Recently, air filter design itself has also made significant progress. The most important thing is to remove the partition plate, which is no partition filter development. Pleat filter not only eliminates the risk of damage to the Filter media partition plate, and effectively increases the filtration area and improve filtration efficiency and reduce air resistance, thereby reducing energy consumption.
An example for us to easily understand how to design electronic industry air filters are as followed. Currently the computer we use every day countless drilling dust, but unfortunately not equipped with computer filters, if installed after the computer has enough dust filter. Sticky dust on the integrated circuit may result in open circuit, short circuit, dust directly affect the yield Sullair air compressor accessories products. Today, the demanding semiconductor industry (fab) the cleanliness of the air on the production environment is hard and the air filter is the most demanding requirements.
One measure of chip integration is the width, which is the width of the circuit conductors. In order to calculate the width of micron era, people say manufacturing environment restrictions on dust particle size is smaller than the width of 1/10, with increasingly smaller line width, the saying of 1/10 becomes 1/4 or 1/2. By the year of 2002, ordinary microcomputer P4 processor line width has narrowed to 0.13mm, at this time of any dust may damage the traditional circuit comparison of the particle size and the width is outdated. Fab traditional ventilation form is a big cycle covered the entire ceiling high efficiency Filter plant, the entire surface of the return air grid. Now some chip factory workshop comes with fan filter unit, namely FFU. Two forms of a cycle and FFU can both achieve sufficient cleanliness, but differ in the operation and management and energy consumption.
