Printed circuit boards are an integral part of any type of electronic component or device. And these electronic devices blend so well into our lives that we do not even realize how important they have become, not just for our convenience but also for our survival. This burgeoning electronics industry has hit any other form of industry and technology. For example, the revolution in medical science, aerospace space technology, the military and automotive industry, applications are innumerable. In fact, the electronics industry has supported all other forms of industries to move to new technologies.
We are surrounded by hundreds of electronic devices every day and each of these devices has a printed circuit board in its center. So, what is a printed circuit board or PCB? It is basically a nonconducting substrate sheet that has copper bands etched into it and these tracks converge on different joints and knots. The basic purpose of a PCB is to connect various electronic components through the drive paths designed on the board. It also provides hardware for components.
A PCB is mainly of two types. One is the passing PCB, where small holes are made in the nodes where the component cable passes through the board and is soldered on the opposite side. It is an old technology and is still used for low cost circuit applications. Another use of these boards is to support extremely bulky components, such as transformers and highly qualified capacitors.
The other type of PCB is the SMD PCB on the board or the PCB of the surface mounted device. It does not have holes, but has small conducting beds where small SMD components are placed and welded using special equipment. It has a higher mechanical strength and both sides can be used for components since there are no holes. Also because the SMDs are so small that the circuits can be miniaturized.
It is very important that the the printed circuit board is very accurate and of high quality, so that the finished product is also of high quality. This is why the design of these boards is a very specialized job and requires a lot of research and development to ensure there are no flaws. Many large and small companies that manufacture electronic components leave this work in the hands of experts and subcontract it. All they need to do is provide the necessary specifications.
One of the biggest advantages of using PCB assembly services is that you can get bulk parts at a drastically reduced cost and you can be assured of the quality of the products that are delivering at your doorstep. In general, it is accompanied by proper documentation of all technical specifications and limitations of your product.
