Best SMT PCB Assembly Manufacturer – PCBFuture

What is SMT PCB assembly?

SMT PCB assembly is a method in which the electrical components are mounted directly onto the surface of a printed circuit board. It allows components to be mounted directly on the surface mount PCB. This technology helps to miniaturize components.

Surface mount technology is actually the most commonly used process. Therefore, its application is very wide. As surface mount technology encapsulates more and more electronic components in a small space, most devices today use surface mount technology. So as miniaturization becomes more and more important, the importance of SMT technology is self-evident.

PCBFuture has more than 10 years of experience in SMT PCB assembly. Through an automated SMT assembly process, our circuit boards can ensure the best performance in the most challenging applications.

What's the process for SMT PCB Assembly?

The process of using SMT to manufacture PCB devices includes the use of automated machines to assemble electronic components. This machine places these elements on the circuit board, but before that, the PCB file must be checked to confirm that they have no problems affecting the manufacturability and functionality of the device. After confirming that everything is perfect, the process of SMT PCB assembly is not limited to soldering and placing elements or compounds on the PCB. The following production process must also be followed.

1. Apply solder paste

The initial step when assembling the SMT PCB board is applying the soldering paste. The paste can be applied to the PCB via silk screen technology. It can also be applied using PCB stencil tailored from a similar CAD output file. You only need to cut the stencils using a laser and apply the soldering paste to the parts where you will solder the components. The solder paste application must be carried out in a cool environment. Once you are done applying, you can wait for some time for assembly.

2. Inspection of your solder paste

After the solder paste is applied to the board, the next step is to always check it through solder paste inspection techniques. This process is critical, especially when analyzing the location of solder paste, the amount of solder paste used, and other basic aspects.

3. Process confirmation

Just in case your PCB board is utilizing SMT components on either side, there will be a need to consider repeating the same process for secondary side confirmation. you will be able to track the ideal time to expose the solder paste to room temperature in here. This is when your circuit board is ready to be assembled. The components will still be ready for the next factory.

4. Assembly kits

This basically deals with the BOM (Bill of Materials) used by CM for data analysis. This facilitates the development of BOM assembly kits.

5. Stocking kits with elements

Use the barcode to pull it out of stock and include it in the assembly kit. When the components are fully installed in the kit, they are taken to a pick and place machine called surface mount technology.

6. Preparation of components for placement

A pick-and-place tool is employed here to hold every element for assembly. The machine also uses a cartridge that comes with a unique key that corresponds to the BOM assembly kit. The machine is designed to tell the part that the cartridge hold.

What's the SMT PCB assembly can provide?

SMT printed circuit boards have a wide range of advantages. The most important of the advantages for SMT is small size and light weight. In addition, some other advantages of SMT include:

1. Quick production: circuit boards can be assembled without drilling, which means production is much faster.

2. Higher circuit speeds: in fact, this is one of the main reasons why SMT has become the technology of choice today.

3. Assembly automation: it can realize automation and its many advantages.

4. Cost: The cost of small components is usually lower than that of through-hole components.

5. Density: They allow more components to be placed on both sides of the SMT printed circuit board.

6. Design flexibility: through hole and SMT component manufacturing can be combined to provide greater functionality.

7. Improved performance: SMT connections are more reliable, so the board can improve performance.
