It is also likely that ELIC and embedded components will continue to transform PCB design, while new materials will lead to more printable components. It is also probable that Internet of Things IoT manufacturing, where PCB manufacturing is automated and completely software driven, will affect the types of products designed and developed and revolutionize the way boards are manufactured.
You might have been surprised by some of the incredible developments in the history of printed circuits. The future undoubtedly has more in store. At Tempo Automation , we are committed to not only being on the cutting edge of PCB manufacturing but also helping to shape that future.
Our white box approach to PCB design and development, which optimizes the combination of design intent and manufacturing capability, is one way we implement this leadership. And to help you get started on the best path to optimizing your development process, we furnish information for your DFM and enable you to easily view and download DRC files.

Danko develop auto-assembly process. SMT components were developed, and quickly became the manufacturing standard, that were soldered directly onto small pads on the PCB, without needing holes. SMT components proliferated quickly becoming the industry standard, and worked to replace through hole components, again improving functional power, performance, reliability as well as reducing electronic manufacturing costs.
Computerization design automates many steps in PCB design, and facilitates increasingly complex designs with smaller, lighter components. The component suppliers work simultaneously to improve the performance of their devices, reduce their electrical consumption, increase their reliability, while at the same time reducing cost. Smaller connections allow for rapidly increasing PCB miniaturization. Multi-layered and flexible circuit PCB designs allow for vastly more operational functionality in electronic devices, with increasingly smaller and lower cost PCBs.
This is largely due to the phasing out of chemical PCBs over the past four decades. The terms printed circuit board and printed wire board PWB are now used interchangeably in the industry, though printed circuit board is now the more common term. As printed circuit boards continue to evolve, they can be expected to grow ever smaller and more complex.
The latest innovation in PCB technology—the rigid flex PCB —combines the complexity and reliability of a hardboard circuit with flexible layers that are incorporated into the rigid structure. With these combined layers, rigid-flex PCBs are smaller, thinner and can fit into unusually shaped or especially small products. The intellectual father of the printed circuit board was Paul Eisler. If he had only asked for a few pennies for each copy of his invention, he would have amassed a fortune greater than that of Bill Gates however, he did not.
Although the Austrian-born inventor came up with the brilliant idea for the most important invention of this century, he had to fight for recognition for many years. Eisler, who studied engineering, had worked as an editor of a magazine during his studies.
Even then, printing on paper gave him the idea that this process should enable more than just the mass production of newspapers. In his cramped one-room flat in the London suburb of Hampstead, he had his first idea.
The construction of the radios of that time used tubes, resistors and coils that were still connected with individual wires. Eisler, on the other hand, wanted a clean system of conductor lines on one level. Something that could be printed, something that would be the basis for a mass production process.
Eisler experimented vigorously and registered his first patent in , a precursor to his main patent that describes the first real printed circuit board. He presented his idea to the English radio manufacturer Plessey.
Countless women worked there to connect the complicated wire bundles. In , at the beginning of the war, he found a patron in the wealthy owner of a printing house named Harold V. During a taxi ride, Eisler confidently signed the contract and transferred the rights to his invention to Strong for one English pound sterling.
As obvious as the military use of the invention was, the British Ministry of Defence at the time was opposed to its use. The consequence: no private company dared to take up the idea and develop it further.
