The role of air knife in electronic industry:

Nowadays air knife is more and more used in the future industrial development. You will be surprised to find that industrial equipment, especially some cleaning equipment, contains the main components of standard air knives, mainly for drying purposes. Not only can dry but also can improve the production of oil removal and scale blow dry. If you need a clearer understanding of the drying application of air knife in drying equipment, industrial water removal, air knife dryer, degreasing oil removal, beverage bottles, beer bottles, you can consult Leitz super fan Ruitian Mechanical and electrical Technology Co., LTD. In today's air knife evolution as a tool, is an excellent and used in a variety of production applications in industries, such as some electronic industries. Industrial air knife and blower, industrial thermal fan, high pressure fan in the future will also be more applied to equipment in various industries. Now take the electronic industry air knife plays a crucial role.

The role of air knife in electronic industry:

1, first of all, the role of the air knife is to dry the excess scale on the PCB board, to prevent dripping into the preheater in the preheating area, thus causing a fire. The air power of the air knife can be adjusted freely with the size of the object being blown. In this way, it can assist liquid rosin to wet the metal terminal of tin on PCBA, so as to increase the area to be blown dry. In addition, a hot air knife can also be added to the other part of the furnace, which is used for the second wave peak removal of short circuit backup.

2, under normal circumstances, the air blade Angle as far as possible control in 10 degrees or so, because if the air blade Angle adjustment is unreasonable, can cause the PCB surface flux too much or uneven coating, not only in the preheating zone is easy to drop on the heating tube, will seriously affect the service life of heating tube, and can also affect the weld after the PCB surface finish, It is even likely to cause the occurrence of tin defects on some components.

3. Another role of the air knife in the electronic industry is to spray the flux on the foot of the parts in a droplet state and blow it into a uniform layer. That is, in the use of wave furnace, the main function is to use the air knife to blow off the excess flux on the PCB board, so that the flux is evenly coated on the PCB parts surface.

4. The last thing to pay attention to is the installation Angle of the air knife. The air knife should be positioned as far as possible according to the equipment supplier when debugging the machine.
