Abbreviated PCB, a printed circuit board is a thin slab, on which chips and other electronic components. PCB production is a very delicate and technically demanding task attention to every detail so that it can be dangerous during use. Today there is more obvious in the computer motherboard, expansion cards, control card, network interface card is used, and all other cards in principle to the PCB. There is another kind of example isflexible printed circuits, flexible printed circuit boards, SMT (Surface Mount Technology), which is mounted directly on circuit boards, etc.
Traditionally, PCBs in transformers of all types are found. May, in transformers, PCBs are used in each concentration at the end of maintenance or reconstruction. The concentration of PCBs, however, must vary in transformer stations
