Development of the Printed Circuit Board Over Time
History of the Printed Circuit Board
The printed circuit board was originally created in the 1940s. Over its first 50 years, it continued to develop and gain momentum across the world. By 1995, it had already reached the billions as an industry. To be exact, the circuit board industry reached $7.1 billion that year. By 2000, it had exceed around $10 billion as an industry. A little over 12 years later, in 2012, the industry become worth $60 billion across the globe.
Design of the Circuit Board
In early variations of the printed circuit board, clear Mylar sheets were used to design the circuit board. This was because the proper printed circuit board software was yet to be created and introduced to the world. The clear Mylar sheet were much larger than what the circuit board would be when completed. In fact, they were around four times bigger than the circuit board.
Now, with the right software created, board designers can create circuit boards with much more ease. They generally use a computer-aided design system that allows them to create the circuit pattern. With this software, the spaces are now .04 inches or smaller between the electrical conducting paths.
Advent of Machine-Assembly
As the industry continues to change, so does the way the prototype assembly of the printed circuit board comes to be. For instance, pcb prototype assembly companies are now using machine-assembly. This means that, in some cases, it doesn?t matter what the size of the order is. With machine-assembly, they can assembly printed circuit boards much quicker. Hand placement would make it nearly impossible to complete extremely large orders of printed circuit boards. On average, the turnaround now can be around 75% quicker.
Miniaturization of Transistors
Another goal in the printed circuit board industry is to continue to decrease the size of the transistors. Eventually, the goal is for them to be the size of a single nanometer. If transistors could reach that size, that would be like 10 atoms back-to-back.
Now that you?ve learned more about the printed circuit board?s history and how it has developed over the decades since its introduction, you can appreciate how much work has gone into making this piece of technology as useful as possible for society.
