TUOPU THC11 flux is a flux with high solid content (12% solid content) and higher activity. It can be used in foaming, spraying and other forms.
1. Features and advantages
△ Some special activators added to THC11 flux are used to reduce the surface tension between the solder mask and the solder, which greatly reduces the generation of solder balls.
△ The heat-stable activator in the high-solid no-clean flux reduces the incidence of continuous soldering defects in wave soldering and selective soldering.
2. Instructions for use
△ When changing the type of flux, use FD5050 thinner to thoroughly clean the flux container, flux tank, flux spray system, etc.
△ The density and uniformity of the flux coating is a key influence on the successful application of no-clean flux. It is recommended to use a flux coating with a density of 1000 to 2500 micrograms per square inch.
△ Preheating makes the flux on the circuit board dry, enhancing the removal of oxides and the formation of good solder joints. The preheating temperature depends on various factors, such as conveyor speed, types of devices and substrates.
△ When using foam coating, use compressed air with degreasing and dewatering to foam, so that enough flux is maintained on the foam core. Use a pressure regulator to adjust the air pressure to produce uniform bubbles and optimal height.
△ The flux applicator needs to add a thinner to supplement the evaporation loss and maintain the balance of the flux composition.
△ Debris and contaminants will accumulate in the circulating flux coating. For the consistency of the soldering operation, the no longer used flux should be disposed of regularly. After emptying the flux, use the thinner to clean the container and other tasks, and then fill the container with fresh flux. The flux should be allowed to foam and stabilize for a few minutes before the soldering can be resumed.
3.Health and safety
△ The work area should be equipped with a suitable exhaust device to remove the flux. A large amount of inhalation of flux solvents and active agent volatiles that volatilize at soldering temperature can cause headaches, dizziness and nausea. △ The outlet of the wave soldering equipment must be equipped with an exhaust device to completely remove the volatiles.
△ Pay attention to protection during use to avoid prolonged skin contact and direct eye contact with flux. If it touches the eyes, please rinse with plenty of clean water and seek medical attention as soon as possible.
△ THC11 flux contains flammable solvents (flash point is 14 degrees Celsius), and should not be exposed to fire sources or near equipment without fire prevention measures.
