To start off with, one of the biggest advantages of a Printed Circuit Board is how small they are. They are not just tiny but allow for a large number of components to be included within them.

Furthermore, they are much more reliable than electronic device circuits as they are less number of individual components. http://printedcircuitboard.mystrikingly.com/blog/pcbs-an-ideal-choice
