Under normal circumstances, the inclination angle of the integrated air knife of the Reitz high-pressure fan should be about 10 degrees; if the angle adjustment of the "air knife" is unreasonable, it will cause too much flux on the surface of the PCB, or uneven coating, not only in the preheating zone. When it is easy to drip on the heating pipe, the tilt angle of the integrated air knife of the high pressure blower of the Reitz should be about 10 degrees; if the angle adjustment of the "air knife" is unreasonable, the surface of the PCB will be excessively fluxed or unevenly coated. Not only when it passes through the preheating zone, it is easy to drip on the heating pipe, which affects the life of the heating pipe, and it will affect the surface finish of the PCB after soldering, and may even cause the poor tinning of some components.

Another function of the Reitz high-pressure blower is to spray a flux onto the part's feet and blow it into a uniform layer. Simply put, in the use of the wave furnace, the main function of the "air knife" in the high-pressure fan is to blow off the excess flux on the PCB surface and evenly spread the flux on the PCB part surface.
The blowing function of the Reitz high-pressure fan is widely used in the circuit board industry, especially after integration with the Reitz air knife. The members of Dongguan Ruitian Electromechanical "target=_blank> electromechanical R&D and sales team are all engaged in the fan industry for many years, and their professional level is obvious in the industry.
Dongguan Ruitian Electromechanical "target=_blank> Electromechanical Technology Co., Ltd. has accumulated some experience in the process of researching wind turbines for many years, here to share the role of the high pressure blower in the circuit board industry.
Simply put, the role of the Reitz high-pressure blower is to blow off excess rosin on the PCB to prevent dripping into the preheater in the preheating zone and causing a fire. The size of the wind that integrates the air knife with the high pressure fan can be adjusted freely with the size of the rosin. Auxiliary liquid rosin wets the metal terminal on the PCB to be tinned. Increases the wetted area. In addition, some furnaces have a hot air knife, which is used to remove the short circuit from the second peak.
It should be noted that the angle of the integrated air knife installation of the Reitz high-pressure fan can be requested by our technicians when positioning the machine. Do not arbitrarily change the maintenance or maintenance during use.
