What does PCB assembly mean?

 PCB assembly refers to the process of soldering Electronic Components and Cable Connectors I/O Connectors on the PCB to form a PCBA. Usually use professional production machinery, mass production, PCBA Manufacturing process is usually called PCBA production.
What is PCB assembly.

Circuit board components participate in various steps. This is a non-linear process, indicating that factors need to be considered, and the process can be changed and adjusted based on these factors. The expected results and the use of PCBA are one of the main considerations that determine the components and general circuit board assembly process.
The following are some parts and components PCB assembly that needs to be carried out:
1. Basic printed circuit board or substrate
2. Electronic Components to be installed on the circuit board. This depends on the use of the circuit board and the complexity of the equipment.
3. Soldering materials, solder wire, solder paste, preforms and other welding materials. The preform depends on the type of welding to be carried out.
4. Flux
5. Other welding equipment such as soldering station, wave soldering machine, inspection, test equipment and SMT equipment. The use of equipment depends on the expected results, cost and time resources.
When all the necessary component materials are prepared, the assembly process can begin. But before we get into the assembly process (it is a different type), let us know more about the circuit board itself.
Method of mounting circuit board components
The technology used to assemble the circuit board and its various components is called the mounting technology board assembly in the circuit. Depending on the application, cost, scale and other considerations, manufacturers use different kinds of installation methods. Here are some of the most commonly used techniques:
Surface mount components
SMT chip processing (or surface mount technology, also known as SMT) is a method in which Electronic Components standing upright on the PCB are directly glued to the surface of the circuit board. The final circuit board is called a surface mount device (SMD). This The technology was originally called "flat mounting".
Most electronic boards currently produced are manufactured using SMT. Because of its increased circuit density and ability to produce results on smaller circuit boards, it has replaced the more traditional through-hole technology (more on the next point). Generally, SMT uses solder to connect the components to the circuit board, but in some cases, adhesive spots can also be used on the second side to keep the components in the reflow oven.
Through-Hole Assembly
Through-hole technology (also called "through-hole") is a mounting technology in which Electronic Components are inserted through holes built into the circuit board and then soldered to the pads. Welding can be done manually or using DIP plug-in processing.
Through hole technology replaces the traditional point-to-point structure. As double-sided and multi-layer boards become more and more popular, through holes are becoming popular. It is used to connect the component and the conductive layer to ensure the normal operation of the circuit board. These components are equipped with leads to connect to the other side of the through-hole board.
In contrast to the SMT method, the through-hole technology provides greater cohesion for the circuit board assembly because the unit is placed through the circuit board itself.
Electromechanical assembly
Electro-Mechanical components use electrical and mechanical units to cover a wide range of functions. Since electromechanical components are usually used in applications with complex wiring and components, components need to be put together manually.
Therefore, it can usually be time-consuming. Use this technique and break down the process into individual market segments and use experts in each segment. This way we can shorten the lead time.
