The process of making a PCB (printed circuit board) typically involves the following steps:

1. Design: The first step is to design the circuit schematic and layout of the ELE PCB using specialized software such as Eagle, Altium, or KiCad.

2. Printing the PCB layout: The PCB layout is printed onto a transparent film or paper, which is then used as a template for transferring the design to the PCB.

3. Transferring the design: The PCB layout is transferred to the copper layer of the PCB using a specialized transfer paper or film. The transfer process can be done using a hot iron or a laminator.

4. Etching: The PCB is then etched using a chemical solution such as ferric chloride, which removes the copper not covered by the transfer material. This creates the traces and pads that make up the circuit.

5. Drilling: Holes are drilled in the PCB for mounting components and making electrical connections.

6. Plating: A thin layer of copper is deposited onto the PCB to reinforce the traces and pads.

7. Solder mask: A solder mask is applied to the PCB to protect the copper and prevent unwanted solder bridges between components.

8. Silkscreen: A layer of white ink is applied to the PCB to label components, indicate polarity, and provide other information.

9. Quality control: The PCB is visually inspected, electrically tested, and any errors are corrected.

Overall, the process of making a PCB requires attention to detail, specialized equipment, and knowledge of electrical engineering and PCB design principles.
