With significant technological advancements in recent years, we are heading towards a world of smart devices that are way beyond simple functional electronics. Today the question posed is how smart can we make our devices. As we enter the realm of ambient intelligence and enhanced quality of life with better technological resources, a lot is guaranteed to change in the design and development of PCB and their Assembly.
It’s understandable to assume that PCBs have been around quite a while considering their entrenchment in the field of electronics, but the reality is somewhat different. Let’s take a look at the evolution of printed circuit boards over the years, we are sure you will be fascinated by what you find!!
Evolution of PCB’s
Below are some of the milestones that inspired other investors to build on the previous work.
- Albert Hanson invents first circuit board
It all began back in 1903 with a German pioneer named Albert Hanson who detailed flat foil conductors that were laminated in multiple layers to an insulating board. Following Hanson’s experiment, Thomas Edison went on to experiment with plating conductors to linen paper via the chemical application the following year.
- Charles Durcase creates means of electroplating circuits
About two decades later in 1927, an American inventor by the name of Charles Ducase patented a historic breakthrough in circuitry. In short, Durcase’s method was the first effective method of electroplating and entailed wiring being printed onto a board via a stencil with conductive ink. Durcase also wrote about the future of PCBs, specifically the possibility of multilayer boards.
- Paul Eisler invents the first contemporary printed circuit board
Perhaps the most important breakthrough in PCB technology came from Paul Eisler, an Austrian native displaced to England during WWII. Eisler was hard-pressed to find gainful employment and was, unfortunately, jailed under suspicion of being an illegal alien. In 1941 Eisler was released from prison and took a job with a music printing company. During his time with the company, Paul toyed with music printing equipment and modified the machines to print circuits onto boards. After a brief demonstration the company immediately invested in Eisler’s concept and began providing PCBs to Allied Forces for the remainder of the war, the US even incorporated these boards in their anti-aircraft shells.
PCBs finally came to the consumer market during the mid-1950s after the US Army developed and patented an auto-assembly process. Specifically, the Army Signal Corps is credited with the technique that allowed mass production of PCBs. The auto-assembly process effectively enabled commercial reproduction of PCBs at an advanced rate which opened the doors to the incorporation of PCBs in day-to-day household and leisure products. Following this breakthrough, printed circuit boards would go on to be an integral part of the technology used in the Apollo 11 mission. In essence, the creation of PCBs and automating their assembly was truly a giant leap for mankind.
