The following points are to be observed while forming the layout of P.C.B.

Between two components, sufficient space should be maintained.

High voltage/max dissipated components should be mounted at sufficient distance from semiconductor and electrolytic capacitors.

The most important points are that the components layout is making proper compromise with copper side circuit layout.

     ; ; ; Printed circuit board (P.C.B.s) is used to avoid most of all the disadvantages of conventional breadboard. These also avoid the use of thin wires for connecting the components; they are small in size and efficient in performance.

First of al the actual size circuit layout is to be drawn on the copper side of the copper clad board. Then enamel paint is applied on the tracks of connection with the help of a shade brush. We have to apply the paints surrounding the point at which the connection is to be made. It avoids the disconnection between the leg of the component and circuit track. After completion of painting work, it is allowed to dry.
