What is Electronics | Introduction to Electronics | Electronic Devices & Circuits

Electronics deals with electrical circuits that involve active electrical components such as vacuum tubes, transistors, diodes, integrated circuits, optoelectronics, and sensors, associated passive electrical components, and interconnection technologies.

What is Electronics? | The word electronics is derived from electron mechanics which means to study the behavior of an electron and the different conditions of the applied electric field.

The device which controls the flow of electrons is called an electronic device. These devices are the main building blocks of electronic circuits.

The motion of electrons through a conductor gives us electric current this electric current can be produced with the help of batteries and generators.

Branches of Electronics | Electronics have various branches include:

Digital electronics
Analog electronics
Micro-electronics
Nano-electronics.
Opto-electronics
Integrated circuit
Semiconductor device

History of Electronics | Let's look into the history of electronics.

The diode vacuum tube was the first electronic component invented by Jay a Fleming later Leedy frost developed the triode a three-element vacuum tube capable of voltage amplification.

in 1947 Bell Laboratories developed the first transistor based on the research of Shockley Bardeen and Brattain.

In 1959 Jack Kilby of Texas Instruments developed the first integrated circuit.

Advantages Of Electronics| Advantages of electronics electronic devices are playing a major role in everyday life.

The various electronic devices, we use in everyday life include:

Computers
Mobile Phones
ATM
Pendrive
Television
Digital camera etc

Printed Circuit Board Explained! || How Do PCBs Work?

2020-05-25T04:39:00.000-07:00

Printed Circuit Board (PCB) Explained | How are PCBs made, how do they make modern electronics possible, and is it ever OK to drill through them to mount a cooler...

So, you just bought a shiny new motherboard and after you're done looming and eyeing over the heatsinks that say extreme gamer.

That is designed to look like a battle-ax or whatever you might have noticed all those tiny traces on the board that connect all of your ports headers and sockets together and actually make the board light up and function correctly and although they're not particularly exciting.

How Do PCBs Work?

Traces on printed circuit boards or PCBs have basically made all of the modern electronics possible. In fact, before they became widespread in the latter half of the 20th century connecting every electrical component inside of an appliance looked a little something like this:

A huge mass of individual wires. This is actually a look inside of a TV from 1948 and you imagine trying to build a computer or even buy a flat panel TV if you had to deal with that!

Fortunately, the idea of embedding wires in a flat piece of fiberglass really took off as the years went by making it possible to fit a PC in a backpack instead of a giant cabinet, but how exactly then do they pack so many important connections in such a small space.

The process is actually somewhat similar to how CPUs are manufactured? Which you can learn more about in this Article

I'll be it add a bit of less complicated scale.

Slices of fiberglass are stacked together and treated with a resin makes them stick to each other to make one solid slab.

Then layers of copper are applied to both sides and coat it in a chemical called photoresist.

After this a pattern that matches up exactly to the traces that are supposed to go on the board is placed on top.

Then the whole thing is exposed to UV light.

The board is then washed which well washes away the uncovered areas leaving tracks of copper these tracks serve as a base for how the PCB will ultimately look after a couple of more steps including:

Catching additional copper and more washing but keep in mind that this process is often done in layers which is why it's a terrible idea to try and drill through your motherboard

If you're having trouble mounting a cooler to it. The Internet has more than a few tales of people that tried to do this only to find out that their board didn't work at all.

Afterward because they drilled in the middle of traces that were visible from the outside but went right through ones that were inside of it but that isn't to say that boards don't get drilled at all during manufacturing.

At the factory boards not only get mounting holes drilled through them for whatever form factor they happen to fit in but they also get small holes to accommodate connections for small electrical components like chips capacitors and resistors as well as tiny interconnects between the different layers of copper traces.

So after things like PCI Express slots heat sinks and CPU sockets are mounted or soldered to the board it's basically finished.

But since a PCB is just a collection of electrical connections on some kind of a substrate you don't actually need any fancy manufacturing processes to make a simple one.

In fact, you can even buy markers that will dispense electrically conductive ink onto special paper so you can literally draw your own working PCB (Pretty cool).

But given the inherent complexity in manufacturing something like an ATX motherboard. I wouldn't count on being able to make your own one of those and maybe stick to you know making LED art that you can stick to your refrigerator.
