history of electric board circuits

When we think about the electrical devices that make our lives work, such as cell phones, TVs, computers and washing machines and even cars, we often don’t realize how much they rely on the tiny traces on printed circuit boards. These conductive pathways, known as “traces,” connect different electronic components like diodes, resistors and capacitors to perform their specific tasks.

These conductive pathways are made of copper and other substances that conduct electricity. As the need for electronic devices increased, so too did the desire for more efficient internal systems to enable the flow of electricity. In the beginning, these were made of wires that connected different parts of a device with wires running across the device. While these were functional, they required a great deal of labor and tended to malfunction under stress.

In the early 1800s, one inventor created a electric board circuit with fixed contacts to allow the transfer of electricity with less resistance. However, this wasn’t a practical system for constructing a larger scale circuit because it had no insulating materials to keep the electric currents contained. In addition, these fixed contact systems did not provide an effective way to distribute the current evenly throughout the device.

Can you describe the history of electric board circuits?

The evolution of the modern-day circuit board began in the 1930s when an engineer named Paul Eisler developed a more advanced version of his earlier invention. Using his experience with printing, he conceived of the idea of adding a layer of copper foil to an insulating material so that conductive patterns could be printed on it. The idea caught the attention of both the American and British military who adapted this technology to use proximity fuses in mines, bombs and artillery shells during WWII.

After the war, these advances were quickly adopted into consumer electronics such as digital watches and alarm clocks. By the 1980s, PCBs were being used in desktop computers, Atari game consoles and CD and laserdisc players. Today, circuit boards are used in almost every household and workplace electronic.

While we can look back and marvel at the incredible advancements that have been made in electronics, it’s important to remember that these innovations are built upon a foundation of basic science and engineering. The physics of electrical current is what drives all of this and it’s important to understand the fundamentals of AC and DC power before we can begin to design for the future. If we are to build a more sustainable world, the next generation of power will need to be produced using renewable energy sources that produce direct current (DC) that can easily be converted into alternating current for our appliances and devices. This will require a new generation of power converters that are more compact and can deliver the same performance as our existing power converters. We can’t wait to see what the future holds for our world of electronics!
