Shenzhen SMT patch quality development history





The development of SMT in Shenzhen conforms to the trend of SMT industry, and it is a trend to develop SMT technology in China. Although the trend is obvious, we will also find the problems in it. The most noticeable one is the quality of the patch. The quality of the patch is the most obvious problem in China.



The development and progress of SMT technology are mainly in four directions.First, it ADAPTS to the assembly requirements of new surface assembly components;The second is to adapt to the development of new assembly materials;Third, the variety of modern electronic products, update the characteristics of rapid adaptation;The fourth is to meet the assembly requirements of new assembly forms such as high-density assembly, three-dimensional assembly and mems assembly.

Mainly reflected in:

1. With the fine-spacing of component pins, the micro-assembly technology of 0.3mm pin spacing has become mature and is developing towards improving the assembly quality and the pass rate of primary assembly;

2. With the popularity of the ball-shaped pin form of array at the bottom of the device, the corresponding assembly technology and testing, repair technology has become mature, and is still in the process of continuous improvement;

3. In order to adapt to the development of green assembly and the assembly process requirements of new assembly materials such as lead-free welding after they are put into use, relevant process technology research is under way;

4. In order to meet the assembly requirements of multiple varieties, small batch production and rapid product update, the assembly process rapid recombination technology, assembly process optimization technology, assembly design and manufacturing integration technology are constantly proposed and under study;

5. In order to adapt to high-density assembly and three-dimensional assembly, the assembly technology is the main content to be studied in the future;

6. It is necessary to strictly install the surface assembly technology required by special assembly such as azimuth and precision, and it is also the content to be studied in the future, such as surface assembly of electromechanical system.

Shenzhen SMT patch development to conform to the trend of change that must take quality into account, after all, quality is the subject of customer concern.
