The demand for smaller, faster, and more efficient electronic devices is rising and this has led to the development of intricate circuit boards, commonly known as printed circuit boards (PCBs). However, you may be confused about how PCB and PCBA differ.
In this article, we’ll look at the differences between PCB and PCBA, and how they matter in the manufacturing process. Let’s dive in!
What is a PCB?
PCB, or printed circuit board, is a flat board made of non-conductive material (usually fiberglass) with conductive pathways printed onto it, connecting various electronic components.
It serves as the backbone of any electronic device and provides a platform for components to be attached to create a pathway for the flow of electricity.
PCBs come in different types – single-sided, double-sided, and multi-layered – depending on the complexity of the device they are used in. They are also available in various shapes and sizes, which cater to the specific needs of the device they will be used in.
What is PCBA?
A PCBA is a complete module that includes both the PCB and all the necessary components required for the device to function. It is an important step in the manufacturing process, as it transforms a bare PCB into a functional electronic device.
The PCBA process begins with the solder paste being applied to the pads on the PCB. The electronic components, such as resistors, capacitors, and integrated circuits, are then placed on the solder paste according to the design specifications.
The PCBA is then tested to make sure all the parts are working correctly.
5 Differences between PCB and PCBA
- Functionality:
The primary difference between PCB and PCBA is their functionality. A PCB serves as a platform for components to be attached, while a PCBA is the final product that can perform a specific function. - Complexity:
PCBs are relatively simple compared to PCBAs. A PCB consists of only the conductive pathways, while a PCBA includes a variety of electronic components attached to the PCB. The complexity of a PCBA depends on the complexity of the device it is used in. - Manufacturing Process:
As mentioned earlier, the manufacturing process for PCBs and PCBAs is different. PCBs are mainly created by etching copper traces onto a non-conductive material, whereas PCBAs require the additional step of attaching electronic components to the PCB. - Cost:
Due to the additional components and manufacturing process, PCBAs tend to be more expensive than PCBs. However, this cost is justified as it results in a fully functional electronic device. - Testing:
As PCBAs are the final product, they undergo rigorous testing to ensure they function correctly. PCBs, on the other hand, may undergo some testing, but the primary focus is on the functionality of the components attached to them.
