Non-oxidizing ovenIt is a drying equipment that creates low oxygen content in the cabinet and heats and bakes it. It is mainly used for anti-oxidation protection during baking, drying and curing for some devices that are relatively easy to oxidize, such as some metals. The main purpose of the non-oxidation oven is to perform front-end semiconductor functions such as wafer-level burn-in and magnetic annealing, as well as assembly/wafer-level encapsulation functions (such as die bond curing, stability and burn-in tests, and thermal shock) to meet Its annealing, drying and thermal decomposition requirements also meet the requirements of clean technology, low oxidation, and efficient curing of adhesives and polymers in large-scale semiconductor packaging and assembly production. Non-oxidizing ovens have been used by more and more factories. So, what parameters should be valued for non-oxidizing ovens? How to choose?
The non-oxidation oven is for the purpose of baking and drying, supplemented by an oxygen-free environment for the anti-oxidation protection of the device. For anaerobic construction, the most practical and economical method is to use nitrogen gas. While the oven is baking, it is filled with nitrogen to gradually integrate and replace the original air in the cabinet. After a certain period of nitrogen filling, the oxygen content in the cabinet will reach a very low level. At this time, if the baking is carried out, oxidation will still occur, but the oxidation of the baked items in the cabinet has become very slow. When it slows to within the acceptable range of the product, the non-oxidation purpose of the baked goods has been achieved. This is the job of the non-oxidizing oven.
Yee HingNon-oxidation ovenFeatures
