Introduction
Double sided circuit board means has a double-sided copper, and metallized holes, that is double-sided copper, and copper are holes inside
Both sides have double wiring board, but to use the wire on both sides. Both sides must be in the room with appropriate electrical connections. "Bridge" between this circuit called vias. Guide hole in the PCB, metal filled or coated with holes, which can be connected to the conductors on both sides. Because dual-panel area twice as big than the single panel, double panel to solve the single-panel wiring staggered because of difficulty (can be turned to the other side of the hole), it is more suitable for use in more complex than single-panel circuit.
Advantages
Compared with single-board: wiring convenient, simple, labor-intensive wiring smaller, shorter line length.
Double Circuit Board Design Steps
1. Prepare circuit schematics
2. Create a new file and loaded PCB component package library
3, planning board
4, into the network table and components
5, automatic layout components
6, layout adjustment
7, the network density analysis
8, wiring rules set
9, automatic routing
10, manually adjust the wiring
