As described in Fabricating & Metalworking in the article “Harsh Protection,” hermetic sealing is a crucial process in the assembly of microelectronic packages designed for extreme environments. By encasing sensitive electronic components within airtight metal or ceramic housings, hermetic sealing ensures long-term protection from contaminants such as moisture and dust.
Hermetic sealing is commonly used across industries including aerospace, defense, communications, and medical devices. Microelectronic systems in these sectors often involve components such as optical sensors, pressure sensors, power amplifiers, and laser or thermal imaging systems. In high-stakes applications where failure is not an option, these systems must be protected from environmental intrusion that can degrade performance or cause system failure.
