Development prospect of selective wave welding

With the continuous progress of modern science, the development of science and technology has greatly promoted the rapid development of various fields. In the field of wave soldering, due to the rapid penetration of selective wave soldering, great changes have taken place in the technical structure, product mechanism, function and composition and production mode of welding. This paper briefly describes the current situation of selective wave soldering technology, and then analyzes and discusses the application and development trend of selective wave soldering technology in high-end electronic products.

1, the application of selective wave soldering technology - want to weld there welding there!!

At present, the selection of wave soldering has nitrogen - filled protection. Nitrogen is an inert gas, which can improve the occlusal ability of components and printed boards, reduce the degree of oxidation, and speed up the welding reaction. Using nitrogen - filled welding, the main body in the following two aspects.

1.1 reduce the oxidation of solder and increase the utilization rate of solder.

2.2 welding quality of welding points

2. Development trend of selective wave soldering technology

2.1 flexible welding method

Selective wave soldering can be single point welding, or more point drag welding. It can heat the welding pin according to the requirements, without affecting the surrounding components.

2.2 simple operation

Quick programming and easy maintenance.

2.3 different from traditional wave soldering, selective wave soldering can protect surface-mount components to weld through hole components, greatly reduce the production process and cycle time, and improve the welding quality of PCB. Selective wave soldering allows the full and effective use of SMT mount equipment to eliminate the use of dispensing machines. It is believed that selective wave soldering will be more widely used in electronic assembly and become a competitive welding technique.
