HEPA filters are mainly used to capture particles below 0.5um and various suspended matters. It adopts ultrafine glass fiber paper as filter material, offset paper, aluminum film and other materials as dividing plate, and is glued with aluminum alloy of wooden frame. Each unit has been tested by Nano-flame method, featuring high filtration efficiency, low resistance and large dust capacity.

For the assembly of electronic products, static hazards seriously affect the quality of the product, yield and reliability, must be used for the assembly of electronic products in the purification room for systematic anti-static measures to minimise the degree of static hazards in the production process.

Static electricity in general is 'difficult to see, and not easy to touch', but it is almost everywhere, all the time, so the electrostatic protection is a comprehensive systematic project, in principle, electrostatic protection should be from the control of static electricity generation and control of static dissipation of two aspects, control of static electricity generation is mainly to control the process and the process of process.

The core mission of the Cleanroom, the ‘sterile greenhouse’ of semiconductor manufacturing, is to control airborne contaminant concentrations at the parts per trillion (ppb) or even parts per trillion (ppt) level.
