[Circular Air Knife]
Nowadays, air knives are increasingly used in the development of future industrial fields. You will be surprised to find that industrial equipment, especially some cleaning equipment, include standard air knives as the main component, mainly for dry purposes. Not only can it be dried, but it can also improve production, remove oil and scale and blow dry. If you need a clearer understanding of the application of air knives in drying equipment, industrial water removal, air knife dryers, degreasing and oil removal, and drying of beverage bottles and beer bottles. Nowadays, the wind knife has evolved as a tool and is an excellent industry that is used in various production applications, such as some electronic industries. Industrial air knives and blowers, industrial hot air blowers, and high-pressure blowers will definitely be used more in equipment in various professions in the future. As far as the electronics profession is concerned, the wind knife plays a vital role.

The effect of air knife in the electronic industry:
1. The main function of air knife is to dry the remaining scale on the PCB board to prevent it from dripping onto the preheater in the preheating area and causing a fire. The wind force of the wind knife can be freely adjusted according to the size of the object being blown. In this way, the liquid rosin can help wet the metal terminals that need to be tinned on the PCBA, thereby increasing the drying area. In addition, some furnaces can also add a hot air knife, which is used to remove short circuit backup at the second wave peak.

2. Another function of the air knife in the electronics industry is to blow the flux sprayed on the feet of the parts into a uniform layer. That is to say, in the use of wave furnace, the primary effect is to use an air knife to blow away the remaining flux on the PCB board surface, so that the flux can be evenly coated on the PCB part surface.

3. Under normal circumstances, the skew angle of the air knife should be controlled at about 10 degrees as much as possible, because if the angle of the air knife is adjusted unreasonably, it will cause excessive flux or uneven coating on the PCB surface, not only when passing through the preheating zone. It is easy to drip on the heating pipe, which will seriously affect the life of the heating pipe, and will also affect the surface finish of the PCB after soldering, and may even cause poor tinning of some components.

The last thing to pay attention to is the angle of the air knife device. The air knife should be positioned according to the equipment supplier when debugging the machine. Do not change it at will during maintenance. If there are any changes, you need to communicate with professional technicians. , so as to ensure that the blown items achieve the best effect as much as possible.
