Hi Scott, I can't recommend a material, but I have used this site to see if materials are NASA approved (low outgassing) http://outgassing.nasa.gov/ Good Luck! -----Original Message----- From: TechNet [mailto:[log in to unmask]] On Behalf Of Scott Decker Sent: Friday, February 10, 2006 9:56 AM To: [log in to unmask] Subject: [TN] Via fillings question. OK, fillings may sound like a dental term, but I mean via plugging materials. :-) I'm looking for what materials I can use to plug a .010" via and meat NASA specs for out gassing, etc. I have some names so far, but no data on if they are approved for space apps. The names are so far: Peters fill (maybe this is a spec number, SD2795?) and is non-conductive? CB100, which I know is OK for space and conductive, but FAB would need a jack hammer to get it in a .010" hole so that's out. And last I have is San-IE, which I understand is non-conductive and supposed to be good in space, but San-IE what? For this project I don't need conductive but they will be under a BGA so it will need to be flat and covered with solder mask. I got that part covered, (no pun intended) but I just need to know what to call out on my drawing. Any help would be great. Later.
