What is the best PCB circuit board
Multilayer board (Multi-LayerBoards) in order to increase the area of the wiring, multilayer board with more single or double-sided wiring board. 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, also known as for multilayer printed circuit board.
The "bridge" between such circuits is called a guide hole (via). A guide hole is a small hole filled or coated with metal on PCB, which can be connected to a wire 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.
Because there are a lot of strict restrictions on the design of a single circuit (because only one side, the wiring can not cross the cross and must be around the path), so only the early circuit to use such boards. Both sides of the double-sided board (Double-SidedBoards) on both sides of this circuit board wiring, but to use both sides of the wire, you must have a proper circuit connection between the two sides.
Common multilayer board is generally 4 or 6 layers of plywood, complex multilayer board up to ten layers. So, here's a brief introduction. A single panel single panel (Single-SidedBoards) on the most basic PCB, the parts are concentrated in one side, the wire is concentrated on the other side. The PCB is called a single panel (Single-sided) because the wire only appears on one side.
PCB circuit board is the support of electronic components, is the electronic components of the electrical connection provider. According to the circuit layer can be divided into single panel, double-sided board and multilayer board.
