When it comes to electronics, there are lots of terms and acronyms that can make it hard to understand which parts mean what. If you have wondered what the difference between PCBA and PCB is, then read on to understand how they differ and what purposes they serve. PCB is the Printed Circuit Board, and PCBA is the Printed Circuit Board Assembly. While these two terms sound similar in nature and are referred to interchangeably, they are actually quite different.
Let’s get to the crux of what a PCBA and PCB do, respectively.
The role and definition of a PCBA
The PCBA is a board that holds all the critical electronic components required for the board to function. It is a complete and functional board, so it does not need the other parts. A PCBA supports and connects electrical parts, using tracks, pads and other features which are etched from layers of copper. A PCBA is essential and made up of a combination of PCBs with the components assembled.
The role and definition of a PCB
The role of a PCB is to provide an electric connection and support to the existing electrical components of a circuit. A PCB is often visually identified as a green board and is commonly found in electronic devices. If you have ever pulled apart a device, you might have recognised that green board and all the metallic marketing and labels.
There are 3 types of PCBs
All PCBs are not made equal, and while the intricate designs and requirements may vary significantly, they can be broken into three different categories. These three types can be identified as follows:
- Single-sided PCBs
- Double-sided PCBs
- Multilayer PCBs
The single-sided PCB is exactly how it sounds, there is one side that has the conductive copper and components mounted on one side. The double-sided PCBs will have both sides of the board mounted with circuit traces. The multilayer PCB has more than two layers, which is different to a double-sided board. If you are unsure whether you require the single, double or multilayer PCB, you can communicate with an industry expert like Venture Electronics to best understand your needs.
What kind of industries utilise PCBs and PCBA’s?
Venture Electronics service a number of businesses and a number of industries, as all professional environments require multifaceted electronics. Here are some of the industries that require PCBs.
Depending on the industrial use, industrial PCBs can be used for power supply units, electronic switch gears, energy control systems, electronic smart labels, robotics, industrial drives and inverters. The use of PCBs and PCBA’s are critical to the operation and innovation of countless businesses in Oceania.
The medical industry relies on a number of electronics to safely administer care to patients, and monitor the treatment going forward. There are also many drugs, human tissue and other important medical products that require appropriate storage in a medical setting.
These medical PCB electronics are used for blood glucose meters, drug delivery systems, medical wearable devices, imaging, hand-held wireless controllers, hearing aids, and so much more.
Businesses operating in the telecommunications industry have long been at the forefront of innovative electronics, and continue to utilise PCBA and telecommunications PCB electronics. Some of these electronics include broadband equipment, mobile transmission electronics, information security technology and mobile networks.
