With the continuous development of electronic technology, PCB (Printed Circuit Board), as the core component of electronic products, is also constantly innovating in its manufacturing and assembly technology. Traditional THT (Through-Hole Technology) PCB assembly technology, as a long-standing assembly method, has always played an important role. However, with the development and popularization of SMT (Surface Mount Technology), THT PCB assembly technology is also constantly evolving and improving to meet the increasing demands for performance and reliability of modern electronic products.

THT PCB assembly technology is still widely used in many fields due to its stable and reliable characteristics, especially in situations where the stability of electronic products is required. In contrast, although SMT technology has certain advantages in miniaturization, high density, and high speed, THT technology still occupies an irreplaceable position in some specific application scenarios. For example, in high-temperature, high-pressure, and high-vibration environments, THT assembly connections are stronger and more stable, and can better adapt to working requirements in extreme environments.

As the functions of electronic products continue to be enriched and diversified, THT PCB assembly technology is also constantly evolving and improving to adapt to new needs and challenges. Based on traditional THT technology, new THT PCB assembly technologies continue to emerge, providing more possibilities for the design and manufacturing of electronic products.

1. Innovative material application: Traditional THT PCB assembly technology mainly uses solder as the connection material. However, with the improvement of environmental awareness and the increasing requirements for the reliability of electronic products, new soldering materials such as lead-free solder, high-temperature environmental protection Solder, etc. are also gradually used in THT PCB assembly to improve connection quality and reliability.

2. Application of automation equipment: In order to improve production efficiency and reduce labor costs, more and more automation equipment is used in THT PCB assembly production lines. The introduction of automatic plug-in, automatic welding and other equipment not only improves production efficiency, but also improves assembly quality and consistency.

3. Refined process control: The process control of THT PCB assembly technology is also constantly refined and optimized. Through advanced process control technology, parameters such as welding temperature and welding time can be more accurately controlled to ensure welding quality and stability.

4. Structural optimization design: In order to adapt to the continuous shrinkage of electronic products and the continuous improvement of performance, THT PCB assembly technology is also constantly optimizing the design. By improving the structure and layout of connectors and optimizing PCB board design, the demand for miniaturization and lightweight of electronic products can be better met.

To sum up, THT PCB assembly technology, as a traditional assembly method, still plays an important role in the manufacturing of electronic products. With the continuous advancement and innovation of technology, new THT PCB assembly technologies continue to emerge, providing more possibilities and choices for the design and manufacturing of electronic products. It is believed that in future development, THT PCB assembly technology will continue to play an important role and become one of the important assembly methods for electronic product manufacturing.
