Is Crest 3135 RTV or epoxy? Does thermal data exist for Epotek 377? 4

Regolith X-ray Imaging Spectrometer – REXIS – LL/MIT REXIS/OBF Telecon 10/11/12 C ONFORMAL C OATING OF F LEXPRINTS Flexprint active circuitry area requires some kind of coating for ESD protection Is solder mask enough? All vias on the board are tented If solder mask is not enough, what is recommended? Where should coating be done? LL or Kavli or by the vendor? 5

Regolith X-ray Imaging Spectrometer – REXIS – LL/MIT REXIS/OBF Telecon 10/11/12 M ATERIAL I NFORMATION FOR NASA NASA needs exact specifications on materials we are using in the package Need the following info (see attached spreadsheet) Assembly processes Materials used Standards/specifications for materials used Organics only: Amount used and outgassing data Need to file preliminary spreadsheet by 1/4/13 6

Regolith X-ray Imaging Spectrometer – REXIS – LL/MIT REXIS/OBF Telecon 10/11/12 CCD C HARACTERIZATION D ATA What is currently available or can be available soon? Harvard can plug in any available data to their simulations Is anything needed from MIT besides the wish list that was already sent over? I owe Keith a metrology wish list 7
