What is difference between PCB and PCBA
I believe that many people are not unfamiliar with terms related to the electronic industry such as PCB circuit board and SMT assembly. These are often heard in daily life, but many people do not know much about PCBA, and they are often confused with PCB. So what is PCB or PCBA? What is the difference between PCBA and PCB? Let’s take a look at it together.
PCB & PCBA Definition
What is pcb
Many people do not know what is a PCB. PCB (Printed Circuit Board), also known as printed circuit board,often use the English abbreviation PCB (Printed circuit board) or PWB (Printed wire board).This article only introduces the difference between pcb and pcba, and will not introduce too much about how pcb board works.
PCBs are the foundation of modern electronic devices.is an important electronic part, a support body for electronic components, and a carrier for electrical connection of electronic components. Because it is made by electronic printing, it is called a “printed” circuit board”.
The main type of PCBs include:Single layer PCB, Double layer PCB and multi-layer PCB. Other common types of PCBs include flexible PCBs, rigid PCB, and flex-rigid PCBs,Aluminum-based PCB, High Frequency PCB, HDI PCB Board etc.
PCB used in almost every electronic device, ranging from electronic watches and calculators to computers, communication electronic equipment, and military weapon systems, as long as there are electronic components such as integrated circuits, in order to make the electrical interconnection between the various components, use printed circuit boards. If you are a college student or want to know more professional content, you can go to the printed circuit board organization website, these pcb org websites are generally assembled by the most authoritative organizations in the industry,
Below is a picture of the pcb bare board.So what is pcba? What is the difference between pcb and pcba? Next let’s look at the pcba part.
What is PCBA
The full name of PCBA is printed circuit board assembly, which refers to the placement of electronic components on the bare pcb board through PCB SMT assembly technology and PCB DIP assembly technology. The following is the pcb assembly process.
PCBA Process: PCBA=Printed Circuit Board Assembly, that is to say, the PCB empty board is loaded by SMT, and then goes through the entire process of DIP plug-in, referred to as PCBA process.
The core part of all electronic products is composed of PCBA; the realization of all functions is inseparable from PCBA.PCBA is the most important part of all electronic product components, similar to the neural network of the human body. The brain of electronic products: The CPU is mounted on the PCBA. The life, operating speed, reliability and stability of general consumer electronic products have the most direct relationship with PCBA. Therefore, the quality of PCBA is also the most direct determinant of the overall quality of electronic products.If you want to know how much does pcb assembly cost, FS Technology will also tell you without any concealment.
PCBA vs PCB
1.PCB are bare boards,and don’t have components on the boards;
2.PCBA is the electronic components required for welding and assembling on the PCB board through SMT or plug-in processing after the manufacturer gets the PCB as the raw material, such as IC, resistor, capacitor, crystal oscillator, transformer and other electronic components. When the reflow oven is heated at a high temperature, a mechanical connection between the components and the PCB will be formed, thereby forming a PCBA.
From the above introduction, we can know that PCBA generally refers to a processing process, which can also be understood as a finished circuit board, that is, PCBA can only be counted after all the processes on the PCB board are completed. While PCB refers to an bare printed circuit board with no parts on it.
That’s all for the “The difference between pcb and pcba”. If you have more interesting knowledge about pcba, please feel free to contribute to FS Technology PCBA Blog, we can put a follow link for your website.
