The difference between a PCBA and a PCB

PCB and PCBA are basic terms used in the electronics industry.

A PCB refers to a blank circuit board, while a PCBA refers to a panel that contains all the electronic components needed for proper operation.A PCB is not yet functional because it lacks the necessary elements, but a PCBA is fully functional.

The manufacturer creates the PCBA on top of the existing PCB. therefore, PCB and PCBA are two different parts of the same process.

How do PCBAs and PCBs relate to each other?

Process:PCBA is a fully assembled PCB with all the components needed to work as intended, but the PCBA is ready for use in electrical equipment.

Cost: The process of generating a PCBA is more complex ,so it more expensive due to the different components and processes involved in PCB assembly

Packaging: PCBs are usually vacuum packed, whereas PCBAs require compartmentalised or anti-static packaging.

Chapter 1: What is PCB Assembly?

Now that you are already aware of what PCB is, I am going to introduce you to a fundamental process for the PCB.

Have you ever noticed that the boards had got several components firmly attached to them? What do you think they are?

Rigid flex PCB

Many would think they serve for decorations. Absolutely no.

PCB is not capable of independently functioning without those components.

Meaning every single one of them is vital and significant to the functioning of the board.

Technically speaking, detaching any single component would impair the operation of the PCB.

All these elements get embedded through a distinct manufacturing process.

Thus, it is this procedure that we refer to as the PCB assembly abbreviated PCBA process.

BGA Assembly
Therefore, a PCB that has undergone through this course is an assembled PCB.

If you have a close look at the board, then you should see various copper lines.

These are the traces.

They are very tiny yet serve an essential purpose.

Traces link all the components and connectors of the PCB amongst themselves electrically.

They do this by supplying signals throughout these constituents thereby achieving the operation of the board.

Essentially, PCBs serve from simple to complex functions.

Unlike other electronic devices, size doesn’t matter here, in fact, some are tiny and thin, yet they continue to function optimally and run complicated tasks.

So what are the exact areas applications of PCBs?

Chapter 2: PCB Assembly Applications

The PCB applications range from simple devices such as watches, smartphones to sophisticated areas, for example, CT scanners.
Digital watch

To date, the PCBs are in almost all sectors of the economy and industries. It also continues to grow into other unexplored segments.

Now that virtually all electronics have PCBs, it’s easier to pinpoint their uses.

With every development in advancement in technology, PCBs configurations as well improve and become better suited to sustain and tolerate even some of the hostile environment.

The flexibility and configurations of these circuits enable the PCBs to work in various segments and applications.

Remember, at the core of any electronic device is a PCB.

The modern technology significantly utilizes these circuits.

Now, let’s explore some of the typical applications where we got the PCBs incorporated:

1.Industrial applications

In any industry, PCBs play a significant role in running the machines.

The boards run seemingly high-powered machines primarily in the manufacturing or processing factories.

In these areas, the PCBs are fabricated to adapt to and sustain the harsh conditions in which they are getting exposed.
PLC PCB

Such PCB assembly can withstand:

  1. Tremendous multitude vibrations
  2. Corrosive chemicals
  3. Extreme mechanical stress
  4. Fluctuating temperature, etc.

Due to such ever-increasing challenging conditions in the industrial setups, the PCBs technological advancement has been over time propelled to solve the problem.

For that reason very thick copper printed circuit board fits in situations where the average or standard PCBs aren’t favorites.

Note that thick copper PCBs serve a similar purpose to the ordinary ones.

However, the significant difference is that the former one is capable of sustaining a high amount of current output demand together with the battery charge.

Thick copper PCB
Have a look at some of the PCB driven electronics or machinery in this sector.

PCBs are in the: Electric drills, presses, hydraulics, generators especially in the manufacturing and processing industries.
Measuring instruments including Pressure pumps, thermometers, weighing scales, etc.
Power generating equipment such as DC – AC converters, power generators
