Printed Circuit Board
(PCB) layout design is the core process in the manufacturing of circuit boards.
The designing process provides a graphical representation of the circuits and
thus gives reference to the manufacturers to work with. Further processes like
placement and soldering of electronic components and PCB assembly are all
dependant on the layout design. Thus, it is highly important to consider
certain factors while designing a circuit board.
Which
Factors should be considered in the PCB Layout Design Process?
The main aspect of
designing process for circuit boards is the manufacturability value of the
layout. Thus, as a designer, one must consider every factor involved in the
manufacturing and assembly process of PCBs. Let us have a look at such factors.
- Thickness and Width of the Circuit Board Conductor: A circuit board conductor provides path for the transmission of current. Thus, its width and thickness matters a lot in determining the amount of current that will pass through the tracks (current carrying capacity) of the PCB. As a designer, you will need to take into consideration the desired current carrying capacity and based on that, establish the width and thickness of the conductor of PCB.
- Electromagnetic Interference and Electrical Clearance: PCB layout design has to be in accordance with the electromagnetic interference between the components and tracks of the circuit board. In order to make the PCB safe for use, there should be a minimum of 8mm electrical clearance between the main as well as isolated signal tracks.
- Number of Layers in the Circuit Board: A printed circuit board could consist of a single layer or multiple layers based on its type and number of components present. For a designer, it is essential to develop a PCB layout that thoroughly describes the layers, components, their position, etc.
