Outgassing control is critical in space flight applications. Materials
like laminate, masks and inks are tested for CVCM, WVR and TML and need
to meet certain levels to be used in space applications. Outgassing can
interfere with optics, devices, etc as these elements have much greater
impact to the system in a vacuum. Goddard publishes an 1124 data
manual, that you can get for no cost, listing the materials that have
already been tested. You can use these materials in lieu of testing to
meet outgassing requirements.

Subject: [TN] IPC 6012 : Outgassing Criteria
Hello,
I was reading this IPC 6012 when I come across Section 3.11.1 Outgassing
1. What actually is outgassing?
2. Why is outgassing critical for PCB?
3. As the PCB consist of so many processes and different materials go
into making it, where did the outgassing come from? 4. Is the criteria
mandatory for all Class PCB or only specified application?
5. If for only specific application, which application and why?
6. Come to think about it, can the outgassing come also from the coating
we use to seal the assembly?
Hope someone out there can share with me (novice) on this issue.
Thanks and regards,
Wee Mei
