Humans have shown extensive progress and have lifted themselves
from the violent animal to civilized persons. Machines played a very vital part
in doing so. Machines make our work easier and they reduce effort and time
greatly. We are surrounded by the machines these days and most of our work is
done by machines or by the help of the machines. There is constant up gradation
in the technology of machines and new, faster, reliable and technologically
superior machines are coming into the market. Most of the machines these days
are electrically operated, for example computer. It is a very essential device
which is used by almost every office no matter; it is private organization or
government offices. We cannot imagine the human existence this time without the
help of the machines.
Printed circuit
board solved problems of the conventional circuits as they rarely got short
circuited -
In the past, the
conventional circuits were used for making wiring in the machines. There used
to be the protracted process of point to point wiring. For the big machine this
wiring used to be very messy and wire junction used to get damaged while
operating the machine for long time. These frequent short circuits used to cause
early damage of the insulation of the wires. The insulation used to crack due
to short circuits. Printed circuit boards gave the perfect solution of this
problem. In the past, electronic devices used to fill large space and this used
to make it very uncomfortable to move them. The printed circuit boards drastically
help in reducing the size of the electronic devices.
The composition to
better understand the printed circuit board -
The printed circuit board is a sheet and on this sheet which
provides the platform to connect the components, the integrated circuits are
attached. The thin strip of the conducting material which is copper in most of
the cases is fixed to the sheet, and this sheet is attached with the insulated
bottom sheet. The components are connected by this thin strip of conducting material.
The metal is known as the Solder which connects the electrical components to
the printed circuit board surface. The insulating sheet imparts the required
mechanical support and strength to this board along with it; this makes the
safe, secure connection among components easy by the conducting material. This
circuit is slim in structure and this kind of coating mold this whole circuit
in a single object.
Manufacturing of
these printed circuit board circuits and their use in various machines -
Theses printed circuit boards are very helpful and are
replacing the old and conventional circuits. They are widely used in many
devices like TV, led screen, devices which are used in hospital, offices, etc.
The printed circuit boards have created a kind of revolution because these
circuits are reliable and last very long. There are various manufacturing
companies which are making these circuits for the different devices and
embedding these circuits in the various devices.
