A printed circuit board, or PCB, is used to mechanically support and electrically connect electronic components using conductive pathways, tracks or signal traces printed using Auto-lab on copper conductive sheets and PTH. In the recent past, the printed circuit boards are used in virtually all but the simplest commercially produced electronic devices, and allow fully automated assembly processes that were not possible or practical in earlier era tag type circuit assembly processes. Consumers are driving industry growth with a desire for cool products. Great technology is no longer enough to differentiate a product. It must be squeezed into a "cool" package in order to sell. This has an effect on everything inside the box – including the PCB, the chips and what's packaged on the chips.
