Double sided Boards (Double-Sided), 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. The guide hole is a small hole filled or coated with metal on the PCB. It can be connected with the wires on both sides. Because the double sided area than a single panel doubled, double panel solves the single panel because of difficult wiring staggered (through hole conduction to the other side), it is more suitable for use in circuit is more complex than a single panel.
