LEAPPCB taught you how to draw simple PCB circuit diagrams in seven steps

The PCB design principle can be divided into seven steps.

(1) after the Protel 99 / Schematic design drawing size, design drawing is necessary, set the appropriate size of the drawings, the so-called right drawing is according to the size of the circuit diagram, the appropriate drawings

Size is the basis of a schematic diagram.

(2) set up the Protel 99/Schematic design environment. The environment design mentioned here includes setting the size and type of the lattice, the type of cursor, etc., of course, the majority of parameters can be used by default.

(3) the rotating part user shall take the parts from the parts library and place them into the drawing according to the needs of the printed circuit board diagram, and define and set the serial number of the parts and the packaging of the parts.

(4) there are various tools provided by Protel 99/Schematic to make the components of the drawing to be connected with electrical wires and symbols to form a complete Schematic diagram.

(5) the adjustment circuit will make the preliminary drawing of the circuit diagram for further adjustment and modification, making the schematic diagram more beautiful.

(6) report output generates a variety of reports through various reporting tools provided by Protel 99/ Schematic, the most important of which is the network table, which is prepared for the subsequent circuit board design through the network table.

(7) the final step of document saving and printing output is to save and print the output.
