Also, Sue, I forgot to mention IPC-TM-650 has several test methods to determine moisture resistance to both liquid immersion and absorption from air based on RH. The TMs are numbered 2.6.2, 2.6.3, and in that general area of TM-650. There are also some TMs for measuring bakeout times for different PWB materials. Let me know if you cannot find them. -----Original Message----- From: TechNet [mailto:[log in to unmask]] On Behalf Of Stadem, Richard D.
