The assortment of devices and gadgets people today enjoy is truly amazing. Many of these consumer electronics are diverse and functional enough to allow their owners to conveniently complete their daily tasks. The great demand for these multi-function devices has made competition among their manufacturers fiercer. In all these developments, the consumers definitely have a lot to gain.
Cellphones, for instance, are devices that people today cannot live without. They have made communicating and even working while on the go possible. According to the United Nation’s telecommunications agency, there are almost as many cellphone subscriptionsas there are people on this earth – that’s 6.8 billion subscriptions out of the global population of approximately 7 billion. It took over 20 years for the subscription figures to grow and all the while the engineers and developers continue to enhance every aspect of these gadgets to come out with better models that are more responsive to the consumers’ needs.
As thin and sleek as most of today’s cellphones are, it would not come as a surprise that all their functionalities rely on a printed circuit board embedded in their systems. The use of these boards is actually what made it possible for today’s cellphones to be light and small. These are self-contained modules of interconnected electronic components that embedded in various communication devices like pagers, radios, and radars. The earliest PCB’s were manufactured using raw materials such as layered cardboard, Bakelite, Masonite, as well as wooden planks. As the capabilities of printed circuit board ssignificantly improved the performance of most electronic devices, the demand to innovate the design of the old circuit board came.
The ordinary insulated wire is considered to be the most distant ancestor of the printed circuit board. This is the reason why transitioning to the use of circuit boards is referred to in the design community as going from lien to plate. Today, PCBs are smaller in size are printed in thin green “cards” to hold the various parts like the transistors, resistors and IC chips that act as the lifeblood of almost all digital technologies. Through this advancement, manufacturers placed more components in our cellphones to deliver the features that allow access to the virtual world such as Wi-Fi connections, online messaging, and e-mail.
Apart from mobile phones, printed circuit boards are used in both desktop and laptop computers. They provide support for many internal computer components, such as video cards, controller cards, and expansion cards. The following components all connect to the motherboard as well as the printed circuit board.
There are different types of PCBs that consumers and manufacturers can choose from depending on the requirements of their devices. This classification is also needed since the layout and design of a printed circuit board can become complex. That’s why engineers have to determine whether they are going to use single-sided, double-sided, or multi-layered PCBs.
Single-sided PCBs are used for basic electronics. In the ordinary configuration of electronic devices like computers, tablets, smartphones and microwaves, there exists a higher degree of complexity with their functions, though there are few instances of single- sided boards being used.
Double-sided PCBs are made from a sturdier material called R-4 that exhibits mechanical and electrical properties. These boards are used for functions that require bigger capacity.
Multi-layered PCBs are excellent when it comes to capacity. Compared to the others, these circuit boards offer better options for routing. The signals are also better and multi- layered printed circuit boards do not have noise associated with them.
There is no denying that printed circuit boards play a great role in the way people today are enjoying their devices. They form the foundation of consumer electronic devices and gadgets that go beyond primitive roots to the age of connection and communication. They may be small and thin but the way they pack power into modern devices definitely tops heftier parts.
