Dust-free ovenis a special typeIndustrial oven, mainly suitable for dust-free workshops. According to the needs of the products to be dried, there are 4 dust-free grades to choose from: 100 grades, 1000 grades, 10000 grades, 10000 grades and above. Then, you know the working principle of the dust-free oven is what?
Cleanroom ovens are equipped with HEPA filters to keep the oven cavity free of particles. HEPA filters (High Efficiency Particulate Capture) are now the primary filtration system for electronics and flat panel display clean room assemblies, or any application that requires the reduction or removal of sub-micron particles. HEPA The filter has a deep bed of randomly positioned microglass fibers, where the total bed depth (the thickness of the filter) is very large compared to the average fiber diameter and the effective pores of the free path cross-section.
The channel through which the gas passing through the HEPA filter has to flow is not straight, but very tortuous. As the particles affect the fibers and stick to the fibers, the channels become smaller and the efficiency of the filter increases. Dust free oven These filters are used in special conveying ovens for the LCD industry as well. To protect the filters from overheating in the oven, a special protection system for the filters is implemented. The HEPA filter maintains its efficiency in the oven under normal conditions from one to Years. HEPA does not require any cleaning or maintenance to maintain this efficiency.
semiconductorDust-free ovenThe series are used for pretreatment baking of silicon wafer, gallium arsenide, lithium niobate, glass and other materials in semiconductor manufacturing before gluing, hard film baking after gluing and high temperature baking after development; also suitable for electronic liquid crystal display , LCD, CMOS, IS, pharmaceutical, laboratory and other production and scientific research departments; can also be used for drying, heat treatment, aging and other high temperature tests of non-volatile and non-flammable and explosive items.
