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.

The substrate, or plate, is usually constructed of a thin piece of insulating material like fiberglass which is covered with a coat of conductive metal. Lines that are to become the paths by which the electrical ...

This circuitry is made all the more practical by the nature of its versatility. The most obvious example of this is the ability to make them small enough to fit inside some of the smallest devices because the boards do not require wiring or tubes. There are a great many advantages that have been gained by the implementation of such technology, the compact design being only one of them.

One such advantage is that of being extremely durable. All components are soldered securely onto the substrate and the absence of raise wires means there is nothing to pull loose and no tubes means no breakage. This allows the technology to be inserted into devices that may be subjected to a lot of vibration or movement without worrying about the plate becoming dislodged or shorted.

Because most circuit boards of this type follow a uniform layout with all the main components being in the same place from one design to another, they make inspections and diagnostics much quicker and easier. All of the electrical trails are clearly laid out and labeled so it is easy to follow signal paths from beginning to end. This allows for any issues to be quickly located and rectified.

No tubes means that there is no annoying humming sound being emitted. Occasionally, interference from electromagnetic waves would cause some static-type noises to occur, but since these boards are planned to have each current follow the shortest possible path, radiation and disruption are minimized. This design was done with the intention of reducing exposure to performance degrading factors.

The benefits of using printed circuit boards versus their predecessors is clearly evident by the improved performance and compact sizes of the devices they run. The cost effectiveness and conservation of materials are more positives to this option. Technology is still advancing because of this innovation.
