SMT chip processing is also a very popular technology in the electronic assembly industry, which can also be said to be a process. Let’s give a detailed answer about the constituent elements of the SMT above.
- Silk screen printing, also known as dispensing. The function of this factor is to stick solder paste or SMT patch on the pad of PCB in order to prepare for the welding of components. The screen printing equipment needed is the screen printing machine, and the SMT production line is at the front.
- Dispensing. Its main function is to fix the components on the flat plate. The required equipment is the dispensing machine, which is located at the front or back of the SMT production line. It can also be a testing equipment.
- Mounting, also called curing. To accurately install the surface assembly parts to the fixed position of PCB, the equipment required in this step is the mounter. This product is located behind the SMT production line.
- Reflow soldering. The effect is to melt the solder paste so that the components assembled on its surface can be bonded with the PCB board. The required reflow furnace is located behind the mounter.
5. Clean the SMT. Firstly, the welding slag harmful to human body on the assembled welding board needs to be cleaned. The cleaning machine used is this kind of equipment, and the position does not need to be fixed.
