The above milestones in the history of printed circuits design and manufacturing have undoubtedly played significant roles in bringing the industry to the present. As with most historical examinations, there are some facts that seem to be elusive. Although there is no clear consensus on a specific answer, there are solder mask considerations that support the green color.
All About Tempo Watch Now. Now, we know how printed circuits reached their present state, but what about the future? Based on current trends, it is safe to assume that PCB production will continue to grow as demands increase and artificial intelligence AI hardware products expand.
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.

Before the end of the war, the first mass deployment took place in the Far East. In , the public also learned about the idea of the printed circuit. The triumphant march of the printed circuit board began, especially since the principle of mass soldering by solder wave was developed at that time.
This was another important prerequisite for low-cost mass production of electronics. But Eisler did not achieve much and nor did Harold V. Strong have the financial success he had hoped for at the beginning. His company Technograph marketed the licences for printed circuit boards. Eisler, although being a member of the board of the company, did not become a rich man, because a monopoly for printed circuit boards could never be achieved.
Today, countless quantities of printed circuit boards are produced all over the world. Even though they are getting smaller and smaller, a modern mass production of electronic devices would be unthinkable without the printed circuit board. The American electronics industry took up the idea of the printed circuit board in the s and rapidly developed it further.
In the mids the invention returned to Europe as German companies also began producing printed circuit boards in Eisler, initially still on the board of Technograph, left the company in He was less bitter about the lack of financial success than he was about the fact that he was not given the honour he deserved: to be the creator of one of the most important inventions of the century.
It was not until that he was recognised as the inventor of the printed circuit board. The last significant honour was bestowed on him even later. These holes took up valuable real estate that was needed for additional circuit routing. 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.
