 Beyond design and development of tailored COTS solutions, the Curtiss-Wright MCOTS team offers a number of advanced services:
- Functional Card Level Diagnostic Coverage Report:
- This type of document provides a detailed functional overview of a product that can be used to determine card level diagnostic coverage to:
- Determine functional architecture and component inventory (review schematics & FMECA data
- Develop a BIT coverage worksheet including MTBF and weighting (functional catalogue)
- Determine nodal analysis of each sub-function (failure catalogue)
- Perform CLD coverage (code) analysis as it applies to each sub-function
- Complete BIT coverage worksheet including CLD coverage weighting
- Calculate percent of BIT coverage
- Estimate criticality/severity of failure (for example, critical function CLD coverage percentage)
 Hazardous Material Report:
- This report provides the material analysis information for restricted use of hazardous material, as required by customers in the design and manufacture of their product. It examines four areas:
- Components
- PWB
- Mechanical and structural pieces
- Material usage during manufacturing
The report can also be used to report the component lead finish details.
- As an experienced supplier of products for defense platforms for over a quarter of a century we offer ruggedized air cooled and conduction cooled solutions. As part of our complete service offering, we thoroughly test all our cards for rugged environments. Our testing includes temperature cycling, shock and vibration, and we apply a conformal coat for humidity. We also offer more extensive test services for:
- Temperature, altitude or compartment: Our systems are tested at sea level. With avionics platforms, altitude changes will affect temperature and although our conduction cooled solutions are built to handle these environments some air cooled systems are not. As part of this service, we provide reports that allow customers to predict temperature based on altitude, air pressure and velocity.
- Explosive decompression: This test covers chassis, seals, connections, and gasket integrity. It tests how changes in air pressure outside a sealed box affect components while the inside pressure remains constant.
 Explosive atmosphere: This test service covers performance under two potential situations: a hot spark and a hot surface above flash point. The test is usually conducted to simulate a gas pipe or tank lead. - Sand and dust: With this pass/fail test we determine if contaminants can enter into fiber optics, cable connectors, and switch joints.
- Salt fog: Mostly applied for air force, marine and surface navy platforms, this test is for the corrosive effects of salt in the atmosphere. It examines areas that could corrode, including connector pins, as well as potential electrical shorts between objects (under BGAs, etc.). This test is usually conducted over 96 hours.
- Linear acceleration: This simulation test looks at how multiple G force turns (typically 10-12 G continuous) in an aircraft affect product components, such as connectors and frames, that could come dislodged during acceleration.
- EMI: Electrical magnetic interface testing.
These services leverage the unmatched design and development expertise the MCOTS team has built on an extensive library of market-leading COTS Intellectual Property, a multi-million dollar development and test infrastructure, and an experienced world class engineering workforce.
By leveraging lessons learned from years of development, the MCOTS team can help you reduce cost, reduce risk and improve time-to-market for any component destined for rugged defense and aerospace deployment.
