Printed circuit board (PCB) technology, or PCB, has become a vital part of modern electronic devices. The global market value for bare PCBs was over $60 billion in 2014 and is estimated to reach $79 billion by 2024. These figures show that PCBs will continue to grow in importance. Nowadays, PCB technology is used in everything, but the simplest electronic devices. Some electrical products, like passive switch boxes, also use PCBs technology.
