SMT has high assembly density, small size and light weight of electronic products. The volume and weight of the nozzle components of the placement machine are only about one-tenth of the traditional plug-in components. Generally, after the SMT process is adopted, the electronic products are reduced in size and weight.
Advantages of SMT soldering
1. Flexibility and agility .SMT can easily produce various physical shapes during soldering, which can be realized in different applications.
2. Compatibility. Compared with other component soldering technologies, SMT soldering is more compatible. For example, soft solder alloy technology is more suitable for electronic components, such as integrated circuits, components, precision electronic devices, etc. The internal structure of PCB must also be designed according to this tolerance range.
3. Practicality. In the production process, SMT soldering has relatively low environmental requirements, unlike solder alloys, which must have a stable environment to operate. As long as it matches the usage environment, you can operate SMT soldering and complete the job.
4. Performance. SMT soldering has better performance and more convenient production, so it is very popular among enterprises.
5. Cost and competitiveness. The process based on SMT soldering is very easy to synchronize with intelligent production and automation, which not only greatly saves labor, but also facilitates future electronic manufacturing and saves costs for enterprises. In general, the five advantages provided by SMT soldering have a very important impact on future electronic products. It not only greatly improves work efficiency, but also saves labor costs.
Matters needing attention when operating SMT soldering
1. The quality and tensile strength of SMT soldering.
2, The working temperature of SMT soldering. Under normal circumstances, the preheating rate of SMT soldering is 1.3~1.5 degrees/s, and the temperature will rise to 150 degrees within 90~100s;
The temperature in the holding area is about 150-180 degrees, and the time is between 40-60 seconds; the temperature in the reflow area is from 180 degrees to a maximum of 250 degrees, and the time is 10-15 seconds. It takes 10-15 seconds to return to the holding area. 30 seconds for quick cooling.
3. Before using SMT soldering technology, the compatibility of SMB should be considered first, especially the humidity and heat resistance of the pad, and special attention should be paid. As a surface mount technology, SMT soldering has received great attention, and it has also brought great convenience to the development of the industry.
Nowadays, SMT soldering has become the need of the development trend of the times, and it is also one of the soldering technologies that electronic product manufacturers must use. Here, remind the major demand enterprises, be sure to choose high-quality soldering tools, do not just look at the price and ignore the quality, so as not to lose more. We recommend the use of soldering tools for electronic products: JBC AiXun Weller... these big brands, they are not only smart but also more secure to use.
