 ====== Commissioning work ======
+Always accepting sample donations! :-)
 I am happy to do some work for you:
-  * Decapping: destructive for epoxy packages, I am equipped to get the die out but the package will be broken in the process
+  * Decapping: always destructive for epoxy packages, I am equipped to get the die out but the package will be broken in the process thus the chip won't work; ceramic lidded packages should still work.
-  * Imaging: I can image using any of the listed optics for you with 20x typically being the highest for a full die, plus you can specify ROIs to be imaged at higher magnification
+  * Imaging: I can image using any of the listed optics for you with 20x typically being the highest for a full die, plus you can specify ROIs to be imaged at higher magnification.
-  * Deprocessing: I can deprocess the die down to the substrate, but without intermediate steps.
+  * Deprocessing: I can deprocess the die for simple dies with 1 metal layer so producing top metal/poly/substrate images. For dies with more than one metal layer, results will vary.
 The default package is, I do imaging top metal at 20x, decapping and/or deprocessing would obviously require more work and consume more material.
-If decapping is required, please bear in mind that it may result in damage/destruction of samples despite trying my best; providing multiple samples is highly desirable.
+If decapping is required, please bear in mind that it may result in damage/destruction of samples despite trying my best; providing multiple samples is highly desirable. Decapping different package types:
+  * Ceramic lidded packages is universally successful just by desoldering the lid. The chip will likely stay functional.
+  * Ceramic (non)windowed packages almost always succeeds unless the bottom part fractures from stress and takes the die with it. The chip will not be functioning due to frit fracturing.
+  * Epoxy DIP packages likely to succeed unless there is something funky about the die e.g. it's a multi-chip package, dies are very fragile, etc. The chip will not be functioning.
+  * Epoxy QFP and alike packages almost always succeeds as there is not much material to stress the die. The chip will not be functioning.
+  * Other packages to be discussed.
-Hobby/public projects are done for free but a small donation is always highly appreciated to cover material costs and tear&wear. You will have to cover shipping costs, including shipping samples back if so desired; I am EU-based so things might be simpler/cheaper if you are as well.

 At this moment, I **cannot** offer commercial work, and I **won't** do anything I deem legally challenging e.g. pay-TV, smartcards, DRM, crypto.
