Classification of PCB
The single panel (Single-SidedBoards) on the most basic PCB (Printed circuit board company), the parts are concentrated in one side, the wires are concentrated on the other side. Because the wires only appear on one side, the PCB is called a single panel (Single-sided). Because the single panel has many strict restrictions on the design circuit (because only one side, the wiring cannot cross and must move around the individual path), only earlier circuits use such boards.
Double sided plate
Double sided board (Double-SidedBoards), both sides of this circuit have wiring, but to use the two sides of the wire, there must be between the two sides have proper circuit connection. The bridge between such circuits is called the via.
In order to increase the area to be wired, multilayer boards use more single or double sided wiring boards (Multi-LayerBoards). With a double and two single block as inner layer as the outer layer or two double-sided printed circuit board for the outer layer of the inner layer, two single block, through the positioning system and an insulating adhesive material alternately printed circuit board according to the design requirements for interconnection together and the conductive pattern becomes the four layer, six layer printed circuit board (china Pcb design company), also known as for multilayer printed circuit board.
