SEMs of burst 30-50-30 NSN SEPCON
Below are some SEM images of a burst 30-50-30 NSN membrane in a SEPCON pattern. Many similar chips failed at lower pressures, but this one survived to ~5-7 psi. (didn’t keep close track of the chips after they were burst, so I’m not sure which pressure this burst at, but it was within the 5-7 psi range)
It’s not clear to me what is causing failure on this chip but maybe after investigating some more standard OSO membranes we will be able to detect some differences.
