NASA-Issued Return to Flight Wristbands Banned from NASANASA Internal Advisory: NASA-Issued Return to Flight Wristbands Contaminated with Silicone
RESTRICTIONS ON RELEASE: The information in a NASA Advisory is for internal NASA use only. Distribution is limited to persons who require knowledge of its contents to aid them in minimizing adverse effects on NASA projects and equipment under their purview.
Neither NASA, the United States government, nor any person acting on their behalf, assumes any liability resulting from any distribution or use of this information.
Recently we have been made aware of a silicone problem associated with the "Return to Flight" wristbands. These wristbands are contaminated with silicone.
If you get silicone on the leads of a piece part, the silicone impairs the soldering process and gives a bad solder joint. Conformal coating will not stick to silicone either and will cause the parts on the board not to accept the conformal coating. What you need to know is that all of these type wristbands (Lance Armstrong's, Breast Cancer Awareness, and Return to Flight) use virtually the same production techniques, meaning that they are all contaminated with silicone. Therefore, caution should be exercised when wearing these wristbands.
ACTION TAKEN: Please do not wear these in our facilities and keep your eyes open for others that do not get this message. A Quality Alert has been issued at our Wasatch Facilities due to the serious nature of what silicone can do to our processes.
