Previously, most electronic gadgets were quite uncomfortable and filled with a confusing mass of bulky components. To function properly, they needed items that consume good space, such as resistors, capacitors, bulky vacuum tubes and a complicated wiring network. The printed circuit boards completely changed the way the internal workings were assembled and allowed the products to become more streamlined.
In the early 1900s, people began to apply for patents on the concept of PCBs, although no one created a fully functional device until 1943. With this successful creation, technology quickly began to evolve and devices were produced with more designs compact and effective. which worked more efficiently and required less space. Over time, improvements have been made and today these boards are used to power items as complex as a computer, as well as those as simple as the electric shaver.
They are built starting with a flat plate, also known as substrate, which is made of a substance like fiberglass that has insulating properties. The surface is coated with a conductive metal in which the paths by which the electricity will flow are etched, eliminating the need for bundles of wires. Other components are inserted into the holes that are drilled into the surface and welded into place for stability.
Versatility is one of the many things that make this type of circuit very practical. They can be made in just about any size needed to power even the smallest devices, since there is no need for tubes and wires. The compact design is just the beginning for the multitude of advantages that are gained by using this product.
They are also the preferred choice for energy source because of its durable nature. The absence of glass tubes or elastic wires eliminates the chance that something might be broken or torn off, since all necessary components are adhered to the substrate by welding. The advantage of this is that the plate is not adversely affected by tremors and movements when inserted into devices that may be subject to such actions.
Modern printed circuit boards offer numerous advantages, some in general, others specific to the devices in which they are placed. No wonder there are so many companies offering PCB designs, prototypes, manufacturing, PCBA services and more. PCBs are much more affordable to build and take considerably less time and materials. Great strides have been made over the years that have made electronic technology more efficient and convenient.
