The circuit board has been around for generations. You could just say that it is today’s microchips’ forefathers. Technically and practically speaking, those smart and sophisticated printed circuit boards, all being mass produced and distributed on a daily basis, hour by hour, may never reach the minute size and capacity that todays’ supremely advanced microchips have reached. You can hardly call it a miracle of nature.
But then again, you could. Because from where are all the parts and components, however minute they may be, coming from? From nature, of course. It is a well-known fact by now that silicon is mined. It is apparent that there are only a few areas in the world where such valuable resources are in existence. The only concern now is to ensure that the mining of such resources is done as sustainably and responsibly as possible.
The manufacture of smart printed circuit boards has already reached that point of sustainability. The principles and practices of 2 D and 3 D printing have very little impact on carbon use. Of course, no commercial environment can say truthfully that it has reached the point of carbon neutrality. But going forward, there is every possibility that this will be inevitable. It is only a matter of time, the question being, just when.
Nevertheless, while circuit boards can never reach the tiniest microchip size, they are getting a lot smaller. This, of course, is highly convenient for any commercial or private user. You will already have noticed this in the everyday use of your devices, many of which are now handheld. And if you were a curious but intelligent monkey, you could prize open a device and there you would find it. The circuit board.
