JC-13 Fluorocarbon Tech Discussion

The end goal of this presentation is to make aware JEDEC members of needed modifications /updates in standards that use fluorocarbon electrical fluids to address test sensitivity (discuss potential root cause of False/Passes) and change of content in standards when mentioning trademark names of electrical fluids to be phase out by 3M due to PFAs content.

A Discussion of the Failure of a Quad Diode Module and Efforts to Assure the Flight Spares

In 2019 the International Space Station (ISS) experienced an on on-orbit failure that affected 1 of 28 Battery Charge Discharge Units (BCDUs). Telemetry pointed to a short circuit failure of a Power Rectifier Quad Diode Module. Astronauts removed the failed unit from service which was then returned to Earth for failure analysis. The failure analysis confirmed that the quad diode module had failed short circuit. The investigation identified silver dendrites had grown on the insulated, sloped edge of the mesa semiconductor die of the failed diode and also a 2nd diode in the same quad diode module. Voids between the diode’s protective encapsulating ring and the die provided space within which dendrites were able to form and cause catastrophic failure. The NASA Engineering & Safety Center (NESC) convened a EEE Parts Sub-Team to investigate root cause and to assist with risk assessment for all of the flight diode modules (4 distinct production lots) and the flight spares (from a 5th lot). Analysis of the original diode manufacturer’s read and record screening test data identified some lots which contained diodes with parametric instabilities that could signal conditions suited for silver dendrite formation. Computed Tomography (CT) X-ray screening inspection was performed on flight spare modules to identify diodes that do not exhibit voids between the edge of die and encapsulating ring as a mitigation against dendrite formation.

NASA - DLA Land And Maritime Survey of Qualified Product List Manufacturers to Understand Barometric Pressure Testing Electrical Biasing Conditions

NASA Marshall Space Flight Center (MSFC) in collaboration with DLA Land and Maritime-VAC support is conducting a survey to obtain feedback on the device electrical bias procedures specified in method 1001 of MIL-STD-750-1, Barometric Pressure (reduced)’. The purpose of this survey is to obtain input from the DLA Land and Maritime qualified manufacturer community to determine whether additional bias details or information should be specified within the test method. The survey results will be used to improve any test method deficiencies and result in consistent test results.
