Why You Should Choose the Best SMT PCB Assembly Manufacturers

Surface mount PCB assembly has helped electronic manufacturers to design modern devices. The surface mount PCB assembly is a type of mounting technique. Its process involves the use of an automated machine to pick and place components on a circuit board. Also, SMT assembly plays a significant role in the miniaturization of electronic devices.

This highly automated assembly process is highly preferred among PCB manufacturers due to the benefits it offers. There are several manufacturers that specialize in SMT assembly.

What is Surface Mount PCB Assembly?

SMT PCB assembly is simply a process that involves the mounting of electronic components on a PCB surface. Surface mount technology (SMT) has helped to achieve the miniaturization of electronic devices. This process is a highly automated one that enables manufacturers to fabricate different types of circuit boards within a short time. Also, the use of the automated pick and place machine contributes to the speed of this process.

There are many advantages of integrating surface mount technology in PCB assembly. One of the most crucial benefits of SMT assembly is that it enables the production of smaller products. Also, SMT printed circuit boards are easier and faster to assemble compared to through-hole technology.

The automated SMT assembly process involves the use pick and place machine to mount components directly on a PCB surface.  Also, surface mount technology is a common assembly method integrated by most PCB manufacturers. Surface mount assembly plays a vital role in the production of modern electronic devices. The integration of SMT helps to support BGA component assembly.

Steps Involved in SMT PCB Assembly Process

Solder paste application

The application of solder paste on the bare PCB is the first step in this process. Here, the PCB assembler will add solder paste to some areas in the board that need soldering. The solder paste is a mixture of solder and flux. Also, the flux makes soldering possible. In this step, the assembler will place a solder screen on the PCB and squeezes solder paste via the holes. A runner squeezes a good amount of solder paste via the hole.

Component placement

This step involves careful placement of components on the circuit. Also,  these components are carefully picked and placed on the circuit board with the help of an automated machine. Also, this machine utilizes gripper nozzle or vacuum to pick the components and then place them on the circuit board. Printed circuit board comprises a wide range of different SMT components. The diodes and transistors are usually in small packages while ICs are in different kinds of packages.

Reflow soldering

Even though solder paste holds the electronic components, these components are not completely attached to the PCB. Therefore, there are no electrical connections yet. The printed circuit board needs to undergo reflow soldering. Also, the circuit board passes through a reflow oven and heats up till the solder paste gets to an extreme temperature enough to form the solder joints.

Assemblers need to control this process to avoid too much temperature. After the circuit board has passed through the oven, it passes through coolers. This helps to solidify the molten solder. In addition, this creates a solder joint that connects the components to the PCB.

Inspection

Quality assurance is crucial in SMT assembly. This step involves evaluating the printed circuit boards to detect any defect.
