Printed circuit boards are considered to be one of the most important elements of electronic devices as PCBs must perform precisely to make the electronic device work with accuracy and efficiency. Printed circuit boards direct and regulate the transition of electronic current through the laminated sheets and etched copper pathways, which in turn allow the electronic devices to operate accurately. The necessity of PCB testing is evident by the fact that even the slightest of fault or error in any of the PCB components can cause to major quality issue in the device.
