What is PCB design?

PCB design refers to the process of designing and creating printed circuit boards (PCBs) which are used to connect electronic components in devices such as computers, smartphones, and other electronic devices. The process involves using computer-aided design (CAD) software to lay out the components and connections on the board, and then using various manufacturing techniques to produce the physical PCB. PCB design includes several steps, including schematic capture, PCB layout, and PCB fabrication.

PCB design process

The PCB design process typically includes the following steps:

Schematic capture: This step involves creating a diagram that shows the connections between the various electronic components on the PCB. This diagram is used as a guide for the PCB layout.

PCB layout: This step involves using CAD software to create a physical layout of the PCB, including the placement of components, routing of connections, and design of power and ground planes.

PCB fabrication: This step involves using various manufacturing techniques to produce the physical PCB. This can include etching, drilling, and lamination.

PCB assembly: This step involves populating the PCB with electronic components, and soldering them in place.

PCB testing: This step involves testing the PCB to ensure that it is functioning correctly and that there are no errors or defects.

PCB finalization : This step involves finalizing the PCB by adding silkscreen, legend, other markings and final packaging.

It is important to note that not all PCB designs are the same and the steps may vary based on the complexity and intended use of the PCB.


PCB routing is the process of laying out the electrical connections on a printed circuit board (PCB) using computer-aided design (CAD) software. It is a critical step in the PCB design process as it determines the final layout of the PCB and the routing of the electrical connections between the various components.

During routing, the designer will use the CAD software to connect the various components on the PCB by creating pathways, or traces, for the electrical current to flow through. The routing process may include the use of various routing tools such as auto-routers, manual trace placement, and interactive routing tools.

The routing process also involves the consideration of various factors such as the trace width and spacing, the presence of power and ground planes, and the overall layout of the PCB in order to ensure that the PCB will function as intended and that there are no electrical interference or signal integrity issues.

It's important to note that PCB routing is a complex process that requires a combination of technical knowledge and experience, especially when it comes to high-speed and high-density designs.


ECAD-MCAD integration is the process of linking electronic design data (ECAD) with mechanical design data (MCAD) in order to create a complete product design. ECAD refers to the electronic design data used in the creation of printed circuit boards (PCBs), while MCAD refers to the mechanical design data used in the creation of the mechanical components of a product, such as the housing or enclosure.

The integration of ECAD and MCAD is necessary because electronic components are often integrated into mechanical devices. This integration allows design engineers to ensure that the mechanical design can accommodate the electronic components, and that the electronic components will function correctly within the mechanical design.

The integration process may include the use of specialized software that allows for the seamless exchange of data between ECAD and MCAD, and for the simultaneous design and editing of both electronic and mechanical components. This can help to reduce errors and improve overall design efficiency.

It's important to note that ECAD-MCAD integration also includes the validation of design compatibility, thermal analysis, electromagnetic compatibility (EMC), and other critical aspect of the design that affects both electronic and mechanical design.
