Halogen free and no clean flux 881 Application

➤ The density and uniformity of the flux coating have a critical impact on its successful application. The spray method can best exert the effect of no cleaning flux.

➤ Heming 881 lead-free soldering flux is suitable for lead-free alloy solders such as Sn-Ag-Cu and Sn-Cu.

➤ Use compressed air spray that is degreased, dewatered and cooled. Non operational states should avoid contact between flux and air as much as possible to avoid reducing the service life of flux. When it is found that the flux has become turbid or suspended, the flux in the groove should be removed in a timely manner, the flux container should be cleaned, and the flux should be replaced.

➤ When using peak equipment, it is recommended to preheat at 110 ± 10 ℃ to facilitate pre activation of the flux and improve the welding effect.

➤ During spray operation, pay attention to the adjustment of the nozzle, and make sure that the flux is evenly distributed on the PCB surface.
