How are Printed Circuit Boards made?

Printed Circuit Boards or PCB for short, is a plastic board that is created for connecting electronic components and parts together. They are commonly used in all types of electronics, from computers to digital clocks. The board itself is not a conductive material and often plastic or fibre glass is used as the base material. The primary use of PCBs is to control where the electricity is directed to.

There are three main types of circuit boards; single-sided, double-sided and multi-layered.

  • A single-sided board has the components and parts on one side of the substrate.
  • A double-sided board contains more components than the single-sided board and therefore uses both sides of the substrate. Electrical connections between the two sides are made by drilling holes in the appropriate places.
  • A multi-layered board consists of a substrate which is made up of multiple layers of printed circuits. These printed circuits are separated by layers of insulation.

Circuit boards can have a variety of parts that are connected and work together. Each board is unique as they have different uses and functions.

Here are the main stages which circuit boards undergo when being created:

 

Designing

The very first step in creating a printed circuit board is the designing of the board. Similar to all manufactured products, circuit boards require a plan. Depending on your requirements for the functions of the board, the PCB designer can create and design a suitable layout using industry Computer Aided Design software. Some of the most popular CAD software includes; Eagle, Altium, and OrCad.

After designing a layout for the PCB, checks will be carried out to ensure that the
