5. Have harsh environment testing performed by a test lab that has many years of experience with multiple test processes that replicate the extreme variables connectors face in harsh environments. A wide range of environmental testing should be done, including exposure to mixed flowing gas, humidity, temperature, salt fog, dust, and thermal cycling. Testing for shock and vibration using drum- like systems can mimic aircraft and drone vibrations. Testing components for corrosive reactions, moisture resistance, temperatures at altitude, and plating durability helps ensure the product will perform reliably in its expected operational setting.
use solid modeling can help tailor existing high- reliability designs to fit the device. 2. Review harsh-environmental requirements with the connector and cable supplier to ensure the appropriate cable, metals, plating, and polymers fit within the application. (For example, outgassing levels of epoxies must meet NASA specifications if the component is used in space applications.) 3. When the first solid models are ready, request delivery of a 3D prototype to insure both cable and connectors fit within the design. 4. When the final interconnect is approved for size, shape, materials, and construction, have multiple sets built up for harsh environment reliability testing.
