The chip package mainly has the following four functions: fixed pin system, physical protection, environmental protection and enhanced heat dissipation. The other role of packaging is to protect the chip from the environment. It can protect the chip from moisture and other gases that may interfere with the normal function of the chip, which will adversely affect its normal operation. The curing of the epoxy resin conductive adhesive for semiconductor packaging requires a clean oven , and a nitrogen filling system is configured to protect the device from being polluted and oxidized.
The clean and dry chamber is made of SUS304 high-quality stainless steel. The whole is welded by argon arc welding, and the gap is sealed to prevent air and dust particles from entering the oven. At the same time, nitrogen leakage can be saved. The outer box is powder-coated after being washed with soda water. The middle filling insulation material is high-density glass fiber cotton, which has good insulation effect. Can adopt layered structure design, the height of the layer can be adjusted, and it can be taken out freely. The box has movable casters, which can be pushed and fixed at will. The HEPA filter can achieve a filtration effect of 99.96%-99.99%. It can be repeatedly circulated to obtain a clean baking environment, and the cleanliness level can reach Class100 (5 micron particles in a cubic foot does not exceed 100).

Sanqing instrument clean oven adopts high temperature resistant high efficiency filter, filtration grade H13 (99.95% -99.99% @ 0.3um). Equipped with imported high temperature resistant microfiber core material, continuous temperature resistance of 300 ℃, stainless steel frame, aluminum foil partition, imported high temperature ceramic seal. Door frame is equipped with glass fiber heat-resistant sealing strip. When the equipment is turned on, the hot air circulation system is started, and the hot air circulation is realized by self-purification in the tank through the high-efficiency filter HEPA.
