What is pcba?
In the electronics field, a PCB serves as a carrier for electronic components and provides a platform for electrical connections between them. In other words, a bare PCB is not functional on its own and requires the addition of components.
With the popularization of electronic technology, people have a better understanding of printed circuit boards, but there may be some conceptual deviations. Many users tend to call the green circuit board in a computer or other device a "PCB," which is actually an inaccurate term. In fact, as consumers, the circuit boards we commonly see are already assembled and are called PCBA boards, known as the "mother of electronic products," and are an indispensable part of modern electrical engineering. This article will provide a detailed introduction to the concept of PCBA, although terminology may vary in different regions.
What does PCBA mean?
In fact, PCBA is the abbreviation for Printed Circuit Board Assembly, a term commonly used in Southeast Asian countries but less formal in European and American countries.
In the electronics field, the PCB is the carrier of electronic components and the platform for electrical connections between components. In other words, the bare PCB itself cannot function and needs to be combined with components.
Therefore, PCBA represents the process of placing components on the surface of a PCB using assembly technologies such as SMT and THT, and then fixing them through high-temperature soldering.
The final PCBA board is used for electronic products and is the final form of the electronic products we see.
How does the PCBA process work?
After understanding what PCBA is, let's take a look at its process!
Before performing PCBA, it is necessary to ensure that some basic materials and equipment are prepared: components, bare boards, soldering materials, soldering irons, and some commonly used tools.
A key step in PCBA is design, including wiring, drilling, component types, and placement. Send the design files to the manufacturer for PCB production. After receiving the PCB, accurately install the components in the designated positions according to the design. Apply an appropriate amount of solder to the component pins and solidify the solder with a soldering iron to ensure good electrical connection.
Once, a hobbyist made a detailed video showing the entire process from PCB design to the final PCBA. Unfortunately, I lost the link, but I will share it if I find it later.
Commercial use:
In terms of equipment, we need to prepare, including but not limited to: pick-and-place machines, welding equipment, testing equipment, workbenches, etc.
The simplified PCB assembly process includes: loading → conveying → solder paste printing → SPI → component mounting → reflow soldering → AOI → inserting through-holes → wave soldering → AOI → cleaning → final inspection.
The entire process is carried out in an automated factory, and any error in the process will render the PCBA board unusable.
The significance of PCBA
Before the 20th century, electronic components were connected by wires, which led to a series of problems:
Complex manufacturing processes
Disordered internal structure
Difficult maintenance and repair
The emergence of PCBA boards simplified the connection method of components, making the connections inside the equipment orderly, and ultimately accelerating the development of electronic technology. It took only 20 years for PCBA boards to be born and completely replace traditional connection methods, and their significance is self-evident.
With continuous technological advancements, more complex technologies are needed to meet manufacturing needs, and the development of PCBA remains at the forefront of the times. From rigid to flexible, from 10 layers to 100 layers, from THT to SMT, PCBA technology continues to develop. Modern electronic products are getting smaller and smaller, while their functions are becoming more and more powerful.
In addition to having a positive impact on devices, the development of PCBA has also driven the transformation of the entire electronics industry. Traditional integrated manufacturing and trading companies have become a thing of the past, and more and more companies are separating sales and production. Most PCBA manufacturing is outsourced to professional manufacturers. This seemingly insignificant change has greatly promoted the development of the electronics industry. Sales companies can focus on their strengths in sales and marketing, while PCBA companies focus on research and technology investment. Ultimately, the quality of electronic products has been improved, and their functions have become more powerful.
