-===== Damage =====
-The back attach was very difficult to get off.  It was cooked in WFNA for 30 minutes in an attempt to release it.  In retrospect, this was too long of a period and caused the WFNA to dilute, resulting in minor corrosion.  It would have been better to do a 24 hour cold soak.
-After cooking with no effect, I gave up and was going to try to gently remove it.  After only very light handling, chunks started to come out of the back.  I immediately stopped trying to remove it and instead went to lightly pick it up to deposit into a vial.  The die then fractured from the tweezer pressure.
-There appears to be a scratch pre-dating the other damage (given that its corroded).  It is unclear where this came from.
-The die is quite dirty since I was not able to safely ultrasonic clean it.  Now that its been imaged, if there is desire for a cleaner image, I could try to clean it better but it may shatter.
