Some of the earliest electronic devices were rather large and cumbersome simply because of the amount of components that were required to run them. The housings had to be made large enough to encase all of the vacuum and picture tubes, resistors, capacitors and an incredible amount of wiring. Fortunately, the evolution of printed circuit boards has made it possible to develop devices that are much smaller and more efficient. Early in the 1900s, people began filing for patents on the concept of PCBs, though no one created a fully functional device until the year 1943. With this successful creation, the technology quickly began to evolve and devices were produced with more compact and effective designs that functioned more efficiently and required less space. As time passed, improvements were made and today these boards are used to power items as complex as a computer as well as those as simple as electric razor. They are built by beginning with a flat board, also known as a substrate, that is made from a substance such as fiberglass that has insulating properties. The surface is coated with a conductive metal into which the pathways by which the electricity will flow are etched, eliminating the necessity of bundles of wires. Other components are inserted into the holes that are drilled in the surface, and soldered in place for stability. This style of circuitry is highly versatile and has many practical applications. Without the need to house tubes or accommodate a labyrinth of wires, they can be created to provide power for the smallest of electronic devices. There are several other advantages that this compact and adaptable product has to offer. They are also the preferred choice for power source because of their durable nature. The absence of glass tubing or looping wires eliminates the chance that something may be shattered or pulled off since all the necessary components are adhered to the substrate through soldering. The upside to this is that the board is not adversely affected by shaking and movement when inserted into devices which may be subjected to such actions. Another positive point to this technology is that generally speaking, most designs follow a similar layout that places most of the components in the same place, lending a new level of ease to the diagnostic process. With the printing, all signal pathways are straight, clearly labeled and easy to trace from start to finish. Locating issues may be done much quicker because there is no risk of things being improperly wired. They are also much quieter than their predecessors, partly because there are no humming tubes. These boards are laid out so that the electrical currents travel the shortest path possible to reduce radiation and minimize the interference from electromagnetic waves. This careful design intentionally reduces exposure to factors that would ordinarily cause significant performance degradation. The many advantages to the design of modern printed circuit boards are easy to see both in general and in respect to individual devices. Production is both quicker and more affordable, with less materials being required. The field of electronic technology has made amazing strides since the implementation of the first prototype.
