Silicon nitride ceramic substrate material tape casting process
The invention relates to the technical field of silicon nitride ceramic substrate forming processes, and discloses a tape casting process of a silicon nitride ceramic substrate material. The manufacturing method comprises the following steps: carrying out first-time detection and finishing on a green sheet before drying after tape casting, drying after the first-time finishing, carrying out second-time detection and finishing after drying, and carrying out laminated adhesion after the second-time detection and finishing. Two times of detection and finishing are adopted in the procedure before sintering forming, grinding and polishing of the sintered ceramic substrate are reduced, meanwhile, detection and finishing are conducted on the green sheet before drying, the phenomenon that finishing is not facilitated or materials are wasted after drying due to the phenomena of blistering, cracking, deformation and uneven thickness of the green sheet can be avoided, and the production efficiency is improved. After drying, the green sheet is subjected to secondary detection and finishing, so that the change of the green sheet caused by drying can be finished, the complexity of grinding and polishing after sintering is reduced, the operation efficiency can be improved, the cutting loss is reduced, the generated stress is reduced, and the product quality is improved.
本发明涉及氮化硅陶瓷基片成型工艺技术领域，且公开了一种氮化硅陶瓷基片材料流延成型工艺；在流延成型后未干燥前，对生片进行第一次的检测修整，并在第一次修整后进行干燥，在干燥后再进行第二次的检测修整，第二次检测修整后才可进行叠层粘连，通过在对氮化硅陶瓷基片的制造过程中，位于烧结成型的前工序采用两次检测修整，减少烧结后陶瓷基片的打磨抛光，同时在干燥前对生片进行检测修整，可避免生片起泡、开裂、变形、厚度不均匀的现象而导致干燥后不利于修整或造成材料浪费的现象，在干燥后对生片进行二次检测修整可修整生片因干燥而造成的变化，减少烧结后打磨抛光的繁琐，可提高作业效率，减少切割损耗，并减少产生的应力，提高产品质量。
