Evolution Of PCB In 2019, Evolution Of PCB, The history of PCB, History of printed circuit boarad, Evolution of printed circuit board, PCB evolution Hello folks, I hope things are proceeding great at all of your sides. Today I am going to discuss the evolution of PCB (Printed Circuit board) in 2019.

You all must be already aware of the term PCB, what printed circuit board is? In case you are a newbie and don’t have much information about it. Then no problem, because I am going to share the history, the evolution of Printed circuit board (PCB) and when it first comes into usage?

What is PCB?

The printed circuit board mechanically support and connect to electronic components through the use of conductive tracks, pads, and other features.

Alright, lets me explain you in simple words.

PC boards are internal components that transmit electronic signals through electronic devices. For example: whenever you turned on a TV, computer or press a button on your smartphone, you are associating with a Printed circuit Board, which are inside the enclosures of all such devices.

There are few people who are aware of the complexity of the print circuit board behind the today technology. In the absence of printed circuit board, today advanced technology would have never become possible.

History of Printed Circuit Board

  • To know in detail what PCB (Printed circuit board) is, we have to go back in History to trace the evolution of PCB. PCB has evolved in many ways since its inception.
  • First PCB patent as known as “Printed wire” were issues in the early 1900s, However, the PC boards we recognize came into use after the world war II.
  • Charles Ducas from the USA created an electronic path directly on an insulated surface by printing through a stencil with electrically conductive links.
  • Dr. Paul Eisler an Austrian scientist made the first operational printed wiring board in 1943. On that time it’s used as the replacement of massive radio tube wiring.

How earliest Printed circuit boards were made?

If you don’t know about it already then you will be amazed to know how the earliest PCB was created differently. In the 1920s they PCBs were made with different materials like  Bakelite, layered, cardboard, Masonite and even thin wooden planks. Holes were drilled into the elements and the flat brass. Wires were nailed or bolted onto the board. The component connection was usually made by the pressing of the end brass trace onto a low rivet. Small nuts and bolts were used before rivet. These types of PCBs were used in early style gramophones and radios.

In 1950 to 60’s laminates using a little different style and materials were introduced but still, PCBs were single sided. All the circuit was on the one side of the board and components was on another side of the board. PCB makes a prime choice for that time over heavy cables and wiring.  The evolution of printing wiring board came from the government agencies.

Process of Assembling Electrical Circuits

The “Process of Assembling Electrical Circuits” was then introduced by the US which developed the ways PCBs were made. In 1960, this process involved drawing the wiring patterns and then photographing it onto a zinc plate. This was the significant change and PCB starts observing a winder option. In this time PCB got more advanced in its techniques and methods. Multilayers PCBs also start producing in this time too.

In 1970, the size of the PCB begins to reduce and became much smaller. It was the time when hot air soldering methods were starting to be used. In the 1980s, the further size reduction of the PCB was made due to the outside amount of components. Within a few time, it becomes the preferred method over through-hole components. Because it requires less space and retains the same level of functionality.

The need for Computer manufacturing become the standard way for PCBs to be developed in the 1990s. Now the complexity of the circuit board increased again. This constant improvement of change enabled boards to be more effective and opened up more believable outcomes for various uses and applications. While the complexity of circuit boards keeps on expanding. The costs of the PCBs still manage to keep low.



Around 1995, this is when High-Density Interconnector PCBs were starting to be utilized. These boards include littler lines, pads and give different advantages, for example, decreased weight and size. Onwards starting here, the extra older boards become out-of-date.

Flex and Inflexible PCB

Flex and inflexible PCBs turned out to be progressively basic as they were affordable. The growth of electronic devices and gadget kept on driving PCB manufacturing change to push for effective, skilled and densely packed structures.

There are so many PCBs manufacturing companies out there and everyone is working hard with various priorities. PCBway is also striving to give customers the best product. Their PCBs are famous worldwide and I will definitely recommend them. They will give you one-on-one assistance and help you in selecting the right board for your project.  I suggest  PCBway because they offer great quality with a full range of printed circuit board capabilities and have always been satisfied.

Future of PCB

As of now, most of the circuit boards are utilizing multi-step strategies, for example, conventional vacuum deposition and photolithographic designing. Though, these techniques have barriers since they require a high handling temperature, include lethal waste, and are costly.

However, it’s not hard to imagine PCBs will be transformed in the future. It’s as of now starting! with the utilization of 3d printing become more standard ‘3d printing’ a printed circuit board has progressed toward becoming realized.
