What is PCB design and how are integrated circuits incorporated into it?
A PCB consists of several key components such as circuits, dielectric layers, holes, solder resist, silk screens, and surface finishes, providing high-density, reliable, flexible, and testable designs, while integrated circuits (ICs) are small, high-performance chips soldered onto the PCB to enhance functionality and reliability.
What are the key skills required for designing PCB (Printed Circuit Boards)?
PCB board cutting, while often seen as a simple and non-technical task, requires specific skills and the use of specialized tools like scanners and high-quality conversion software to improve efficiency, accuracy, and reduce labor intensity.
