RECOMMENDATIONS:

PCB is used to connect electronic compnentsusing conductive pathways.

Generally it is best to place parts only on the top side of the board. When placing components, make sure that the snap-to-grid is turned on,a value of 0.050" for the snap grid is best for the job.

Give careful thought when placing components to minimize trace lengths. Puts parts next to each other that connect each other .Dong a good job here will make laying the tracks much easier.

Arrange ic in only one or two orientations: up or down and right or left align aches so that pin one is in the same place for each orientation, usually on the top or left sides.
