The whole process of PCB Manufacturing

From Design to Finished Circuit Board: An In-depth Journey

1. Design and Artwork Creation:

The design of the conductive layers is made with an artwork pattern of traces, planes, and other features. This design is often referred to as the “artwork”.

2. Substrate Creation:

A PCB starts with a substrate, which is a flat sheet of insulating material combined with a layer of copper foil. This is laminated to form the base for the PCB.

3. Etching:

Chemical etching is used to divide the copper into separate conducting lines called tracks or circuit traces, pads for connections, and other features.

4. Drilling:

Holes are drilled for components with wire leads to pass through. These holes can be plated-through to allow connections between different layers of the PCB.

5. Component Mounting:

Components can be mounted using “through-hole” technology where components are inserted through holes and soldered to traces on the other side. Alternatively, “surface mount” technology allows components to be soldered directly onto the PCB surface.

6. Soldering:

Components are soldered onto the board, either manually or using automated soldering processes like wave soldering.

7. Protection and Finishing:

The PCB may have a protective coating to prevent corrosion and reduce chances of solder shorts. This coating is often referred to as solder resist or solder mask.

8. Testing and Quality Control:

Once the PCB is assembled, it undergoes testing to ensure functionality and quality.
