Name:Kuril series of environment-friendly Disposable Flux
Category:Chemical water
 
Detail:
I. Overview:
QD-900 series for the pale yellow liquid - red-brown rosin Disposable extinction of flux, the products are in strict accordance with U.S. military standards (MIL-F-14256), and the United States federal standards (QQS-571E, BS-5625) The regulatory requirements to operate.

Second, product characteristics:
In the modern large-scale electronic integrated circuits spot more intensive production continuously improve the situation, our engineering staff in long-term view of the PCB board after welding spot is complete, the solder joint refraction to stimulate reflection, it is easy to cause eyestrain Has significantly affected the efficiency of our work. The company works with extinction agent and synthetic alkyd-based system to do the QD-900 (A, B, C) series of liquid rosin-free cleaning of extinction after the PCB solder flux in the solder joint boards were formed to protect white film, even if In the intensity of light will not stimulate the eyes, welding after PCB surface residue formation, uniform, fast-drying, non-stick in hand, rosin residual thin transparent, greatly facilitate the work of the sequence after the treatment, is now widely used in TV Main Board and the PCB-car audio plug-welding. This series of products applicable to spray foam, hand Baptist welding equipment, such as foam, hand-welding the Baptist way of solution to maintain this proportion in this constantly exposed to the agent continued to absorb water vapor in the air under the influence of each proposal Zhou cleansing foam hand with the trough of the Baptist furnace, new agents. Solder temperature: 235 ℃ -250 ℃, the 5-8 second-rate, preheat solder-80 ℃ -100 ℃.
