At present, the function of FFU dust-free workshop purification membrane is to control the cleanliness and temperature and humidity of the atmosphere that products come into contact with, so that products can be produced and manufactured in a good environment.
The SMT workshop has clear requirements for temperature and humidity. First of all, it is mainly for the solder paste to work in a better environment. The temperature will affect the activity of the solder paste and the activity of the related solvents added to the flux. certain influence.
High temperature will increase its activity, ultimately affecting the effects of screen printing, mounting and reflow.
It is easy to have weak soldering and dull solder joints.
The amount of humidity will cause the solder paste to absorb water vapor in the air. If it absorbs too much water vapor, it will cause air voids, flying chips, continuous soldering and other phenomena during reflow.
FFU dust-free workshop purification membrane is suitable for various clean rooms from level 1 to 100,000. It adopts a special processing technology and is a microporous film made by calendering, extrusion, biaxial stretching and other methods.
This kind of membrane has excellent breathability, corrosion resistance, aging resistance, high temperature resistance and other properties.
According to the usage requirements, the pore diameter can be between 0.1-10um, the thickness can be between 2-100um, the porosity can reach 50%–80%, and there are up to hundreds of millions of micropores per square centimeter.
The FFU dust-free workshop purification membrane produced by the manufacturer uses imported raw materials, has a full set of advanced production equipment, an advanced clean room and an independent composite slitting workshop to ensure the production quality of ptfe membrane; Production and testing instruments imported from the United States are used to test the quality of the PTFE film, and it has passed international SGS testing and certification, as well as ISI testing and certification.
