Printed circuit boards are an
integral part of any kind of electronic component or gadget. And these
electronic devices have blended in with our lives so well that we do not even
realize how important they have become not only for our convenience but also our
survival. This flourishing industry of electronics has reached out to every
other form of industry and technology. For e.g. the revolution in medical
science, aero space technology, military and automobile industry, the
applications are countless. In fact the electronics industry has been
supporting all other forms of industries to advance to new technologies.
We are surrounded by hundreds of
electronics devices everyday and each of these devices has a printed circuit
board at its heart. So what is a printed circuit board or PCB? It’s basically a
non conducting substrate sheet which has copper tracks etched on it and these
tracks converge at different junctions and nodes. The basic purpose of a PCB is
to connect various electronic components through the conducting path ways
designed on the board. Also it provides physical support to the components.
A PCB is primarily of two types.
One is the through-hole PCB where tiny holes are punched in on the nodes where
the component lead goes across the board and they are soldered on the opposite
side. It is an old technology and still in use for inexpensive circuitry
applications. One other use of these boards is to support extremely bulky
components like transformers and high rating capacitors.
The other type of PCB is the
onboard SMD PCB or surface mounted device PCB. It does not have holes instead
it has small conducting beds where the tiny SMD components are placed and
soldered using special equipments. It has higher mechanical strength and both
sides can be used for components as there are no holes. Also because the SMD
are so tiny that the circuits can be miniaturized.
It is very crucial that the
printed circuit board design is very precise and of high quality so
that the finished product is also of high quality. This is why designing of
theses boards is a very expert job and requires a lot of research and
development to make sure there are no flaws in it. Many large and small
companies who manufacture electronic components leave this job in the good
hands of the experts and outsource it to them. All they need to do is provide
them with the required specifications.
One of the biggest advantages of
availing PCB designing services is that you can get parts in bulk at
drastically reduced costs and you can be assured of the quality of the products
they are delivering at your door step. It is usually accompanied with proper
documentation of all the technical specifications and
since printed circuit board design is one of the most crucial aspect of the
PCB manufacturing, only the most reliable and trusted supplier of these board
should be hired. Conducting a proper research before hiring PCB manufactures is
a must thing to do.
