, Concepts of PCB Design
• An electronic equipment is a combination of electrical and electronic components connected to prod
a certain designed function.
• The printed circuit board provides both the physical structure for mounting and holding electronic
components as well as the electrical interconnection between components.
• The printed circuit board is usually abbreviated as PCB
Advantages of PCBs
i.The size of component assembly is reduced with a corresponding decrease in weight.
ii. Quantity production can be achieved at lower unit cost.
iii. Component wiring and assembly can be mechanized.
iv. Circuit characteristics can be maintained without introducing variation in inter-circuit capacitance
v. They ensure a high level of repeatability and offer uniformity of electrical assembly to assembly.
vi. The location of parts is fixed, which simplifies identification and maintenance of electronic equipm
and systems.
vii. Inspection time is reduced because printed circuitry eliminates the probability of error.
viii. Printed wiring personnel require minimal technical skills and training. Chances of miswiring or s
circuited wiring are minimized.

, Components of a Printed Circuit Board
The essential components of a printed circuit board are:
• The base, which is a thin board of insulating material, rigid or flexible, which supports all
conductors and components; and
• The conductors, normally of high purity copper in the form of thin strips of appropriate shap
firmly attached to the base material.
• The base provides mechanical support to all copper areas and all components attached to the
copper. The electrical properties of the completed circuit depend upon the dielectric propertie
the base material and must therefore, be known and appropriately controlled.
• The conductors provide not only the electrical connections between components but also
solderable attachment points for the same.
