how to prepare PCBs at home: Explained | Basics of PCB Fabrication (chemical etching method)

Описание: This video describes the basic processes involved in PCB fabrication for those who are new to the electronics hobby, BTech and BSc basics. PCB preparation is basic and important for electronics. Main processes can be devided into:
1. Preparing the layout
2. Transferring the PCB layout into the board
3. Etching the unwanted copper using ferric chloride
4. Cleaning, drilling, soldering, and testing the final PCB

The video provides a clear, simplified view of how a raw copper board (FR4) is transformed into a functional printed circuit board using standard laboratory etching techniques.
Perfect for beginners learning how PCBs are made using the chemical etching method. It starts by explaining an example circuit that converts 12V AC to a stable 5V DC (0:40). The video then details the steps for making a PCB from a circuit diagram.
