Pre-Production (P1) ✔️ Material selection ✔️ Core & prepreg selection ✔️ Copper thickness selection 🔸 Production (P2) ✔️ Photo tool & printing ✔️ Photoresist coating ✔️ UV exposure ✔️ Etching process ✔️ Chemical cleaning 🔸 Plating & Drilling (P3) ✔️ Mechanical drilling ✔️ Laser drilling ✔️ Desmear process ✔️ Electroless copper plating 🔸 Masking & Finishing (P4) ✔️ Solder mask application ✔️ Silkscreen / legend printing ✔️ Surface finish: ENIG HASL Immersion Tin 🧪 Final Quality Checks: ✔️ Electrical testing ✔️ Visual inspection ✔️ Finished PCB ready for assembly 🎯 Who should watch this video: PCB design beginners Electronics & Electrical Engineering students Hardware & manufacturing engineers Anyone who wants to understand how PCBs are actually made 📌 What’s coming in the NEXT video (Day 4): We’ll start real PCB design by creating an ESP32-S3 based board in Altium Designer, and I’ll explain the design perspective, schematic creation, and important PCB considerations inside a CAD tool. 👉 Subscribe and turn on notifications so you don’t miss it. 💬 Comment “FAB” if this video helped you understand how PCBs are actually made 👇
