HTCC腔体成型工艺改善研究OA

To address the common issue of deformation in high-temperature co-fired ceramic(HTCC)cavities during the molding process,a combined method featuring"stepwise pre-pressing followed by assembly lamination"and a"retracted polyethylene terephthalate(PET)film"technique is proposed.This approach provides a universal solution for improving cavity performance when dealing with forming challenges associated with various cavity structures.At the same time,the pre-pressing pressure and retraction distance are optimized,effectively mastering the cavity manufacturing process technology and ensuring molding quality.Consequently,the cavity surface flatness is controlled within 20 μm.The products fabricated using this method meet the requirements of reliability verification,which provides a valuable reference for cavity molding.
