Electronic factory editor explains SMT processing and welding

As we all know, welding is an important process in the SMT processing, and the welding process is just like a dazzling pearl in the bright SMT processing. Therefore, it is necessary to deeply understand the professional SMT processing and master its welding process. The welding process flow of SMT processing patch can be divided into three types. Next, we will introduce them one by one.

What is the welding process for SMT processing?

Firstly, the wave soldering process of SMT processing is introduced. How can this process be completed? The electronic components are firmly fixed on the printed circuit board by using SMT steel mesh and adhesive, and then the key means - wave soldering equipment is used to solder the circuit board patch immersed in molten tin. What is the purpose and significance of doing these jobs? This is the role of this process? Through such a process, the volume of electronic technology products can be reduced, which greatly conforms to the development trend of today's electronic technology products.

The reflow welding process of chip processing is mentioned again. SMT steel mesh is also used, but solder paste is leaked onto the electrode pad of components through this steel mesh. Then, a reflow machine is used to re melt the solder paste on it, so as to soak the components and circuits on the patch and allow them to solidify. Because this process is simple and fast, it can be imagined that it has become a very common welding process in SMT processing.

To elaborate is the laser reflow welding process of chip processing. This process is basically the same as the second process, except that the tools used are different. Here, the laser beam is used for a series of operations. The advantages of this process are incomparable with the previous one, and it is faster and faster.

The understanding of several important welding processes that SMT processing technology should have is conducive to making use of its choices in the daily use process, so that SMT processing technology can be done like a fish in water and better play the role of SMT processing.

PCB manufacturers, PCB designers and PCBA manufacturers will introduce SMT processing and welding processes.
