Product Design & Development / Printed Circuit Boards (PCB)
Printed Circuit Boards (PCB) are flat-boards upon which various electronic components are placed for mechanical support and connected through desired electrical connections to develop conductive circuits. PCBs are found in virtually all electronic devices and help in implementing any functionality based on the arrangement and connections among the different electronic components. Components can be connected on the PCB through conductive paths or etched copper wiring on a non-conductive substrate such as plastic. A PCB that has been assembled with such electronic components through appropriate connections is known as a Printed Circuit Assembly (PCA) (Khandpur, 2007).
