    Abstract: Development of multi-layer Printed Circuit
Board (PCB) by using Eagle has been presented in this
project. The Eagle is a CAD tool comprises of Schematic
Module, Layout Editor Module, Autorouter Module and
CAM Job. The schematic module is for development
schematic. After designing the schematic, Electrical Rule
Check (ERC) would be performed for electrical errors and
consistency check between schematic and board.
Thereafter, with the help of this schematic, it needs to
create a board in the Layout Editor Module. Then the
Digital Rule Check (DRC) has to be operated for
reporting any errors in the Board like clearance errors
under the set of design rules. Thereafter, 100% finished
multi-layer (1-16) board would be created by Autorouter
with desired track size and layer. Afterwards, adding
ground and mounting holes manufacturing data have to be
generated by CAM Job and send the board house for
fabrication. Finally, the board house provides multi-layer
finished Printed Circuit Boards (PCBs). After fabrication,
the board should be assembled and tested successfully.
The testing data would be presented for functionality
characteristics.
