Nowadays, the semiconductor industry (chip factory) has very strict requirements for air cleanliness in the production environment, and the requirements for filters are also relatively stringent. Because dust stuck to integrated circuits may cause open circuits and short circuits, the dust directly affects the product yield. High-efficiency PTFE composite filter material can be used to achieve high filtration efficiency.
“Line width” is one of the indicators for measuring chip integration, that is, the width of the wires on the circuit. In the era when line width was calculated in microns, people said that the limit on dust particle size in the manufacturing environment was less than one-tenth of the line width. As the line width continued to become smaller, the saying 1/10 became 1/4, 1/2. In 2002, the line width of the P4 processor in ordinary microcomputers was reduced to 0.13μm. At this time, any dust may damage the circuit.
The traditional ventilation form of chip factories is “large circulation”. The entire ceiling of the workshop is covered with high-efficiency filters, and the entire floor is a return air grid. Many chip factories now use filter units with their own fans, namely FFU. Sea salt particles in the air are the enemy of all electronic industries, but the particles of sea salt dust in the air are relatively large and can be filtered out by ordinary filters.
FFU is suitable for obtaining high-level clean environments in various environments. It provides high-quality clean air for clean rooms and micro-environments of different sizes and cleanliness levels. In the renovation and renovation of new clean rooms and clean factory buildings, the cleanliness level can be improved, noise and vibration can be reduced, and the cost can be greatly reduced. It is easy to install and maintain, making it an ideal component for clean environments.
FFU air purifier uses industry-leading, high-quality HEPA filters. In addition, some people will pay special attention to the level of the filter, thinking that the higher the level of the filter, the better. In fact, the higher the level of the filter, the stronger the sealing, and the worse the air penetration. Although the filtered air is good, the unit The amount of clean air provided during the period is less, and the air adjustment effect of the entire room is not good. We recommend that H12 or above filters are sufficient. It is recommended not to use H14, especially U15 or above filters.
The currently independently developed high-efficiency PTFE composite filter material is the core filter material of the ultra-high-efficiency filter of the FFU fan filter unit, with H13- U16-level reliable filtration grade, low wind resistance and low energy consumption. High-efficiency PTFE composite filter material can meet the filtration efficiency grade requirements of sub-high-efficiency, high-efficiency and ultra-high-efficiency air filters, and is highly recognized by customers.
