Introduction In metallized ceramic production, several nickel plating failures are particularly frustrating for engineers: The nickel plating looks normal after electroplating but starts blistering after entering the brazing furnace; The tape test passes, but large-area delamination occurs after thermal cycling;

Introduction In modern industry, creating a reliable bond between ceramics and metals is a fundamental challenge in advanced manufacturing. However, ceramics, such as alumina ceramics, are highl chemically stable, making their surfaces difficult to wet with molten metals. In addition, the

Vacuum Feedthrough Overview and Engineering Challenges Vacuum feedthroughs transmit electrical, thermal, or mechanical signals across vacuum boundaries while maintaining hermetic integrity. Their performance directly determines the stability and reliability of vacuum systems in semiconductor, aerospace, and scientific applications. In vacuum engineering,

Introduction In semiconductor packaging, high-power electronics, aerospace systems, and precision sensors—any application involving hermetic sealing—an improper material selection may lead to reliability risks such as leakage, seal degradation, or even complete failure of the ceramic-to-metal interface. These failure mechanisms are
