THE DESIGN AND DEVELOPMENT OF PCB FOR AUTOMOTIVE RELAY SYSTEMS
VARUN VYANKATESH MACHHA
In modern vehicles, relay systems are used to control different electrical components such as headlights, cooling fans, horns, and fuel pumps. Traditionally, these systems require a large amount of wiring, which can increase complexity and maintenance. This project focuses on designing and developing a Printed Circuit Board (PCB) for an automotive relay system to make the circuit more compact, organized, and reliable. The PCB was designed by selecting suitable components, creating the circuit layout, and testing the final board under different operating conditions. The developed system successfully controlled electrical loads through relays and showed stable performance. The project demonstrates how PCB technology can improve the efficiency, safety, and reliability of automotive electrical systems.
